防雷工程是一项系统工程，要求将外部防雷装置和内部防雷装置统一考虑，着眼于全方位的雷电综合防护，把机房建筑物的防雷、雷电电磁脉冲（LEMP）防护、设备防雷、电源系统防雷、线路防雷、接地系统、保护装置等综合因素考虑在内。任何方面的遗漏带来的危害都是不能(Mine is a systems engineering project, requiring the external and internal lightning protection lightning protection devices to consider a unified, integrated focus on the full range of lightning protection, lightning protection of buildings to the engine room, lightning electromagnetic pulse (LEMP) protection, equipment, anti- Thunder, lightning protection power system, line lightning protection, grounding systems, protective devices and other comprehensive factors into account. Omission of any harm is not)

A forward Euler method has been implemented and a simple differential equation solved to compare the performance of the Euler method with Runge-Kutta method.

Particle swarm optimization has been used to solve many optimization problems since it was proposed by Kennedy and Eberhart in 1995 [4]. After that, they published one book [9] and several papers on this topic [5][7][13][15], one of which did a study on its performance using four nonlinear functions adopted as a benchmark by many researchers in this area [14]. In PSO, each particle moves in the search space with a velocity according to its own previous best solution and its group’s previous best solution. The dimension of the search space can be any positive integer.
