tube cooler

常见例句

Using single stage version PTC to reach the temperature below 30 K is a difficult task for high frequency pulse tube cooler.
采用单级高频脉冲管制冷机获得低于30 K的制冷温度是脉冲管应用的一个新方向。
A lowest no-load temperature of 13.8 K has been obtained for the first stage without thermal connector, which is a new record for the single-stage pulse tube cooler.
在没有热桥连接的情况下，单独测试第一级最低制冷温度达到13.8 K，这是单级脉管制冷机获得的最低制冷温度新纪录。
Use single stage version to reach the temperature of 20 K is a difficulty for high frequency pulse tube cooler(PTC). Multi-stage version is a popular method to reach the low temperature.
单级高频脉冲管制冷机直接降低到20 K以下温区存在很大困难，采用多级方案是高频脉冲管制冷机获得更低温度的主要方法。
