采用有限元方法，计算分析了电站200MW汽轮机中压主汽阀阀壳在冷启、停机、强热启动、极热启动以及事故等工况下的温度场和应力场，得出了阀壳裂纹区各工况下温度场和应力场的变化规律，提出了内壁裂纹区的周向应力是疲劳寿命计算的主要参考量。

According to the special requirements for centrifugal pump PIV measurement, a PIV testing platform was established to measure the instantaneous velocity in the double-channel pump with different impeller design, i.e., the double-channel impeller and the two-blade impeller, under different working conditions. The measured absolute velocity fields were transfered to relative velocity fields by specially developed code.
