When the temperature is below 0℃, in nascent period of cyclone, it is showed there are fine water vapor conditions anywhere in cyclone. In developing period of cyclone, there are fine water vapor conditions at the fore of cold and warm fronts. After cyclone occlude, there are only fine water vapor conditions at fore warm front and cyclone center.

The total static loads and dynamic loads are summed as 4.692W and 38.4W, respectively. And comparison between the double-wall cooling method and the cooling tube method for the 77 heat shield has been discussed to provide the thermal parameters for flow process simulation. The critical thermal parameters of the main components of the QWR cooling system were determined for parallel arranged QWR cryostats. The mass flow and time for cool-down of the QWR to 4.2K was also estimated.
