清末白话小说中条件类纪效连接成分研究

表条件的连接(connective)成分是纪效(cause-result)连接成分中的一个类别,根据对条件的界定,可以将其分为5个层次:顺承条件类、假设条件类、排除条件类、相反条件类及毋论条件类。这5个类别的纪效连接成分在清末白话体小说中均有所体现。通过比较可知,作为承上启下的中间环节,清末条件类纪效连接成分有一些内容与现代的连接成分相一致,但其构形区别具有明显的时代性特征。

Extraction of betulin from bark of Betula platyphylla by supercritical carbon dioxide extraction

Betulin, which is a medicinal pentacyclic triterpene, is abundant in the bark of white birch (Betula platyphlly). The bark of birch was collected at Tayuan Forest Farm of Jiagedaqi, Heilongjiang Province in September 2000. Supercritical fluid extraction (SFE) that is a new separation technology has been used for the processing pharmaceutical and natural products. In this paper, the extraction of betulin from the bark of birch by supercritical CO2 extraction was studied. The authors investigated and analyzed a few parameters such as modifier dosage, extraction pressure and extraction temperature. The optimal extrac-tion conditions showed that the modifier dosage used for per gram bark powder was 1.5 mL, the extraction pressure was at 20 Mpa, and the extraction temperature was at 55 C. The velocity of flow of liquid CO2 was at 10 kg/h. The pressure and tem-perature in separation vessel were at 5.5 Mpa and 50 C, respectively.

西部地区居民收入差距及其解构——基于CFPS项目数据的研究

立足于西部地区经济发展的阶段以及相对贫困的治理要求,利用中国家庭追踪调查项目西部地区的数据,选取基尼系数和一组广义熵族指数,对研究期内的收入差距进行了单分布的概要测量和比较,并以相对极化指数的测量结果予以补充。结果发现,自2012年以来我国西部地区的收入差距逐年递增,收入分布的离散度渐趋扩大。基尼系数和广义熵族指数的分解结果表明,各类别组内收入差异是收入差距的主要来源,同一类别各组收入差异对收入差距的贡献也不相同。而分位数回归结合反事实方法的动态分解结果则显示,反映资源分类机制的条件成分才是收入差距产生变异的根本原因。

Effects of Different Yellowing Conditions on Neutral Aroma Components and Smoking Quality of Flue-cured Upper Leaves

A heated air circulation standard curing barn was used for baking tobacco leaves, and the effects of different yellowing conditions during the baking process on contents of neutral aroma components and smoking quality of upper leaves were studied by setting different yellowing time and color-fixing time. The results showed that during the baking process, only by prolonging the yellowing time by 24 h on the basis of control, the content of every kind of neutral aroma components in- creased obviously and the content of solanone increased by nearly 2.20 times. It was unfavorable for the degradation and accumulation of aroma components when only prolonging color-fixing time by 24 h. Prolonging both yellowing time and color- fixing time by 24 h mainly promoted the accumulation of chlorophyll degradation product neophytadiene, which increased by 33.24%, while the degradation and ac- cumulation of some aroma components were inhibited, indicating that only prolonging the yellowing time by 24 h could promote the accumulation of various kinds of neu- tral aroma components and improve the quality of tobacco leaves. The regression models were established of neutral aroma components in the first and second prin- cipal components to total aroma content, which were y=x＋0.053 47 （R^2=0.919 7） and y=x＋0.147 5 （R^2=0.698 4）, respectively, and they were verified to be feasible.

A New Class of Biased Linear Estimators in Deficient-rank Linear Models

In this paper, we define a new class of biased linear estimators of the vector of unknown parameters in the deficient_rank linear model based on the spectral decomposition expression of the best linear minimun bias estimator. Some important properties are discussed. By appropriate choices of bias parameters, we construct many interested and useful biased linear estimators, which are the extension of ordinary biased linear estimators in the full_rank linear model to the deficient_rank linear model. At last, we give a numerical example in geodetic adjustment.

