“要不”“不然”的连接功能及异同分析

'要不'和'不然'在现代汉语中的语法功能非常相近,但目前研究的主要关注点在于它们各自的特点,对两者之间的差别研究得还不够透彻。文章在总结'要不'和'不然'功能的研究成果的基础上,着重对'选择类'和'因果类'连接功能展开了进一步的考察,接着进一步分析'要不'和'不然'在连接功能下的差异。最终得出,'不然'在表示选择、建议和因果方面受到限制,即在选择关系中不能表示'相容性'选择,在建议关系中不能表示'命令式'建议,在因果关系中不能表示'说明性'因果和'醒悟性'因果。这种情况的产生是由'不然'所具有的强调前分句的特殊功能决定的。

Cautiously using natural medicine to treat liver problems

Natural medicine is a system of therapy that administrates natural agents and their derivatives to treat human diseases.This medicine has been used to treat many kinds of human diseases for thousands of years.The treatment protocols of natural medicine are integrative in nature,and are required to utilize the most appropriate therapies to address the needs of the individual patient.Because of the relative convenience,safety and efficacy,natural medicine is now increasing worldwide.Naturopathic doctors are licensed in many areas of the world and regulated partly by law in these areas,which is quite different from various other forms of complementary and alternative medicine.Liver diseases,such as hepatitis,liver cirrhosis and liver carcinoma,are serious health problems worldwide.Nearly half of the natural agents used in treatment of liver diseases today are natural products and their derivatives.Although natural medicine is beneficial and safe,physicians should pay close attention to the potential side-effects of the naturopathic agents,which lead to liver injury,interstitial pneumonia and acute respiratory failure.Therefore,when administrating naturopathic protocols to patients for the treatment of liver diseases,we should try our best to prevent and avoid as much as possible the negative impact of these medicines.This article highlights the current practice and recommended improvement of natural medicines in the treatment of liver diseases and gives some specific examples to emphasize the prevention and management of adverse reactions of the natural agents and suggests that natural medicine should be cautiously used to treat liver problems.

Indexes of Indoor Thermal Environment with Asymmetrical Radiant Field

The main features of top-flcor rooms with natural ventilation are identified by investigating indoor thermal environment in summer season. One is high indoor air temperature, for this reason the indoor climate is far beyond the thermal comfort standard; the other is the inhomogeneons temperature distribution of the inner wall surfaces, and high temperature of the inner surface of the roof causes much scorching to the head of occupant. This is the characteristic of such rooms. Both features mentioned above should be considered comprehensively for the evaluation of indoor thermal environment of the top-floor rooms with asymmetric radiant field. In order to characterize the indoor thermal environment of the rooms, the heat stress index, HSI and radiant heat flux reaching human head, Q_R should be introduced simultaneously as thermal indexes for the indoor climate evaluation. The application of the indexes to a topfloor room is presented and analyzed.

Comparative Life-cycle Assessment of Sheet Molding Compound Reinforced by Natural Fiber vs. Glass Fiber

We present comparative life-cycle assessments of three fiber-reinforced sheet molding compounds （SMCs） using kenaf fiber, glass fiber and soy protein resin. Sheet molding compounds for automotive applications are typically made of unsaturated polyester and glass fibers. Replacing these with kenaf fiber or soy protein offers potential environmental benefits. A soy-based resin, maleated acrylated epoxidized soy oil （MAESO）, was synthesized from refined soybean oil. Kenaf fiber and polyester resins were used to make SMC 1 composites, while SMC2 composites were made from kenaf fiber and a resin blend of 20% MASEO and 80% unsaturated polyester. Both exhibited good physical and mechanical properties, though neither was as strong as glass fiber reinforced polyester SMC. The functional unit was defined as mass to achieve equal stiffness and stability for the manufacture of interior parts for automobiles. The life-cycle assessments were done on SMCI, SMC2 and glass fiber reinforced SMC. The material and energy balances from producing one functional unit of three composites were collected from lab experiments and the literature. Key environmental measures were computed using SimaPro software. Kenaf fiber-reinforced SMC composites （SMC1 and SMC2） performed better than glass fiber-reinforced SMC in every environmental category. The global warming potentials of kenaf fiber-reinforced SMC （SMCI） and kenaf soy resin-based SMC （SMC2） were 45% and 58%, respectively, of glass fiber-reinforced SMC. Thus, we have demonstrated significant ecological benefit from replacing glass fiber reinforced SMC with soy-based resin and natural fiber.

