对真空冷阱中处于滑流区的气体换热，应考虑温度跳跃和速度滑移对换热的影响。
The effects of the temperature jump and the velocity slip on the heat transfer for the slip-flow regime in the cold trap of the freeze dryer are considered.
可显示样品温度曲线、隔板温度曲线、冷阱温度曲线、真空度曲线。
Sample temperature curve can be displayed, a separator temperature curve, thetemperature curve of the cold trap, vacuum curve.
那末务求不宽大，能够取舍有油泵，加上一些防油净化措施，如加冷阱、障板、挡油阱等，也能达成肮脏真空务求。
Then the view is not large, to choose a pump, plus some oil purification measures, such as the Canadian cold trap, baffle, retaining the oil wells, but also in order to reach a dirty vacuum.
