介绍了一种改进的“透镜”算法。用该算法和相应的实验研究了两种自发射阳极的静电场特性（尖锥直径为１０~１ｎｍ），其电场放大系数达到１０~２。并研究了在阴极尖锥附近的电场强度与尖锥结构的关系：分析了表面粗糙程度的影响。最后所得的计算机算法和程序适用于研究任意形状的纳米尖锥阴极。
An improved “lens” algorithm is introduced. Using this algorithm and the corresponding experiments, the electrostatic field characteristics of two kinds of self-emitting anodes (cone diameter of 10 ~ 1nm) were studied, and the electric field amplification factor reached 10 ~ 2. The relationship between the electric field strength and the cone structure near the cathode tip was also studied. The influence of surface roughness was analyzed. The resulting computer algorithm and program are suitable for investigating nanoscale pyramidal cathodes of arbitrary shape.
