英文摘要：

Aiming at the research of general scroll profiles and its shape optimization, the coefficient parameter transformation characteristics of general arc functional scroll profiles based on instinct equation of tangent angle coefficient was studied. Through the analysis of specific characteristics of coefficient parameters, the speciality in each phase and commonness in whole phase of general arc functional scroll profiles was mastered. Through the shape optimization of scroll profiles, the compression ratio will be the biggest under the condition of assuring intention of root, which gave attention to excellency of both high intention and high compression ratio and make the best of compress efficiency. The research conclussions have a great theoretical and actual significance to the general scroll profiles and varying thickness scroll compressor.
