摘　　要：介绍了圆形冷屏限制下投影面积的一种准确计算方法。该方法完全基于解析几何中的相关公式在MATLAB中做代数计算,由于其中没有引入任何近似处理,因此没有分析误差。此外它还具有编程简单,使用方便等特点。An accurate method for the computation of area of projected surface under limitation of circular cold shield is presented. It is totally based on the algebraic operations with related formulae of analytical geometry and realized in MATLAB. Because no approximated treatment is introdueed during the process, no analytical errors are existed. It also has the advantages such as simple in programming and convenient in using.
