telescope tube

For the load capacity of the mounting is limited, how to reduce the weight of the telescope tube is the crucial problem in the design.

由于EM-1赤道装置的承载能力有限，镜筒设计中如何降低重量成为设计的关键问题。

The static and dynamic radial load capacity and stiffness of the altitude bearing, the radial and torsional frequency of the optical tracking telescope tube can be calculated by this method from the bearing contact theory and suggested vibration model.

从轴承的接触理论和提出的振动模型所得到的计算方法，可以计算镜筒旋转轴支承的动、静力承载能力，支承刚度，镜筒的径向和扭转振动频率。

During 1982 to 1984, the LEST Foundation finished the possibility research, made a conceptional telescope design, carried out the experiments of helium filling and wind tunnel testing for the telescope tube and suggested a detailed financial budget with a total amount of 25 million US dollars.

自1982年到1984年，LEST基金会完成了可行性研究、方案设计，做了镜筒充氦和风洞试验，并提出了一个总额为2500万美元的财政预算。

Under this condition, the stray light of a Cassegrain telescope comes from diffuse reflection of telescope tube wall, directly reflected light by a horseshoe mirror, diffuse reflection light by secondary mirror mount and is symmetrically distributed.

在这种条件下，卡塞格伦望远镜系统杂散光成对称分布，主要来源于望远镜筒壁的漫反射光、马蹄镜的直接反射光和次镜支架的漫反射光。
