1985年7月25日至7月30日在成都召开了低温容器的活动抽气咀的性能鉴定会。这类活动抽气咀是由兰州物理研究所研制成功的。成都液氮容器厂对活动抽气咀进行了较长时间的性能实验。与会代表认为这项工艺设计正确、性能稳定、实验数据完整,有较大的推广价值。活动抽气咀的研制成功对液氮生物容器的制造水平的提高创造了条件. July 25, 1985 to July 30 held in Chengdu, the activities of cryogenic container suction Tsui performance appraisal meeting. Suction Tsui such activities are developed by the Institute of Physics Lanzhou. Chengdu liquid nitrogen container plant on the activities of pumping nozzle for a longer time performance test. Participants believe that the process design is correct, stable performance, experimental data integrity, a greater promotional value. The successful development of the active suction nozzle has created conditions for the improvement of the manufacturing level of liquid nitrogen biological containers.
