空间太阳能电站还能带来多重附加价值:一是给卫星减负,使其摆脱庞大笨重的太阳翼(帆),换上小巧的接收天线,从“太空充电桩”获取电力,显著提升灵活性和续航能力;二是实现能量和信息双传输,让通信、导航卫星的天线同时具备接收电力的功能;三是优化太空信息处理,在太空直接完成数据处理,避免当前“太空压缩、天地传输、地面解压”模式带来的丢包、失真等问题;四是为月球基地、火星前哨站等深空探测设施提供远程无线供电。
When one of the input cells changes, all the cells that depend on it need to react to that change — the aforementioned reactivity. In practice, though, this is the bare minimum requirement. When building reactive systems, there are usually some additional requirements we impose that make the problem harder:

MuJS was designed with a focus on small size, correctness, and simplicity. It is written in portable C and implements ECMAScript as specified by ECMA-262. The interface for binding with native code is designed to be as simple as possible to use, and is very similar to Lua. There is no need to interact with byzantine C++ template mechanisms, or worry about marking and unmarking garbage collection roots, or wrestle with obscure build systems.
