说明：  三体问题粒子轨迹图。设正电荷在（-1，0）（1，0）处，电子初始位置根据设定。(three body problem. Positive particle is placed on （-1，0）（1，0）. This program will give the trace of the electron under selected initial position.)

说明：  微电网的提出旨在实现分布式电源的灵活、高效应用，解决数量庞大、形式多样的分布式电源并网问题 。 开发和延伸微电网能够充分促进分布式电源与可再生能源的大规模接入，实现对负荷多种能源形式的高可靠供给，是实现主动式配电网的一种有效方式，使传统电网向智能电网过渡。(The purpose of micro grid is to realize the flexible and efficient application of distributed power, and to solve the problem of large number and various forms of distributed power grid connection. The development and extension of micro grid can fully promote the large-scale access of distributed power and renewable energy, and realize the high reliable supply of various energy forms of load. It is an effective way to realize the active distribution network, and make the traditional power grid transition to the smart grid.)