A stabilized least-squares imaging condition with structure constraints

Conventional shot-gather migration uses a cross-correlation imaging condition proposed by Clarebout （1971）, which cannot preserve imaging amplitudes. The deconvolution imaging condition can improve the imaging amplitude and compensate for illumination. However, the deconvolution imaging condition introduces instability issues. The least-squares imaging condition first computes the sum of the cross-correlation of the forward and backward wavefields over all frequencies and sources, and then divides the result by the total energy of the forward wavefield. Therefore, the least-squares imaging condition is more stable than the classic imaging condition. However, the least-squares imaging condition cannot provide accurate results in areas where the illumination is very poor and unbalanced. To stabilize the least-squares imaging condition and balance the imaging amplitude, we propose a novel imaging condition with structure constraints that is based on the least-squares imaging condition. Our novel imaging condition uses a plane wave construction that constrains the imaging result to be smooth along geological structure boundaries in the inversion frame. The proposed imaging condition improves the stability of the imaging condition and balances the imaging amplitude. The proposed condition is applied to two examples, the horizontal layered model and the Sigsbee 2A model. These tests show that, in comparison to the damped least-squares imaging condition, the stabilized least-squares imaging condition with structure constraints improves illumination stability and balance, makes events more consecutive, adjusts the amplitude of the depth layers where the illumination is poor and unbalanced, suppresses imaging artifacts, and is conducive to amplitude preserving imaging of deep layers.

Mantle plume activity and melting conditions： Evidence from olivines in picritic-komatiitic rocks from the Emeishan Large Igneous Province, southwestern China

Olivine phenocryst compositions and whole-rock chemical compositions are used to identify primitive picrite basalts from the early part of flood basalt successions in the western part of the Emeishan large igneous province （ELIP）, southwestern China. The Fo contents of olivine phenocrysts of komatiites with MgO-21.79 wt% range from 85.2% to 91.4%. The composition of unerupted parental melts is calculated from the compositions of the most Fo-rich olivine phenocrysts. These melts had -22 wt% MgO, and originated in mantle with a potential temperature of -1600℃ and at about 4.2 GPa pressure, supporting the conclusion that the generation of ELIP can be attributed to melting of a plume head beginning at -138 km depth.

Inversion of two-dimensional tidal open boundary conditions of M_2 constituent in the Bohai and Yellow Seas

Two-dimensional tidal open boundary conditions of the M2 constituent in the Bohai and Yellow Seas(BYS) have been estimated by assimilating T/P altimeter data.During inversion,independent point(IP) strategy was used,in which several IPs on the open boundary is assumed,values at these IPs can be optimized with an adjoint method,and those at other grid points are determined by linearly interpolating the values at IPs.The reasonability and feasibility of the model are tested by ideal twin experiments.In the practical experiment(PE) after assimilation,the cost function may reach 1% or less of its initial value.Mean absolute errors in amplitude and phase can be less than 5 cm and 5°,respectively,and the obtained co-chart can show the character of the M2 constituent in the BYS.The results of the PE indicate that using only two IPs on the open boundary can yield better simulated results.

Organotemplate-free Hydrothermal Synthesis of SUZ-4 Zeolite: Influence of Synthesis Conditions

Various conditions were investigated in detail for the novel organic template-free static hydrothermal synthesis of SUZ-4 zeolite in the presence of seeds. The obtained samples were characterized by XRD （X-ray diffraction）, SEM （scanning electron microscope）, TG （thermal gravimetric analysis）, ICP （inductively coupling plasma） elemental analysis, nitrogen sorption isotherm and surface area. The results show that pure SUZ-4 zeolites with high crystallinity are obtained in a broad window of synthesis conditions： seed mass concentration 0.2%-2%, SIO2/A1203 molar ratio 21 25, KOH/SiO2 molar ratio 0.33 0.43, H20/SiO2 molar ratio 7.14-38.1, aging time 24 h, crystallization temperature 160℃, and crystallization time 6-10 d. Also, crystallinity and size of the rod-like SUZ-4 zeolite crystals are found to alter with the conditions.

Scalable Arbitrated Quantum Signature of Classical Messages with Multi-Signers

Unconditionally secure signature is an important part of quantum cryptography. Usually, a signature scheme only provides an environment for a single signer. Nevertheless, in real applications, many signers may collaboratively send a message to the verifier and convince the verifier that the message is actually transmitted by them. In this paper, we give a scalable arbitrated signature protocol of classical proved to be secure even with a compromised arbitrator. messages with multi-signers. Its security is analyzed and proved to be secure even with a compromised arbitrator.

