Many API functions are used in my paper in order to control the keyboard and the mouse of the remote computer, and also control its system ability. The monitor can control registry of the remote computer by TRegistry and obtain its system information by registry. The journal hook is also setted to record keyboards input information. I also make chat system and media play based on the stream. The server can capture screen images of remote computer and transported by the stream to the monitor, so we can monitor it in time.

For non-intense beams,particle trajectory can be obtained by multiplying linear transport matrices. For nonlinear transport of intense beams,the influence of space-charge effect on beam transport needs to be taken into account,and self-consistent solution should be derived because of the interaction between charged particle distribution and space charge field. In the program,components and currents are divided into equal intervals,respectively,and each interval is treated as a uniform solenoid field.

程序在计算非强流脉冲束流的线性传输时，粒子的轨迹通过矩阵的直接相乘计算得出；程序在计算强流脉冲束流的非线性传输时，需要考虑束流中的空间电荷效应对束流传输的影响，在束流运动过程中，空间电荷场也在不断地变化，而且粒子运动的轨迹与空间电荷势又是相互依赖的，因此需要求得一个自洽的解，先把元件分成若干均等的区间，把电流分成若干等份，后采用束流电流迭代与元件区间迭代的计算方法。
