It was found that the heteropolar space charges in composites were more than those in pure LDPE; Field-induced-thermally-ionization appeared in microcomposite obviously.

本文采用电声脉冲法(Pulsed-electro-acoustic Method， PEA)研究了纯LDPE、不同浓度的Nano-SiOx/ LDPE和Micro-SiO2/ LDPE复合材料等在中等直流电场下(5-20kV/mm)的空间电荷分布。

This study was organized in three parts. Part One: The ecological study on the relationship between environmental organochloride pollution and the incidence rate of colorectal cancer. In this part, the incidence rate of colorectal cancer was determined from the tumor registry system of Jiashan County, a highest incidence area of colorectal cancer. The soil and rice samples were collected according to the incidence rate of colorectal cancer and the geographic position of the east, west, south, north and center. The concentrations of dichlorodiphenyltrichloroethane, hexachlorocyclohexane, polychlorinated biphenyl and sodium pentachlorophenate were detected in laboratory.

Heat value relates to lignose content and benzene-ethanol extractive content linearly.(3) Of all the 12 tree species,Schima superba, Castanopsis hystrix, Myrica rubra have the strongest resistance to fire; Machilus pauhoi, Mich elia macclurei, Mytilaria laosensis, Camellia olifera and Manglietia tenuipes are relatively strong in fire-resis tance, and Lithocapus thalassica, Tsoongiodendron odorum, Cunninghamia lanceolata and Pinus massoniana are weak in fire-resistance.

木质素含量和苯-乙醇抽取物与总发热量有线性相关关系；(3)由多目标决策方法对12种树的抗火性能综合排序，木荷、红椎、杨梅的抗火性强，刨花楠、水老排、火力楠、油茶和木莲的抗火性中等，稠木、观光木的抗火能力较弱，杉木、马尾松的抗火能力弱。

The research reveals that linguistic politeness in arguments in American courts shares great similarities with that in Chinese courts; negative politeness strategies are most frequently employed by lawyers, followed by positive politeness strategies and off record strategies.

This paper analyses the characteristics of urban system in Anhui Province. It is found that this region exhibits a city-size distribution following the rank-size rule. The urban primacy index is low, the scale effect is inevident, the urban scale is small in whole, the development of metropolis and big cites is not enough, medium-sized cities is prominent and the spatial distribution of cities is not equal.

运用统计数据，在深入分析的基础上，发现安徽省现状城市体系的等级规模结构呈位序—规模分布；城市首位度偏低，规模效应不明显；城市规模总体偏小，特大城市和大城市发育不足，中等城市突出；城市规模空间分布不均衡，区域分异明显。
