The control principle of electrostatic shaping was introduced according to the balance between electrostatic force and resulting force formed by membrane deformation and the complex shaping process of SMEC. Then, taking the trisection circularity electrode for an example, the distribution characteristic of electric potential in the electrostatic field was analyzed, namely, the expression of potential function in the electrostatic field was deduced by Laplacian equation. And then, by combining the difference equation with electric potential expression, the numerical solutions of electrostatic force in single electrode mode and trisection circularity electrode mode were disposed. Finally, the calculated figure was compared with the ideal paraboloid and comparison shows that more accuracy would be achieved by multi-electrode control.

根据静电力与薄膜变形载荷作用力之间的平衡关系和静电拉伸薄膜反射镜成形的复杂过程，介绍了薄膜反射镜静电成形的控制原理；以三等分环状电极为例，分析了静电场中空间电势分布特性，即从拉普拉斯方程推导出静态场势函数的表达式；然后，利用差分与电势方程结合的方法，对单电极电场力和三等分环状电极电场力进行了数值求解；最后，将计算面形与理想抛物面进行了比较，结果显示，单电极情况下得到的薄膜反射镜面形不是理想抛物面，若采用多电极控制可获得更高的控制精度。

Nanometer pearl powder creates the fourth times of pearl cosmetic----nanometer times. We select carefully limnetic pearl with high quality, adopt advanced super-sonic airstream physical manufacturing technic. Through super-sophisticated machine, we produce nanometer pearl powder with average diameterof 40-100 nanometer ( 1 millimeter = 1000000000 nanometer), equivalent to one hundredth of human body's pore, that is to say, by nanometer technic, we can powder one bead of pearl with 8 millimeter diameter into 64 trillion pieces, which means, everyone on the earth can have more than 10 thousand pieces.

纳米珍珠粉开创珍珠美容第四时代—纳米时代，我们精选优质淡水珍珠，采用先进的超音速气流物理粉碎技术，通过超精密设备生产出的平均粒径在40-100纳米（ 1 毫米＝ 1000000000纳米）左右的纳米级珍珠粉，细度只有人体毛孔的1/100，也就是是说将一颗直径8毫米的珍珠通过纳米技术粉碎等分，可粉碎为64万亿粒，相当于每个地球人都可以拿到1万多粒。

One set of securities, known as an equity tranche, pays the highest returns but is the first to suffer if the underlying bonds default; other securities offer a much lower yield but a triple-A credit rating, because a lot of defaults would be needed to trigger losses.

其中一套被称为"平等分额"可享受最高回报，但同时，如果优先债券欠债，这种债券也将首先遭受损失；其他一些债券，虽为3A级，但收益较低，因为引起损失的是大量的欠债。

Secondly, referring to the present study on the connotation of the medium-income group and its measurement of dividing, the paper puts forward the basis and method of the sexenary division of the citizens and defines of the medium-income group as a group of people whose income is just lower than the millionaire and billionaire, Similar to the "middle class" popular in the western countries in economy and politics. As tar as the measurement is concerned, the paper sets up the measurement considering both the quality and quantity on the basis of income. From the point of view of quality, the medium-incomes should be able to pay for the real estate, life-lone education, medical care and luxurious goods all or mostly by their personal income, inheritance or loan form banks. In addition, they should be capable of keeping their income rising steadily.

其次，结合当前学术界对中等收入者的内涵及其划分标准的研究现状，本文提出城乡居民六等分的依据和方法，将本文研究视野中的中等收入者概括为一类仅次于亿万富翁和百万富翁的高收入者，在经济特征上，类似于西方世界流行的&中产阶级&；在其划分标准上，确立了以收入作为划分不同群体的依据，衡量标准采用质与量相结合的方法，从质上看，中等收入者的收入应能全部或绝大部分通过借贷、继承等方式支付房产、教育、医疗、高档消费等支出，并具有可持续增长的收入能力。
