From the reform and open to the outside world,the civic consciousness in our country has developed fully,but it still can not adapt the current development of the market economy.Especially in the rural area, the civic consciousness of our country's peasants restricts the fast development of rural market economy to a large extent.Consequently,it is a great significance to cultivate the peasants' civic consciousness.This paper discusses some opinions in this field,In detail:The first part starts with the concept of the civilians and the civic consciousness,and mainly discusses what are the civilians and its historical development.Then the paper analyzes the meanings of the civic consciousness and its formation conditions,and based on which analyses the characteristics of the contemporary peasants in our country and its influence on the formation of our country's civic consciousness.At present,the lifestyle of our country's peasants is mainly agricultural.They are the subordinate to the dominant in the field of the political right,possess the low quality in the whole in the cultural aspect and relatively lag behind in the aspect of ideology.All hinder the development of the peasants' civic consciousness,affect the enlargement of the peasants' political participation,and go against the cultivation of the peasants' collective consciousness.

改革开放以来我国公民的公民意识得到了长足的发展，但仍然不能适应当前市场经济的发展，尤其是在农村，我国农民的公民意识在很大程度上制约了农村市场经济的快速发展，因此，培育农民的公民意识具有重要意义，本文即是想在这方面谈谈自己的想法，具体来说：本文的第一部分首先从公民和公民意识的概念入手，主要论述了公民意识的形成及其在我国的历史发展，接着进一步的分析了公民意识的含义及其构成，在此基础上分析了当代我国农民的特点以及其对我国农民公民意识的生成所产生的影响，当前，我国农民在生存方式上，仍以农业为主，在政治权利方面，仍是权势力量的从属者，在文化素质方面，整体素质仍然偏低，思想观念方面还是相对落后的，这些特征在很大程度上阻碍了农民的主体意识的发展，影响了农民政治参与的扩大，不利于农民公共精神的培养。

A new method was proposed by imposing a rotating electromagnetic field during horizontal continuous casting of thin-walled cupronickel tube billets. The effects of electromagnetic field on the surface quality, solidification structure and mechanical properties were investigated experimentally by use of BFe10-1-1 alloy.

摘 要：为获得高质量的薄壁白铜管坯，提出了在水平连铸过程中施加旋转电磁场的管坯连铸新方法，并采用BFe10-1-1合金进行实验，考察了电磁场对白铜管坯表面质量、凝固组织和力学性能的影响。

First,image structure vector field is derived from source luminance orthonormal vector sets. Andusing neighbor vectors to improve the weak gradient fields produces the structure vectorfield that is needed by LIC rendering. Then, LIC convolution step-length is adjustedaccording to local curvature in the structure vector field. LIC convolution length iscalculated according to the local statistical characteristics of the texture image. Finally, thealgorithm transfers the reference image\'s color characteristics to the rendering result tomake it full of rich color like oil paintings.

该算法通过计算源图像亮度分量的切矢量产生图像的结构矢量场，并对弱矢量区域进行邻域填充处理，获得LIC绘制所需的结构矢量场；然后，根据结构矢量场的局部曲率特征调整LIC的积分步长，并根据纹理参考图像的局部统计特征，自适应地改变LIC的积分长度；最后，将颜色传输算法引入LIC绘制结果，对绘制效果颜色进行渲染。

There isn"t obvious selectivity in blank cutworm imperilment, the onseting quantity and imperilling degree is similar on different crops. It"s more serious in the field of invasion of weeds and corn intercrop potato than single cropping of corn, and the field of forecrop green manure is more serious than single cropping. Imperilment degree of black cutworm is very serious in both high altitude region as Dewu (1780 meters) and low altitude region as Lemin (1450 meters). The imperilment degree in two regions have no obvious differences. 4. The imperilment of second generation armyworm is very serious in both high altitude region of Dewu and low altitude of Lemen town.
