一种求恒星视位置的新算法。
A new algorithm of calculating the apparent place of fixed star.
然后经过一系列空间坐标转换，将恒星视位置坐标统一转换到观测点坐标，得到恒星在指定时刻相对于观测者的视住置；
Then, the star visional coordinate is converted into the observation coordinate, and the star visional position is achieved in accordance with the observe at the named time.
