涡轮进出口氦氙工质设计的流速较低，氦氙工质入口段静温场与总温场差别较小，可以在一定程度上避免流动损失，易于涡轮工作。

The design flow rate of helium-xenon working fluid at the inlet and outlet of the turbine is low, and the difference between the static temperature field and the total temperature field at the inlet of the helium-xenon working fluid is small, which can avoid the flow loss to a certain extent and is easy for the turbine to work.
