0　引言在生产电线的过程中,一般需要在电线外部包裹一层不导电的聚合物。为了保证电线和绝缘层的质量,在包裹过程中控制连接电线的温度是至关重要的。在电线的生产过程中一般有两种温度的测量方法:直接接触式测量和无接触式测量。直接接触测量将会严重影响电线的质量。尽管无 0 Introduction In the production of wire, it is generally necessary to wrap a layer of non-conductive polymer outside the wire. In order to guarantee the quality of wires and insulation, it is of crucial importance to control the temperature of the connecting wires during the wrapping process. There are two general methods of measuring temperature in wire production: direct contact measurement and contactless measurement. Direct contact measurement will seriously affect the quality of the wire. Though nothing
