    文中，首先通過建立系統的數學模型，分析了逆變電源並聯運行的工作原理以及並聯系統的一些主要特性，包括它的環流特性、功率特性和電壓閉環調節特性；在此基礎上，又研究了幾種典型的並聯運行控制方式；然後，採用搶占與並發相結合的同步控制方式和反饋與下垂特性相結合的負載均分控制設計了並聯控制器。
  2. Abstract : it is observed that the sommerfeld ' s formula for a progressive spherical wave is not covariant with respectro the rotation of the coordinate system. it contains complex partial waves that are not physical. the standing wave representation of the same formula is shown to be covariant and physical. it is applied to solve the boundary value problem of fiber optics. the radiation modes as well as the guided normal modes are obtained in closed forms. the intensity distribution in various modes is obtained. it is remarked that the mode of critical refraction is missing

    文摘:說明了球面行波的索末菲公式在坐標轉動下不協變.證明了球面波的駐波表示是協變的，因而是一個物理的關系式，故適用於圓柱坐標中各類波動方程的定解問題.作為一個例，應用於光纖光學，導出了受導簡正模和輻射模的表達式，以及各模式的強度分佈