Regimes of Runoff Components on the Debris-covered Koxkar Glacier in Western China

By using a degree-day based distributed hydrological model, regimes of glacial runoff from the Koxkar glacier during 2007-2011 are simulated, and variations and characteristics of major hydrological components are discussed. The results show that the meltwater runoff contributes 67.4%, of the proglacial discharge, out of which snowmelt, clean ice melting, buried-ice ablation and ice-cliff backwasting account for 22.4%, 21.9%, 17.9% and 5.3% of the total melt runoff, respectively. Rainfall runoff is significant in mid-latitude glacierized mountain areas like Tianshan and Karakorum. In the Koxkar glacier catchment, about 11.5% of stream water is initiated from liquid precipitation. Spatial distributions for each glacial runoff component reveal the importance of climatic gradients, local topography and morphology on glacial runoff generation, and temporal variations of these components is closely related to the annual cycle of catchment meteorology and glacier storage. Four stages are recognized in the seasonal variations of glacier storage, reflecting changes in meltwater yields, meteorological conditions and drainage systems in the annual hydrological cycle.

Fish Sauce Fermentation with Silver Carp or Offal of Surimi Processing

Fish sauce is a kind of condiments processed from fish. The L9（34） orthogonal tests have been carried out to inspect the effects of technological conditions for fermentation on the comprehensive quality of fish sauce. The conditions of the orthogonal tests are following: the fermentation temperature takes values of 35℃, 40℃ and 45℃, the percentage of Koji values of 40%, 20% and 10% and the percentage of salt values of 10%, 14% and 18%. The obtained experimental results indicate that fermentation temperature plays an important role in the improvement of sauce quality. The optimal technological conditions for sauce fermentation are of 10% salt, 45℃ and 40% koji mixed. The composition of fish sauce processed from offal of silver carp-surimi processing under the above-mentioned conditions and two commercial products have been analyzed. The results show that fish sauce processed from fish offal is nutritious and delicious. It is suggested that the fermentation of fish sauce is a potential and promising pathway to make full use of freshwater fish resources and offal in fish processing. In this study, fuzzy theory and analytic hierarchy process have been applied and the quality evaluation has been established by the combination of physico-chemical indices and sensory evaluation. The comprehensive evaluation has been taken to reflect the optimal factors for the process of sauce fermentation. The quality indexes for fish sauce contain sensory evaluation, amino nitrogen, total nitrogen, specific gravity, volatile basic nitrogen, salt concentration, brown index and acidity, represented by y1, y2, y3, y4, y5, y6, y7, y8, and y9, respectively. They form a group U= {y1, y2, y3, y4, y5, y6, y7, y8, y9,}. Using the fuzzy functions, the values of all these factors are transformed into fuzzy degrees of single factor, i.e. numerical values between 0 and 1. The fuzzy degrees of single factor in several samples are made up a matrix R. Following that, a weight of each index can be determined in the comprehensive evaluation. In the analytic hierarchy process, the weight can be obtained by the cross comparison between two different factors. The results show that the weights （W） of sensory evaluation, amino nitrogen, total nitrogen, specific gravity, volatile basic nitrogen, salt concentration, brown index and acidity are 0.356, 0.189, 0.107, 0.054, 0.097, 0.063, 0.061 and 0.073 respectively. Finally the aggregated fuzzy degree （B） of different samples is computed by B=W·R, which can be taken as the final result of comprehensive evaluation. The larger this value is, the higher the quality of sauce product would be.

Impact of Solid / Vapour Equilibria on Conditions of Crystallization of Pharmaceutical Compounds

The influence of solvent (in its gaseous state) on the stability of crystallized organic compounds was investigated. Through two examples of studies on the solid/vapour equilibria made in our lab, several behaviors were highlighted: (i) a new hydrated phase (thermodynamically stable) of an active pharmaceutical ingredient (API) was detected after the recrystallization starting from a deliquescent state, (ii) a spontaneous resolution of a hydrated racemic compound towards an anhydrous conglomerate can occur during the desolvation under the precise conditions of temperature and humidity. This study illustrates that knowledge about solid/vapour equilibrium is a crucial step during the complete characterization of solid organic compounds.

Controlling the effect of a distant extremely thick igneous rock in overlying strata on coal mine disasters

Based on theoretical analysis, similarity simulation tests, numerical simulation analysis and field observations, we analyzed rock collapse and rules of fraction evolution of overlying rocks and studied the rules in controlling the effect of an extremely thick igneous rock, found above a main mining coal seam in an area prone to coal mine disasters in the Haizi Coal Mine. The results show that this igneous rock, called a "main key stratum", will not subside nor break for a long time, causing lower fractures and bed separations not to close. The presence of igneous rock plays an important role in rock bursts, mine floods, gas outburst and surface subsidence in coal mines. By analyzing the rules in controlling the effect of this igneous rock, we provide useful references for safety and high efficiency mining in coal mines under special geological conditions.
