photon current meaning in English

光子流

The simulation program has been implemented to simulate the procedure of hxmt detecting x - ray source . the simulation result has been used to analyze the overlay region in celestial sphere , the variation of photon current intensity and the variation of the angle between sun and orbit , which demonstrate the reason why to select a 550 km height and 43o inclination low earth orbit as hxmt ' s orbit
利用仿真程序，实现了仿真一个正在预研的天文卫星? ?硬x射线调制望远镜hxmt观测x射线源的过程，分析了天球覆盖、 hxmt接收的光子流强度的变化和太阳轨道面夹角的变化，说明了选取高度为550km ，倾角43o的近地圆轨道作为hxmt的运行轨道是合理的选择。
