阿列尼乌斯模型在红外微型金属杜瓦的真空寿命试验研究中的应用

The Application Of Arrhenius Model In The Experimental Study On The Vacuum Life Of Infrared Miniature Metal Dewar

红外微型金属杜瓦是红外探测器中必不可少的一种电真空组件。本篇介绍了它的结构特点,并探讨运用阿列尼乌斯模型进行加速寿命试验的方法,来估计红外微型金属杜瓦常温状态下的真空寿命。

The miniature metal Dewar is an electric vacuum modle which is absolutely needed for the infrared detectors. The vacuum life of the metal Dewar is very important for the I R systems to have good performance. The structure feature of the Dewar was briefly described in the paper. The Arrhenius model was discussed in detail to update the accelerated life experiment of the Dewar to evaluate its vacuum life in normal temperature.
