According to practical experience,the paper analyzed the factors to cause end breakage of small yarn package at the first floor of polyester POY post processing,put forward the control methods,which can improve production efficiency and quality.

根据生产实践的经验，分析造成涤纶POY后加工底层小卷丝断头的各种原因，提出减少POY后加工底层小卷丝断头的控制方法，从而提高后加工的生产效率和产品的质量。

Looking at it from an artistic perspective, although such exhibition in public spaces is indeed avant-garde, in actuality these uneducated, sloppily dressed, even filthy farmers can be found in every corner of the city, by the end of the 1990s they were already a reality visible everywhere.

二十世纪上半期的现实主义艺术为当时的底层社会建立了自己的话语权力，成为底层社会的代言人，并在之后成为一种平民主义的政治话语。

The results showed that the interface of the middle plough layer and plough sole under the present farming system was wavy type, while the interface of the plough layer and plough sole of the corn field under the cropping system of annual autumn plowing was flat type.

It indicates a social power, which is aliened fromthe mainstream of European society and subordinate to the social group. AntonioGramsci mainly concerned with the issues of bottom-class under the rule of his party.

底层这一概念最早来自于意大利马克思主义思想家葛兰西的《狱中札记》，是指一种革命力量，是指被排除在欧洲主流社会之外的处于从属地位的社会群体，葛兰西所关注的是底层在自己的政党领导下取得霸权的问题。

At the same time, the term "subaltern" is politically incorrect in the sense that it allows the general public to be indifferent to subaltern groups, taking for granted their suffering condition. In other words, subaltern is a term that recognizes the existence of inequality and fixates such concept on people's mind.

但是&底层&也是一个政治不正确的称呼，因为这个词容易让人们对底层人群的境遇心安理得、无动于衷，换句话说，这是一个承认了事实不平等的词，并把这种不平等在观念上固定了下来。

Example two analyzes the static construction character steel frame, braced frame and different braced frame, including relation of loading-level displacement, inter梥tory displacement and distribution of plastic hinge, the frames ductility, the axis force of brace and shearing-force of ground brace bearing, then it is clearly known the brace can minis the level displacement of frame, minis inter-story displacement, bear ground floor shearing-force. So, the brace greatly inflects construction performance of braced frame .

算例二对纯框架和支撑框架以及支撑框架不同支撑情况下进行非线性弹塑性分析：包括荷载—水平位移关系，层间相对位移与塑性铰分布，刚架延性，支撑轴力及底层支撑承担剪力等情况，了解到支撑可以减小框架柱顶水平位移，减小层间相对位移，增加刚架延性、承担底层剪力，显示支撑对框架结构性能的重要影响。

Through carrying on nitrifying potentiality dynamics analysis of the substrate artificial medium in the ecological floating bed, find substrate artificial medium nitrifies approximate to be zero response. the dynamics equation is y =-0.1347x+4.3542, the artificial medium nitrifying potentiality is 3.4×10-5g/h·slice.

通过对生态浮床底层人工介质的反硝化潜力进行动力学分析，发现底层人工介质的反硝化近似为零级反应，动力学方程为y=-0.1347x+4.3542，人工介质反硝化潜力为3.4×10~(-5)g/h·片。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
