查询词典 imperatively

The temperature gradient occurs imperatively and then influences to the image quality and resolution of the space camera. Based on the theory of optical wavefront error and combining the engineering practice, the thermal optical evaluation has been done to the optical window with non symmetric temperature field. The RMS wavefront errors of the optical window have been calculated on each typical position in orbit cycle.

文中结合工程实际，以光学波像差的基本理论为基础对空间相机光学窗口的非轴对称温度场进行了热光学评价，编程计算了空间相机光学窗口在一个轨道周期内各典型位置处的均方根波像差，并把计算结果与美国"天空实验室"光学窗口的相应数据进行比较，以验证本文热光学分析的合理性、正确性。

Modern social security system is imperatively enforced by state.Viewing thepractice of social security in each country,we can conclude that it can't depart fromlegality,that is,each country legalizes its policy and measure of social securitythrough legislation and accordingly carries them into execution nationwide from topto bottom.So legalization is the only road to the enforcement of social securitysystem.

现代社会保障制度是由国家强制实施的，从各国社会保障的实践看，社会保障制度离不开法制，也就是说，各国都是通过立法将社会保障的各项政策和措施法制化，才使它在全国范围内自上而下才使它在全国范围内自上而下地实施，因此，法制化是社会保障制度实施的必由之路。

In the chapter 2, the theoretic knowledge about the photosensitive resin and the grinding tools was firstly introduced.

第二章阐述了光固化树脂结合剂磨具的相关理论研究。

Do not use the program's indenting or margin-setting features; these will be added during typesetting.

不要使用缩排，页面边缘设置之类的选项，偶看不大懂。
