为保证电工电子产品的可靠性,必须具备可以提供温、湿、压三个参数综合变化的试验设备.目前国内温、湿、压试验设备只能提供一个静态环境,无法保证温度、湿度、压力的变化速率和温湿度均匀性.研究此类三个参数的动态试验设备,乃是环境试验科学发展的需要.本文仅浅谈温度、压力的试验研究. In order to ensure the reliability of electrical and electronic products, it is necessary to have the test equipment that can provide comprehensive changes of three parameters of temperature, humidity and pressure.Now the domestic temperature, humidity and pressure test equipment can only provide a static environment, can not guarantee the temperature, humidity, pressure Of the rate of change and temperature and humidity uniformity.To study these three parameters of the dynamic test equipment, is the scientific development of environmental testing needs.This article only talk about the temperature and pressure of experimental research.
