结果表明：一定条件下聚合物凝胶和疏水缔造合聚合物溶液具有相似的溶液结构和流动特性；胶态分散凝胶在多孔介质中的流动存在转变压力，2组流动实验中疏水缔合聚合物溶液也表现出类似的转变压力，分析认为聚合物凝胶分子链间的联结是化学交联，而疏水缔合聚合物为物理缔合，类似的分子链间联结方式是两种体系有相似流动特性的内在原因。

With the deepening of hydrophobic modification,the dispensability of modified starch in organic solvent liquid paraffin is markedly enhanced.

In addition, the membrane polarization time is gained from cell's simplified equivalent circuits and approved by system time constant of the state space equations of cell suspended system. Secondly, Laplace equations of the ideal model are built based on Faraday's Law, Gauss's Law, and charge conservation to analyze and calculate the amplitude and variation of transmembrane potential detailedly.

为了对微生物脉冲电场效应进行理论上的分析，首先，本文从细胞膜的结构、组成及功能入手，建立了微生物细胞的介电模型，求出了细胞膜的介质极化时间常数，并通过系统状态空间方程对其进行了验证。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
