摘要： 从理论上建立了可压缩体的滑移线场理论，并给出了解析实例。研究表明，在平面应变条件下，可压缩体内的两族滑移线不仅不正交，而且随着平均正应力的不同而变化；可压缩体的平面应变问题可以直接采用现有的致密体的滑移线场来求出。

Abstract: The slip line equation for compressible materials is established theoretically, and analytical examples are given. The resultes show that two group slip lines of compressible materials under plane strain condition are not normal each other and the angles change with average normal stress. Based on the slip line field for full dense materials, the problems of the plane strain for compressible materials can be solved.

Key words: Compressible material, Mohr sires Circle, Slip line field theory, Power Coefficient, Power Fluctuation, Power Loss, Tower Shadow, Wind Shear, Wind Turbine
