Glyphosate brought the biggest vice-effects, clethodim took the second and fenoxaprop-p-ethyake minimum:(1)As to the pure growth, MDA accumulation, the relative permeability of plasma membrane and chlorophyll content, glyphosate had evident influences on them in the daily dosage, 1/2 and 1/4 of the daily dosage . The walnut seedling dried and died twenty days later.(2)The influences of clethodim in different concentration such as double daily dosage, daily dosage and 1/2 of daily dosage on the above four indexes demonstrated differently, the more concentration was, the more severe the influence. was. With the concentration reducing, the influence weakened gradually.(3) Double daily dosage, daily dosage and 1/2 daily dosage of fenoxaprop-p-ethy exerted a slight vice-influence to the MDA accumulation, the relative permeability of plasma membrane and chlorophyll content.

1用草甘膦常用量、1/2倍常用量、1/4倍常用量处理之后，对核桃苗新梢生长量、叶片中丙二醛含量、膜相对透性以及叶片中叶绿素含量的影响最大，几乎所有样枝的新梢在药后20天后都发生干枯及死亡现象；(2)用收乐通2倍常用量、常用量、1/2倍常用量处理之后，对核桃苗的新梢生长量、叶片中丙二醛含量、膜相对透性及叶片中叶绿素含量的影响，呈现出浓度不同影响亦不同的现象，浓度越大，影响越明显，随着浓度的降低，影响也逐渐减弱；(3)用威霸2倍常用量、常用量、1/2倍常用量处理之后，对核桃苗新梢生长量、叶片中丙二醛含量、膜相对透性及叶片中叶绿素含量的影响最小；(4)三种除草剂对核桃苗的影响随着药后时间的延长，其影响在逐渐减小。

The surface hydroxyl group onto magnetic polyvinyl acetate nanoparticles can be obtained by saponification reaction on their surface.

结果表明，磁性聚苯乙烯颗粒与丁二酸酐发生Freidel-Crafts酰基化反应，可以在颗粒表面引入少量羧基；磁性聚甲基丙烯酸甲酯颗粒分别与乙二醇、二缩三乙二醇、聚乙二醇等发生醇-酯交换反应，可以在颗粒表面接枝不同分子链长度的末端羟基；磁性聚醋酸乙烯酯颗粒经过醇解或皂化反应可以获得表面羟基；磁性聚丙烯酸甲酯颗粒通过乙二胺或1，6己二胺的胺解反应可以得到表面氨基，继而与一氯乙酸反应可以引入亚胺二乙酸基团。

聚伞花序主要在分枝的轴上，3或者4二歧分枝，分枝纤细和开展；花序梗1-2厘米，副花梗5-15毫米；非常短的花梗，少于长约3毫米或无。

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.
