摘　　要：本文将非正交曲线坐标系下的有限差分算法和四阶龙格-库塔法结合起来研究了微尖场致发射三极管的静电特性．计算模型中的阴极为塔形（Tower）结构．本文给出了尖端场强与几何结构的关系曲线、电子轨迹图以及阳极电流密度分布．The emission characteristics of point-type field emitters are discussed numerically by using a combination of Finite-Difference Method in Non-Orthogonal CurvilinearCoordinate System (FDM-NOCCS) and Fouth-order Runge-Kutta method. Results arepresented for the triode model with 'Tower' structure emitter. The dependence of theelectric field intensity at top on geometry structure, the sketch of the electron trajectoriesand the current density distribution at the anode are shown.