Effects of Different Natural Organic Additives on in Vitro Shoot Regeneration of Raphanus sativus L. Var, Beeralu

Abstract： Raphunus sativus L. commonly known as ＂radish＂ is a popular vegetable crop used by people all over the world for its culinary and medicinal properties. Enhancement of in vitro regeneration system for radish variety beeralu is needed to further tissue culture studied. Therefore, the present study was carried out to find out the effects of different organic additives on in vitro shoot regeneration of Radish （Raphanus sativus L.） Var. Beeralu. Hypocotyl explants of aseptic plantlets were cultured on MS basal medium supplemented with 2.5 mg/L BAP （benzyl adenine） and 0.1 mg/L NAA （1-nphthaleneacetic acid） with different natural additives; 20% coconut water, 20% coconut milk, 10% grind spinach leaves, 10% grind potato tubers, 10% grind carrot, 5% rice flour, 10% green gram, 10% grind pumpkin, 10% banana fruit, 10% orange and control （without any additives）. Complete randomized design （CRD） with five replicates was used. After one month the numbers of regenerated shoots were counted and statistical analysis was carried out using the Student Newman-Kuells Means Separation Test of SAS program （9.1.3）. The highest mean number of shoots （12 shoots/explant） from Radish （Raphanus sativus L.） Var. Beeralu observed in MS basal medium with 2.5 mg/L BAP and 0.1 mg/L NAA with 10% orange juice whereas the 2nd highest shoots were obtained with 20% coconut water. The lowest number of shoots （0 shoot/explant） was observed from medium with carrot juice and pumpkin juice, but they induced callus formation. Media with grind spinach leaves, rice flour, green gram, grind potato tubers and banana inhibit the shoot regeneration.

Primary Discussion of a Carbon Sink in the Oceans

As a consequence of global warming and rising sea levels, the oceans are becoming a matter of concern for more and more people because these changes will impact the growth of living organisms as well as people＇s living standards. In particular, it is extremely important that the oceans absorb massive amounts of carbon dioxide. This paper takes a pragmatic approach to analyzing the oceans with respect to the causes of discontinuities in oceanic variables of carbon dioxide sinks. We report on an application of chemical, physical and biological methods to analyze the changes of carbon dioxide in oceans. Based on the relationships among the oceans, land, atmosphere and sediment with respect to carbon dioxide, the foundation of carbon dioxide in shell-building and ocean acidification, the changes in carbon dioxide in the oceans and their impact on climate change, and so on, a vital conclusion can be drawn from this study. Specifically, under the condition that the oceans are not disturbed by external forces, the oceans are a large carbon dioxide sink. The result can also be inferred by the formula： C=A-B and G=E＋F when the marine ecosystem can keep a natural balance and the amount of carbon dioxide emission is limited within the calrying capacity of the oceans.

Natural Processes for the Restoration of Dam Removal Disturbances

The Heber River Diversion Dam （Heber Dam） and 3.6 km penstock on Vancouver island, British Columbia, Canada was built in 1953 and by 2009, it had reached the end of its useful life due to the deteriorated wooden structures. A decision was taken to remove the dam, return the flows in the Heber River to pre-dam conditions and restore the footprint of the dam and penstock. Plans were developed for removal of the dam and contaminated materials including the creosote coated wooden penstock and other wooden structures associated with the dam and site restoration. Work on removal and restoration was undertaken over the summer and fall of 2012 and the spring of 2013. Restoration treatments were based on the use of natural processes as a model for recovery. The recovery of dam and penstock removal disturbances was initiated in the late summer and fall of 2012 with the fall dispersal of seeds from mature pioneering species that formed a significant part of the local undisturbed vegetation. This paper describes the treatments that were applied to enhance the natural recovery of the disturbed areas and the results of those treatments. The restoration treatments were designed to address the filters that were present in project areas. These were identified during an initial inspection in 2009 and were centred on compaction of substrates and a lack of micro-sites. In addition to the use of natural processes for the restoration of project disturbances, a local First Nations crew was hired to transplant sword ferns （Polystichum munitum （Kaulf.） C. Presl） from the adjacent forest areas onto project sites to provide a social benefit from the restoration work.

