围压对热敏电阻温度计性能以及对其温度场的影响

Effect of Confining Pressure on Thermistor-thermometerBehaviour and Temperature Fielt

在有一定高围压作用的动、静三轴冻土实验中，出现高压室内温度测量值不稳定以及突变现象，不是因为热敏电阻温度计本身受压后其特性变化所致，而是由于压力室内围压的变化（升高或降低）引起其温度场（油温）的变化所造成的．

in the dynamical or statical triaxialtests of frozen soils under a giver high confiningpressure, unstability or sudden change of observedtemperature occurs in the high presssure chamber.This phenomenon does not result from the changeo f thermistor itself under high prossure but fromthe change of temperature field in correspondencewith the confining pressure variation in the pressure chamber.
