But with either telescope it was very impressive, particularly with the Cassegrain.

同样用天文望远镜，许多明亮的小星星和有明确形状的朦胧的"雾"都能清楚地的看到，特别是用卡赛格林式望远镜。

Manufacture of big aperture lightweight paraboloidal mirror is one of the key techniques for the research of the Cassegrain optical system.

研制某卡塞格林光学系统的关键技术之一是通光口径超过1000mm的轻质抛物面主反射镜。该反射镜相对口径为1/2，减重率为65%，是目前国内最大口径的轻质非球面反射镜。

Then with the intensity distribution being the optimization criterion,a new effective optimum way to design the structure of the Cassegrain reflective system is introduced here.

据此，本文提出了以该衍射效应作为卡塞格林反射系统结构优化设计的目标函数，该方法具有直观和量化的优点。

The results of the design show that DOE has a great effect on ameliorating the field of view of the Cassegrain optical system. The design scheme reduces the demand fur high technical levels and cost, and has a compact structure and better aberration char acter.

设计结果表明，衍射光学元件对于改善卡塞格林系统的视场具有重要的作用，此设计方案降低了对加工工艺的要求，大大降低了成本，结构紧凑且具有良好的消像差特性。

Because the coupling condition of NNGFM arises from the net current continuity imposed at the volume element interfaces, the relatively complex conversion formulation for partial current continuity condition of NGFM is unnecessary when applying G. E. T., and computation time is saved. The coefficient matrix of the coupled equations is tridiagonal, so it can be solved by forward elimination and backward substitution method.

NNGFM的基准校验及在大庆200MW核供热堆(NHR-200)上的应用表明，NNGFM计算精度和速度与第三类边界条件格林函数节块法NGFM〓相当，在相同精度下速度比CITATION能快1000倍；NNGFM给出的本征值、功率分布较NNGFM误差能减少一半以上，为更精确计算工作期、卡棒当量提供了条件。

And the intensity distribution in the focal plane is calculated with the ray tracing of finite element.

本文对卡塞格林系统在焦平面上的衍射效应进行了分析，并采用有限元素光线追踪法对衍射效应进行了计算。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