Gas-Fluid and Fluid-Solid Phase Instability for Restricted Primitive Model

By considering the fluctuation of grand potential f~ around equilibrium with respect to small one-particle density fluctuations δpα（r→）, the phase instability of restricted primitive model （RPM） of ionic systems is investigated. We use the integral equation theory to calculate the direct correlation functions in the reference hypernetted chain approximation and obtain the spinodai line of RPM. Our anaiysis explicitly indicates that the gas-fluid phase instability is induced by k = 0 fluctuation mode, while the fluid-solid phase instability is related to k ≠ 0 fluctuation modes. The spinodai line is qualitatively consistent with the result of computer simulations by others.

Corporate Social Responsibility——From the Perspective of Polish Enterprises

Corporate social responsibility （CSR） is becoming more and more frequently emphasized part of management in the structure of Polish enterprises. These results from the fact that growing awareness of consumers, destructive impact of industry on the natural environment, economic scandals, unethical behavior among entrepreneurs, bring about redefining the principles of a business activity on the market by entrepreneurs. As a result of the above, such values as honesty, trust, or responsibility take on greater importance. Additionally, more and more often, Polish entrepreneurs pay attention to the influence of the company on the environment, the way the stakeholders are treated, while striving to maximize profit. The present paper looks into the subject of social responsibility from the point of view of Polish enterprises. To verify this objective, there was the analysis of the due literature performed, and also carried out the survey among 174 entrepreneurs running their business activity in the area of Southern Poland. The research tool used in the research was the questionnaire （PAPI and CAWI）. In the conducted research, there were factors analyzed referring to knowledge of social responsibility among the people holding both managerial and lower-level positions, in particular opinion, is it important for enterprises to be driven by ethical standards？ How to implement CSR in their structures？ How to understood concept of CSR？ What are the reasons for the implementation of CSR in the strategy of the company？ The considerations （both the theoretical and practical ones） confirmed that the Polish enterprises feel the increased need to implement the activities in the field of social responsibility, which, in the present conditions, constitutes an important part of running a business activity.

An Experimental Study on the Performance of a Stainless Steel-Water Loop Heat Pipe under Natural Cooling Condition

Aiming to improve the thermal characteristics of modern electronics, we experimentally study the performance of a stainless steel/water loop heat pipe(LHP) under natural cooling condition. The LHP heat transfer performance, including start-up performance, temperature oscillation and total thermal resistance at different heat loads and with different incline angles have been investigated systematically. Experimental results show that at an optimal heat load(i.e. 60 W) and with the LHP being inclined 60 to the horizontal plane, the total thermal resistance is lowered to be ~0.24 K/W, and the temperature of evaporator could be controlled steadily at around 90 C.

On the Simulation of Industrial Gas Dynamic Applications with the Disconti- nuous Galerkin Spectral Element Method

In the present investigation, we demonstrate the capabilities of the discontinuous Galerkin spectral element method for high order accuracy computation of gas dynamics. The internal flow field of a natural gas injector for bivalent combustion engines is investigated under its operating conditions. The simulations of the flow field and the aeroacoustic noise emissions were in a good agreement with the cxperirnental data. We tested several shockcapturing techniques for the discontinuous Galerkin scheme. Based on the validated framework, we analyzed the development of the supersonic jets during different opening procedures of a compressed natural gas injector. The results suggest that a more gradual injector opening decreases the noise emission.

The nonlinear theory for sediment ripple dynamic process of straight river

There are various sand tipples in the natural world. The viewpoint of Yalin is that local disturbances result in laminar instability and in sand-tipple formation, namely, local disturbance^the instability of the laminar flow→the formation of sand ripples. Based on this viewpoint, a theoretical model of the resonant triad interaction and its nonlinear interaction with the sediment is established. The purpose of this model is to explain the formation and evolution of the sand-tipple and allow for analysis of the instability of open-channel flow caused by it and sand-tipple hydro-dynamic process. This model will not only pave a road to explore the mechanism of interaction between bed-form and turbulence, but also provide a good base for the study of aeolian sand-tipple formation.

