摘要

<正>In higher vacuum field, one of the main factors of affecting the degree of vacuum is the pollution of vacuum pump oil,which is mainly caused by the back-streaming of the backing pump oil. Based on the technology of semiconductor refrigeration, the semiconductor cold trap is designed. The trap can be effectively used to resist the back-streaming of oil,thereby to increase the degree of vacuum. The basic principle of a semiconductor refrigeration apparatus is:to connect it with power supply, the
