词是逐渐增长的黎明,是可靠的故乡——杨方诗集《骆驼羔一样的眼睛》阅读印象

诗人杨方,是首都师范大学中国诗歌研究中心的驻校诗人,其诗集《骆驼羔一样的眼睛》,以诗"词"题,有一种漫溯的效果,她让词成为她的诗意构成方式,成为一种诗歌的物件,并成为灵魂的一件护身符,从而呈现了她的经世之思与内在情调。故乡,是她的原初的情结,是故乡之于她的纠结和疼痛。花间、草木、流水,是她寻找到的可靠的遮蔽,并逐渐完成一种整合的、有节律的诗性生命形式,市诗性文化的浪漫体验和精神故乡的现实寻根,有机成为整体,完成陶醉和安放的永无止息的生态境遇和精神归宿。秋风,是她获取的清醒的力量。杨方依靠内心的力量离开了自身,观看和瞩望着秋风中万事万物的存在与涅,在精神故乡的永恒追寻中,她保持着对深不可测的生存意图的真诚。

Effects of Fertilization on Young Populus deltoids cv. Zhonghua Hongye Growth

Using complete and orthogonal design, fertilization trials were conducted for the young growth of Populus deltoids cv. Zhonghua hongye in the fluviogenic soil in Xindu District, Chengdu City. The results showed that the application ef- fect of the single nutrient elements ranked as K〉N〉P, and that of the fertilization combinations ranked as N＋P＋K〉N＋K〉N＋P, P＋K. The optimum fertilization formula was urea [（NH2）2CO, 150 g/plant] ＋ calcium superphosphate [Ca（H2PO4）2.H20, 220 g/plant] ＋ potassium sulphate （K2SO4, 75 g/plant）.

INTRODUCTION TO PROF. YANG YUN-KUAN'S THE NEEDLING TECHNIQUE OF MIND REGULATION AND TAOISM CONCENTRATION

The combination of needling technique of Mind Regulation with Taoism Concentration is to promote the propagated sensation along the channels （PSC） and the needling sensation to the affected area in order to activate the potential regulation of human body. Prof. Yang Yun-kuan used this combination to treat some pain diseases, nervous system＇s diseases and intractable chronic diseases and got a better result than the general techniques, This is the introduction to the manipulation of this technique and its clinical application.

Preliminary Research on the Mathematical Methods and Order of Problems in the“Fungcheng”Chapter of Yang Hui's Mathematical Methods(1261 CE)

Yang Hui was one of the most important authors of mathematical works during the thirteenth century.Mathematical Methods Explaining in Detail The Nine Chapters(Xiangjie jiuzhang suanfa詳解九章算法,1261 CE)is the earliest extant work attributed to Yang Hui.From the thirteenth to the fifteenth century,this work played a crucial role in the circulation and popularization of The Nine Chapters on Mathematical Procedures(Jiuzhang suanshu九章算术).However,the only surviving printed edition of Mathematical Methods is incomplete and contains many mistakes obstructing contemporary researchers'understanding of this work.The "Fangcheng" chapter of The Nine Chapters deals with problems related to solving what today are known as simultaneous sets of linear equations.However,interpreting the text in this chapter of Mathematical Methods and recovering the mathematical practices relating to fangcheng are difficult.Through detailed textual and mathematical analyses,the author of this paper explains Yang Hufs understanding and practice relating to〃the fangcheng method"and"the method of the positive and the negative".This paper includes an appendix that provides a detailed translation of the ambiguous text relating to"the method of the positive and the negative"and gives reasons supporting the interpretation provided here.Yang Hufs understanding of the concepts of"positive"and"negative"and his practice relating to these two concepts may easily be confused with their apparent counterparts in modem mathematics.Also,careful analysis of the mathematical methods in this work reveal that the order of problems in Yang Hufs Reclassifications of Mathematical Methods Explaining in Detail The Nine Chapters([Xiangjie jiuzhang suanfa zuanlei詳解九章算法纂類],namely,the last section of Mathematical Methods)were rearranged according to commentaries to specific methods that appear in Mathematical Methods.Some textual clues referring to the zzprevious question"(qianwen前問)in certain commentaries of Mathematical Methods indeed reflect the order of problems in Reclassifications.Yang Hui made especially detailed commentaries on the problems that he arranged in a sequence that differs with respect to the original order of problems as they appear in the ancient classic work,The Nine Chapters.All these discoveries reveal and serve to prove a close relationship between Yang Hufs Mathematical Methods and his Reclassifications.

Ultrasonic-assisted condensation of chitosan with salicylaldehyde

In order to synthesize an improved adsorbent for heavy metal ions,we studied the condensation reaction of chitosan with salicylaldehyde in ethanol to form a Schiff base.The effect irradiating the reaction using an ultrasonic liquid processor was contrasted with conventional methods.The IR spectra of condensed chitosan prepared by the two methods showed that their molecular structures were identical.The reaction conditions,including solvents,ultrasonic power density and irradiation time,pH,and reactant ratio,were optimized by orthogonal design.A shorter reaction time and a higher product yield were obtained using ultrasonic-assisted synthesis compared with the traditional method.A condensation degree of 89.63% was achieved using the optimized conditions:i.e.ultrasonic irradiation at 180 W for 60 min;95% ethanol as the solvent,pH 4.0,and salicylaldehyde:chitosan ratio of 6:1.

Simultaneous Determination of Six UV-Filters in Cosmetics by HPLC

A reversed-phase high performance liquid chromatographic method with diode-array detector was established to simultaneously determine the six UV-filters, isopentyl-4-methoxycinnamate, ethylhexyl methoxycinnamate, ethylhexyl salicylate, homosalate, butyloctyl salicylate and ethylhexyl triazone. They were separated on a Kromasil C18 column, with gradient elution by methanol and water, and detected by HPLC-DAD.All results demonstrated good linear relationship in proper mass concentration range. The limits of quantitation(LOQ) were between 0.5 and 1.25 mg/L. The recoveries of the six compounds ranged from 98.3% to 101.0% at two inrements with the relative standard deviation(RSD) no more than 1.5%.

First-order perturbation approximation for rock elastic moduli in transversely isotropic media

Seismic anisotropy is a relatively common seismic wave phenomenon in laminated sedimentary rocks such as shale and it can be used to investigate mechanical properties of such rocks and other geological materials. Young's modulus and Poisson's ratio are the most common mechanical properties determined in various rock engineering practices. Approximate and explicit equations are proposed for determining Young's modulus and Poisson's ratio in anisotropic rocks, in which the symmetry plane and symmetry axis of the anisotropy are derived from the constitutive equation of transversely isotropic rock. These equations are based on the media decomposition principle and seismic wave perturbation theory and their accuracy is tested on two sets of laboratory data. A strong correlation is found for Young's modulus in two principal directions and for Poisson's ratio along the symmetry plane. Further, there is an underprediction of Poisson's ratio along the symmetry axis, although the overall behavior follows the trend of the measured data. Tests on a real dataset show that it is necessary to account for anisotropy when characterizing rock mechanical properties of shale. The approximate equations can effectively estimate anisotropic Young's modulus and Poisson's ratio, both of which are critical rock mechanical data input for hydraulic fracturing engineering.
