In order to meet the design requirements of a Long Slit Spectrograph worked at the World Space Observatory,the LSS primary structure was designed and a structure optimization method for the LSS primary structure was studied.

为了满足世界空间紫外天文台中的有效载荷长缝光谱仪的设计要求，设计了LSS主结构并对主结构的优化设计方法进行了研究。

At present,this apparatus is used mainly for the examination of the perfectness of convergent spherical wave surface with aperture angle≤1:3,hence it can be used for the non-contact direct test of aluminized or unaluminized concave mirrors with any ...

因此可以用来无接触的直接检验任意口径的镀铝或未镀铝的凹球面镜；加入辅助镜后可以检验平面镜、天文望远镜用的各种非球面镜、介质的均匀性、光学系统的质量、光轴校正及安装变形情况；也可给出物镜对于现用激光波长(6328)的波面差及测出某些象差。

The main branches of a spherical astronomy, practical astronomy, astronomy and astronomical azimuth geodynamics.

主要的分支学科有球面天文学、实用天文学、方位天文学和天文地球动力学。

It thinks that Complete Principle of Measurement inherited the Writing Style of Elements. Secondly, it is taken out five key parts——plane geometry, solid geometry, conic, spherical trigonometry and spherical astronomy part——to comprehend. The main contents of mathematics and astronomy involved in Complete Principle of Measurement have been set up respectively in accordance with the characteristics of their subject.

其次，又按照学科分布从中抽出平面几何、立体几何、圆锥曲线、球面三角和球面天文等五部分内容进行重点解读，认为《测量全义》中所涉及到的主要数学和天文学内容已经按照学科特点分别形成和建立起来，为后来西学的进一步传播做出了贡献。

It is the study of the use of spherical coordinates to determine how the objects projected on the celestial sphere depending on the location, and study these changes depending on location laws and causes, offered to time depending on location of celestial calculation of parameters of the basis and method, as all the astronomical observations necessary for the basics, the main means of spherical trigonometry math and matrix operations.

它所研究的是怎样利用球面坐标确定天体投影在天球上的视位置，并研究这些视位置变化的规律和产生原因，提出以时间为参数的计算天体视位置的依据和方法，成为一切天文观测所必需的基础知识，主要的数学手段是球面三角学和矩阵运算。

Astronomical Observatory of software, according to the location at any time lovers accurately locate and predict the future Star Chart.

详细说明：天文观测软件，可以根据爱好者所在地点随时准确地进行定位并预测未来星空图。

Even the major astronomical research were also dependent on the complexity of computer operations can be the star map, how could it have been Mrs.

连专业天文研究人员也得依赖电脑的复杂运算才能得到的星图，怎么可能被希尔太太掌握呢？

Including screensavers and Web features, Stargaze will keep spaceheads happy and entranced for hours, and convert the unbelievers.

包括屏保和Web特性，StarGaze会带给天文爱好者持续的欢乐，并转变那些对此持怀疑论者，进入太空的世界。

An amateur stargazer in Australia spotted the impression last Sunday.

澳大利亚的一名业余天文爱好者在上星期天就获得的印象。

Even you are working, a student or a child, we welcome every stargazer and astronomy lover to join us.

本会欢迎每一位天文爱好者参加，不论是在职人士、中学生、甚至是小朋友。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
