Likewise,the axile potential and intensity of the system were calculated by Gauss elimination method and cubic spline interpolation.Furthermore,the electronic trajectory was traced by the changing steps Runge-Kutta method,the final size of e-beam about anode was true of demand.

在此基础上，通过Gauss消元法和三次样条插值法等解得了系统对称轴上电位分布以及内部场强分布，并利用四阶Runge-Kutta法追踪了电子从阴极开始到阳极入口处的运动轨迹且得到了合适的束斑大小。

The Franciscan Niccolo' da Poggibonsi visited the Holy Land between 1346-1350 and spent four months serving at the Holy Sepulchre. In his "A voyage beyond the Seas" describes the situation within the Holy Sepulchre:"Desirous am I to tell you about the altars, which are inside, and which are in all XX (20): for each generation of Christians has there its own altar. On Olive Sunday and Holy Easter all go there, each generation to its own priest, and each priest celebrates at the high altar..".

西元1364-1350年，方济各会士（NicColo'da Poggihonsi）造访圣地四个月，在那儿施行圣事，他的著作："越洋之旅"里描写了圣地的状况："我热切地要告诉你们"圣地内共有二十座祭台，所有不同年份的基督徒各有己属的祭台，圣枝主日和复活主日，信徒满堂，各年份的成员有己属的神长司祭，他证实圣墓∕复活大殿是的财产。

In Chapter 4, A detailed comparison between the realization of Cholesky decomposition and OR method is given, a systolic/wavefront array made of general purpose DSP is used to realize the adaptive beamforming at a moderate speed, and a wavefront array to extract the adaptive weights which is necessary in some applications is designed. In Chapter 5, the author proposed a new structure to realize the space time adaptive processing. First 1~q using the FFr and the truncating infinite sequence and sone optimizing method, a much simpler architecture can be acquired in realizing the three portion of channel processing: quadrature sampling, pulse compression and adaptive equalization.

第五章研究并提出了用全通用DSP模块设计空时二维自适应信号处理机的新方案，首先用快速付立叶变换和对长序列截断处理的重叠保留法以大大减少的运算量完成了处理机通道处理部分的正交插值、脉压、自适应均衡三个功能块的长阶数线性卷积运算，接着对自适应波束形成提出了多种实现方案，分析了多种方案下的运算量和设备要求，指出在不同通道数、不同数据吞吐率、不同自适应要求时这几种方案有不同的可行度和实现难度，并针对实际要求确定了一种运算田N、的实现方案，对自适应波束合成部分的大量贝玉以良元组咸肋冈络结拘和处凰闺和羽凶挝娠昨了优化设计以威少设备复杂性，构成了设备量大夕父伯小、们g团回高、辜于生回阴田闩引愧快的空时二维自适囱戏升引毗四机。
