Derives the formulae for calculating the distortion and stress on the acting surface of flexspline load in the drive process of the harmonic gear drive with three-wave wavegenerator;(2) analyzes and compares the performance of plastic and steel products under light load drive and calculates the probably reached limit of drive ratio for both types of flexsplines under the same load;(3) applies the harmonic gear drive with three-wave wavegenerator to the small-sized multiple-revolution electric device of valves by taking into consideration of the low limit of the drive ratio for the harmonic gear drive with three-wave wavegenerator made of plastics, improves the design on the main drive mechanism of the traditional small-sized multiple-revolution electric device of valves, and validates through examples the feasibility for the harmonic gear drive with three-wave wavegenerator made of plastics to be applied to the small-sized multiple-revolution electric device of valves. Finally the author performs calculations on the two types of the flexsplines of the harmonic gear with three-wave wavegenerator by using the finite element method and analyzes the causes for the errors.

World War II expansion programs led to construction of two large groups of subchasers, the new 110-foot wooden-hulled craft and the 173-foot steel-hulled type. By 1943, it was felt desirable to differentiate between the two types. The type symbol PC was retained for the steel 173-footers, and the separate symbol SC was adopted for the 110-foot vessels.

根据二战舰队扩充计划开始建造两个型号的猎潜艇，新110尺木制艇和173尺钢制艇。1943年海军觉得应该对两型艇加以区分。173尺钢制艇保留PC编号系统，而单独的SC编号系统被分配给新110尺木制艇。
