与此相反，美国的方法是在“美国193”降到足够低的轨道上之后再将其击毁，将可能对其他卫星造成的危险降到最小。
By contrast, the United States' approach was to fire on USA 193 when it reached a low enough orbit to minimize danger to other satellites.
本文分析了该算法中可能引起误差的环节，研究了造成误差大的条件，同时给出计算击毁概率的另一个算法。
In this paper the sources that may cause errors are analyzed, and the conditions leading to larger errors are investigated. An algorithm for the calculation of damage probability is proposed.
