税费改革后乡镇财政运行的困境与对策

农村税费改革对乡镇财政收入的消减效应明显,对增加乡镇财政收入的替代效应较弱;农村税费改革使乡镇财政困难等原有问题充分暴露出来,进一步扩大了乡镇财政的不平衡,使乡镇财政正常运转更加困难;要使乡镇财政走向良性运转轨道,就必须完善地方财政管理体制,完善财务管理机制,加大力度培植乡镇税源,转变乡镇政府职能,建立合理的公共管理体制。     

Problem of the free oscillations of a capillary bridge

The free oscillations of a capillary bridge whose equilibrium shape is determined by the surface tension forces and the static gravity field are investigated. The values of 25 “lower” levels of the spectrum of natural oscillations of the capillary bridge are found for various control parameters in accordance with the experimental conditions.     

Voltammetric determination of mesotrione at hanging mercury drop electrode

A study of the electrochemical reduction of the mesotrione pesticide on a hanging mercury drop electrode (HMDE) was performed as a basis for the development of a sensitive analytical method for natural samples. The electrochemical characteristics of herbicide mesotrione dissolved in a phosphate buffer (pH 7.0) have been determined by means of electrochemical techniques such as cyclic voltammetry (CV) and differential pulse voltammetry (DPV) over a wide range of pH from 2.0 to 10.0. The experimental parameters, such as electrolyte type and its pH, pulse amplitude, and scan rate were optimized. The method was applied to the determination of the pesticide in a spiked soil samples. Using this method, a linear calibration curve for mesotrione was obtained up to the 0.1 μM range in pH 7 phosphate buffer solution with a detection limit (S/N = 3) of 50 nM. The method can be applied successfully to the determination of mesotrione in soils. The text was submitted by the authors in English.

对英语专业八级口语口译考试评分的探讨

本文通过对英语专业八级口语口译考试的评分标准的考察，指出八级口语口译考试评分中两个突出的特点，即突出口语考试和口译考试评分“信息单元化”，从而影响口译质量评估的有效性。适当改变评分比例和口译评分标准的改进将有助于改善测评效果。     

A Novel Approach for Entrapment of Biopolymers in Silica Matrix by Sol-gel Technique

1 Results The entrapment of biopolymers into silica by the sol-gel technique meets with incompatibility of inorganic and bioorganic components. The aim was to develop a compatible procedure biomimicking the biomineralization processes in the living nature. A suggested solution in Ref.[1-2] for the biopolymer entrapment into silica matrix is based on a novel silica precursor. The developed approach is distinguished from the common technique for fabrication of hybrid biopolymer-silica nanocomposite materi...

论国家对农民工群体的政策缺失

伴随着国家城市化和工业化进程的加快，农民工成为一个越来越受人们关注的群体。在我国以户籍制为基础的城乡二元结构下，农民工有着非常复杂的身份，他们生活、工作并居住在城市，但是他们的户籍在农村。在我国，社会福利保障制度是以户籍制为基础划分的，这样特殊的背景导致了农民工群体在很多方面被排除在社会福利保障制度之外。目前，我国正在积极构建社会主义和谐社会，在这个大背景的感召下，农民工群体作为和谐社会的一个特殊群体，对他们的社会政策有待进一步完善。本文分析了农民工群体在医疗保险、用工制度、子女教育等方面的政策缺失，并提出了相应的政策建议。
