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。

Eight 3×3 Kirsch direction templates are convoluted with a SAR image respectively and the maximum of convoluting results is used as the edge strength value of the central pixel in the window. The output gray level of the central pixel is the weighted average of gray levels of its eight neighboring pixels, and the weighting coefficients are corresponding edge strength values.

该方法利用8个3×3的Kirsch方向模板分别与SAR图像进行卷积运算，取其中的最大值作为窗口中心像素的边缘强度值，中心像素灰度值的滤波输出为它的8个邻域像素灰度值的加权平均，加权系数为每个像素的边缘强度值。

My love, I can feel you everywhere, encircling me like sunshine, breeze, sky, and ocean.

我的爱人，他无处不在，就像阳光，就像微风，就像天空，就像海洋，把我，轻轻的包围，可是，我却是多么、多么的傻，多么、多么的笨呀，因为，我不知道，不知道，自己的爱人他呀是谁

As spring thunders, it arouse patriotism of the people; as seeds, it gestates great spirits of love for the nation, advancement, democracy and science; as a monument, it condenses the source of the development and progress of the Chinese nation; as a clarion, it plays a grand theme song of the times.

她像春雷，唤起人民伟大的爱国意识；她像种子，孕育了爱国、进步、民主、科学的伟大精神；她像丰碑，凝聚着中华民族发展和进步的源泉；她像号角，奏出浩气长存的时代壮歌。

I can feel the blackness of every male taking root within my body, palpitating my soul.

如果有人问我，我会说，当晚上一个人独处房间，当把灯光熄灭，点起菸，你可以听见一些些微弱的声音，那像男人的喘息，像呻吟，像翻身床垫发出的声音，而你的毛孔将会放大，你可以感觉的到那黑色的雨从身体里流出，在每一个汗毛之间流动，从每一个毛细孔里流了出来，那是他的柑橘调香水，那是他汗湿的背心，那是他黏滑的体液，我可以感觉到每个男人的黑，在我体内扎根，在我灵魂里磨擦，当你发现自己再也不是一片白水而是阵黑雨，你会发现自己的生命像颗地球，在黑雨的沾染中温室化，在整片的火海中失去温度，你只能尖叫，发现自己的身体早已不是自己，被别人的回忆与习性占满而崩毁，世界只剩满满的无法忘怀与不能割舍，只剩下找寻另一个相似物另一个填充另一片黑雨，没有人逃的过这场浩劫，上帝终要人们复杂的互相侵蚀，在最后消灭回归。
