bore expansion meaning in Chinese

炮膛膨胀

This paper studied two - dimension model of rotor and cylinder and builded the finite element model . generally take the rotor and the cylinder as control objects ， definite their boundary conditions ， solute their temperature fields ， and then analyst their bear expansions and distortions as well as thermal stress distribute ， to control the courses ， and keep the unit the most optimum operating condition . and put the theories into practice developed by c + + program , used as the important part of the online monitoring and management system of life of the steam turbine
本文对汽轮机转子和汽缸的二维模型的进行分析，建立有限元模型；将汽轮机转子和汽缸作为控制对象，确定其边界条件，求解其温度场，分析其热膨胀、热变形以及热应力分布；采用c + +语言编制汽轮机高压缸、中压缸以及缸体的温度场实时在线监测程序,作为汽轮机寿命在线监测与管理系统的核心部分，用以指导汽轮机的启停及运行过程，使机组可以安全的、经济的运行。