Chemosensory response in stunted prairie rattlesnakes Crotalus viridis viridis

Rattlesnakes use chemical stimuli in ambush site selection and for relocation of envenomated prey through atrike-induced chemosensory searching. Shifts in responsiveness to prey chemicals have been documented in many snakes, and often correlate with prey commonly taken as snakes increase in age and size as well as geographical locations of the species. For instance, neonate rattlesnakes that prey primarily on ectotherms responded most strongly to chemical cues of commonly taken lizard prey, whereas adult rattlesnakes that prey primarily on small mammals responded significantly to chemical cues of com- monly taken rodents. In the current study, 11 Prairie Rattlesnakes Crotalus viridis viridis which were classified as large neonates based on measures of snout-vent length （SVL） and body mass, yet chronologically were at or near adulthood, were tested for their responsiveness to chemical extracts of natural and non-natural prey items. Although the snakes had eaten only neonate lab mice （Mus musculus）, they responded significantly more to chemical cues of natural prey items and particularly to chemical cues of prey normally taken by subadults （Peromyscus mice and Sceloporus lizard）. These results suggest that ontogenetic shifts in re- sponsiveness to natural prey chemical cues are innately programmed and are not based on body size or feeding experience in C. v. viridis. This does not imply, however, that growth and experience are without effects, especially with novel prey or rare prey that have experienced recent population expansion [Current Zoology 59 （2）： 175-179, 2013].

Timing,scale and mechanism of the destruction of the North China Craton

The North China Craton (NCC) is a classical example of ancient destroyed cratons.Since the initiation of the North China Craton Destruction Project by the National Natural Science Foundation of China,numerous studies have been conducted on the timing,scale,and mechanism of this destruction through combined interdisciplinary research.Available data suggest that the destruction occurred mainly in the eastern NCC,whereas the western NCC was only locally modified.The sedimentation,magmatic activities and structural deformation after cratonization at ～1.8 Ga indicate that the NCC destruction took place in the Mesozoic with a peak age of ca 125 Ma.A global comparison suggests that most cratons on Earth are not destroyed,although they have commonly experienced lithospheric thinning;destruction is likely to occur only when the craton has been disturbed by oceanic subduction.The destruction of the NCC was coincident with globally active plate tectonics and high mantle temperatures during the Cretaceous.The subducted Pacific slab destabilized mantle convection beneath the eastern NCC,which resulted in cratonic destruction in the eastern NCC.Delamination and/or thermal-mechanical-chemical erosion resulted from the destabilization of mantle convection.

Application of profile likelihood function to the uncertainty analysis of hydrometeorological extreme inference

Profile likelihood function is introduced to analyze the uncertainty of hydrometeorological extreme inference and the theory of estimating confidence intervals of the key parameters and quantiles of extreme value distribution by profile likelihood function is described.GEV(generalized extreme value)distribution and GP(generalized Pareto)distribution are used respectively to fit the annual maximum daily flood discharge sample of the Yichang station in the Yangtze River and the daily rainfall sample in10 big cities including Guangzhou.The parameters of the models are estimated by maximum likelihood method and the fitting results are tested by probability plot,quantile plot,return level plot and density plot.The return levels and confidence intervals of flood and rainstorm in different return periods are calculated by profile likelihood function.The results show that the asymmetry of the profile likelihood function curve increases with the return period,which can reflect the effect of the length of sample series and return periods on confidence interval.As an effective tool for estimating confidence interval of the key parameters and quantiles of extreme value distribution,profile likelihood function can lead to a more accurate result and help to analyze the uncertainty of extreme values of hydrometeorology.

Shallow water equations for power law and Bingham fluids Dedicated to the NSFC-CNRS Chinese-French summer institute on fluid mechanics in 2010

In this note, we provide a consistant thin layer theory for power law and Bingham incompressible fluids flowing down an inclined plane under the effect of gravity. The derivation of such equations is based on formal asymptotic expansions of solutions of Cauchy momentum equations in the shallow water scaling and in the neighbourhood of steady solutions so that we can close the average equations on the fluid height h and the total discharge rate q.
