查询词典 plane geometry

Through studying the math model and "man- plane-environment" operation system model, we analysed the usage range and virtues and defects of transmitting function model of human, optimal con- trol model and fuzzy control model;After analysing "man-plane-environment" operation system, com- puter simulation, we put forward the man- plane -enviroment operation system computer simula- tion evaluation system to determine the best match between pilot and plane.

摘 要：通过对人-飞机-环境模拟仿真技术中人操作者的数学模型及&人-飞机-环境&操纵系统的数学模型的研究，具体分析了人的传递函数模型、最佳控制模型、模糊控制模型的适用范围及优缺点，并在对&人-飞机-环境&操纵系统的数学模型、性能指标进行分析后，提出了确定驾驶员和飞机之间最佳匹配的&人-飞机-环境&操纵系统计算机模拟综合评估系统，从而使人们一开始设计飞机时就考虑驾驶员作用，减少设计盲目性，缩短设计周期。

According to the principle of the diameter of a circle corresponding to the right angle and the principle of short side for little angle in right triangle, projecting the initially-chosen point to the hyper-planes of the linear equation group in which every linear equation can be regarded as a hyper-plane and the projection points can be obtained. The initially-chosen point, and one arbitrary projection point, and the solution point are all on the surface of the relative hyper-geometry ball, therein-to, there is a projection point which is nearest to the solution point and it can be regarded as the next iterative initially-chosen point, so the solution problem of the linear equation group can be changed as an iterative problem of approaching the solution on the surface of a hyper-geometry ball.

根据直径对应的圆周角足直角以及直角三角形中短边对小角的原理进一步知道，当将初始点向线性方程组中各个方程所代表的超平面上投影得到投影点时，初始点和其任何一个投影点及方程组的解点都将位于一个相应的超球面上，其中必定存在一个投影点离问题解点的距离最短，即把该点作为下一次迭代的初始点，从而可将线性方程组求解的问题变成球面上逼近解点的迭代问题。
