Average annual precipitation data of the last 30 years from 1961 to 1990 at 186 meteorological stations in Gansu and its nearby regions was compared and analyzed by Inverse distance weight tension, Spline, Ordinary Kiging methods. The result showed that the three interpolators could reflect the spatial distribution of precipitation of Gansu province. Ordinary Kriging method was the most effective, followed by Spline methods and Inverse distance weight tension method.

利用甘肃及其周边186个气象台站30年平均降水资料，分别采用了反距离加权法(In-verse distance weight tension)、样条函数法和普通克里格法等3种常见的空间内插方法较为系统的分析比较了这3种内插方法插值结果，结果表明：3种方法的结果都基本上反映了甘肃降水大体空间分布规律，而普通克里格法的插值效果最好，样条函数法次之，反距离加权法较差。

To overcome target expansion, shape transformation and occas ional frame lost due to the missile phase motion of television guided bombs , a modified weightˉrelated function, t arget tracking strategy, template updating and modifiˉ cation, and tracking point positioning method as well as a predict ion method to solve the frame loss of target were proˉ posed.
