Preliminary investigation on high performance cryogenic heat transfer based upon natural circulation cooling 基于自然循环预冷过程高效低温传热方法的初步研究
It mainly explains why it causes the damage of equipment in some occasions ( e . g . , the circulation cooling water system of open pattern ) 在某些场合（如敞开式循环冷却水系统中） ，它成了设备损坏的主要原因。
This method not only wastes cryogenic fuel , but also causes safety problem . it is necessary to develop new type of precooling method , so the natural circulation cooling system is introduced 因此，为节约推进剂，提高发射的可靠性，简化地面系统以及发射前的操作程序等，需要立即开展新型的自然循环预冷法的研究。
