在Perona和Malik的各项异性扩散方程的消噪模型中，一些小梯度的细节信息和噪声会被扩散掉，而在这些细节信息点往往具有零高斯曲率的特征，根据这一特点，对PM模型加以改进。

In these programs, the author stores the non—zero elements of the global stiffness matrix in line, and solve the equations using Gauss—Seidel Method, which can not only save numerous internal spaces, so it improves the ability to deal with the giant engineering problem greatly, but also promote the efficiency to solve the equations.

本文作者独立编制了三维弹性损伤有限元程序，该程序采用一维索引压缩存贮整体刚度矩阵配合松驰法解方程，既大大节省了计算机内存从而为扩大解题规模提供了可能，同时又提高了解题效率。

One-dimensional time domain helicopter-borne electromagnetic responses are computed using G-S transform and Gauss numerical integral. The variation of electromagnetic responses due to bird height is analyzed, and then the variation of bird height is transformed to the variation of pseudo-layer thickness of zero conductivity to eliminate the error of the altimeter.

First, when the Pythagoreans discovered the irrationality of the square root of two … Second, when the philosophical Bishop, Berkeley the Bear, pointed out the contradiction of dividing by zero … But Cantor the Goat, by his General Set Theory, has shown us how to resolve these problems, and to dispel crisis from the Foundations of Mathematics!

每一次危机是毕达哥拉斯学派发现了2的平方根是一个无理数……第二次危机是作为哲学家的毕晓普这只贝克莱大熊指出了用0做除数所具有的矛盾性……而康托尔山羊在它的《普通集合论》里向我们证明了它是如何解决这个问题的，并且消除了数学基础的危机！
