Then threekind of hard X-ray space telescopes, namely the collimator, the rotating col-limator and coded aperture mask telescopes, are introduced. Finally the softX-ray imaging telescope is introduced.

然后分别介绍了三种类型的硬X射线空间望远镜，包括准直型、旋转调制型和编码孔径型望远镜，最后简略介绍掠入射型软X射线成像望远镜。

Although the production of relatively small achromatic and apochromatic refractor telescopes of up to 15cm, and catadioptic systems of up to 18cm, all with a variety of accessories at Jena would continue until 1994 when it was realized that Zeiss could not compete in the world market; the Zeiss "APQ" refractor telescopes optics were among the finest in the world but the inability to Zeiss to adapt these products promptly to the realities of a free marketplace assured their demise.

虽然耶拿厂可以生产相对小点口径的消色差和复消色差折射望远镜（口径最大可达15cm），还有口径最大可达18cm的反射折射望远镜系统，而且产品规格类型丰富，但蔡司在1994年还是意识到，不能在此类产品的世界市场上继续竞争了；蔡司的"APQ"系列折射望远镜产品确实属于世界顶级产品之列，但蔡司不具备在自由市场经济环境下，迅速调整改进此类产品的能力，所以决定此类产品停产。

Eventually, propinquity of spacecraft to the Sun plus improvements of space solar telescopes in spatial, temporal and frequency domains may allow such space solar telescopes to take over completely, perhaps adding to observations of distant stellar coronas to explain the coronal-heating problem.

最终，太阳观测卫星直接抵近观测并且会有先进的空间望远镜加入这个队伍，以后空间太阳望远镜将完全承担任务，然而对远距离星体日冕的观测同样也能解释日冕加热的问题。

Radio telescopes have been able to probe space beyond the range of ordinary optical telescopes.

射电望远镜已能探测普通光学望远镜达的宇宙空间。

Radio telescopes HAs be able to probe space beyond the range of ordinary optical telescopes.

射电望远镜已能探测普通光学望远镜达不到的宇宙空间。

In this paper, the effects of the rigid body motions and low frequency surface errors on the image quality were analyzed. Quadratic equations were used to build the mathematical model of the Wolter type I and II X-ray telescopes and reduce the computational complexity of ray tracing. With the help of a self-developed optical surface analysis code, the effects of the perturbations of the mirrors on the image quality was analyzed and the growth of the image spot formed by deformed telescopes was calculated, this is important for giving the reasonable fabrication tolerance.

在本篇文章中，详细分析了刚体运动误差和低频表面误差对成像质量的影响；使用空间解析几何学的二次曲面方程建立Wolter I、II型X射线掠入射望远镜镜片的数学模型，降低光线追踪的计算复杂度；借助自主开发的光学仿真软件分析了国内研制的X射线成像望远镜的刚体运动误差和低频表面误差对成像质量的影响，计算出像点艾里斑半径均方根值随误差变化的增长率，对工程上提出合理的制造公差的误差容限有重要的指导意义。

When the bandage telescopes down the limb of the dog it may bunch up and abrade the limb.

当绷带望远镜下来肢体的狗，它可以集中和研磨肢体。

Radio telescopes are relatively inexpensive; radio signals travel at the speed of light, faster than which nothing can go; and the use of radio for communication is not a short-sighted or anthropocentric activity.

射电望远镜相对来说是昂贵的，无线电信号以光速行驶，没有什么比起它能走的更快了；而且无线电对于传播的使用不是一种短视或者以人类为宇宙中心的行为。

Takahashi also makes observatory telescopes which include: 350mm hyperbolic astrographs, 300 and 400mm Cassegrains, 200, 250 and 300mm triplet apochromatic refractors and the large EM-3500 mounts to carry them.
