the daily evaporation rate under different ambient temperature was measured and the change of evaporation rate during per measuring period was also obtained.
通过改变环境温度,分别测量得到对应的蒸发流量;并对常规测量环境下蒸气流量的变化规律进行了测试与分析。
daily evaporation rate is an important technology parameter to evaluate the heat-insulating property of cryogenic dewar.
率是评价高真空多层绝热杜瓦保冷性能最重要的技术参数。
the product is made of antirust aluminum alloy and structured with high-vacuumed super adiabatic multi-layers. it is ligh by weight and the daily evaporation rate of liquid nitrogen is very low.
该系列产品由防锈铝合金制造,高真空多层超级绝热结构,重量轻、液氮静态日蒸损量小。
