Tritium has the ability to permeate elastomers and metal walls, particularly when the walls are heated. It is for this reason that tritium systems are usually put inside secondary enclosures or glove boxes. Since it is likely that the glove box atmosphere will eventually become contaminated with tritium, an atmosphere clean-up system is often required. This clean up system is sometimes referred to as a Secondary Enclosure Clean-up System or SEC System. The clean-up system can also regulate temperature, humidity, and remove other impurities.\u6c1a\u5177\u6709\u6e17\u900f\u5f39\u6027\u4f53\u548c\u91d1\u5c5e\u58c1\u7684\u80fd\u529b\uff0c\u5c24\u5176\u662f\u5f53\u58c1\u88ab\u52a0\u70ed\u65f6\u3002\u6b63\u662f\u7531\u4e8e\u8fd9\u4e2a\u539f\u56e0\uff0c\u6c1a\u7cfb\u7edf\u901a\u5e38\u88ab\u653e\u7f6e\u5728\u4e8c\u6b21\u5916\u58f3\u6216\u624b\u5957\u7bb1\u5185\u3002\u7531\u4e8e\u624b\u5957\u7bb1\u7684\u5927\u6c14\u53ef\u80fd\u6700\u7ec8\u4f1a\u88ab\u6c1a\u6c61\u67d3\uff0c\u6240\u4ee5\u901a\u5e38\u9700\u8981\u4e00\u4e2a\u7a7a\u6c14\u51c0\u5316\u7cfb\u7edf\u3002\u8fd9\u79cd\u6e05\u7406\u7cfb\u7edf\u6709\u65f6\u88ab\u79f0\u4e3a\u4e8c\u7ea7\u5c01\u95ed\u6e05\u7406\u7cfb\u7edf\u6216SEC\u7cfb\u7edf\u3002\u6e05\u6d01\u7cfb\u7edf\u8fd8\u53ef\u4ee5\u8c03\u8282\u6e29\u5ea6\u3001\u6e7f\u5ea6\u548c\u6e05\u9664\u5176\u4ed6\u6742\u8d28.<\/p>\n
