用悬滴汽相扩散法生长了从产碱菌中分离纯化得到的麦芽四糖淀粉酶的晶体，并在MarRe search面探测器上收集了一套2.7埃分辨率的衍射强度数据。

It is important to study the influence of the detector number of wave band and the position of the wave bands on the result and analysis the aberrance degree of scanning image aroused by the changement of the parameter.

在产生遥感图像几何畸变的各因素中，系统扫描特性引起的畸变可以根据其规律形成独立的模块来处理。

In view of the facts that traditional graphical construction has less pertinence to stray light and tracing different incidence angle rays is fatiguesome and more likely to omit some rays, we proposed a reverse ray-trace method based on the ray reversibility. According to the method, a dot-matrix source was set at the image plane. Each dot emitted rays to fully cover the system aperture. A detector surface, large enough to receive all possible rays from the source, was set at object plane.

针对传统作图法设计遮光罩的针对性不强，且追迹不同入射角的光线繁琐、容易遗漏的问题，本文提出一种逆向追迹法，依据光的可逆性，在像面处设置点阵面光源，每一点都发出充满系统孔径的光束，在物面设置足够大的探测面，使之有充足的余量记录所有到达物方的光线，利用该方法可以在探测面上直观地区分出非成像杂散光。

Such a telescope does not need any thermal control as its behaviour under homogeneous temperature changes is perfectly homothetic and thus keeps the image focused onto the detector.

这样的一个望远镜结构不需要任何的温度控制，因为在均匀的温度变化下热形变也是一致的，可以保证图像在探测器件上维持聚焦。
