热循环稳定性 meaning in Chinese

thermal cycling stability

Through the research of crosslinking of matrix resin , heating treatment of composite and mixing of different polymer , we draw some conclusions : 1 、 percolation theory can explain the phenomenon of the jump of resistance when the content of cb reach a critical volume ; 2 、 based on ohm conduct theory , abounded to the percolation the wbibull statistical theory and other theory , an adapted theory was obtained to explain the jump of resistance and the other phenomenon ; 3 、 the ntc phenomenon was eliminated by crosslinking the matrix of conductive composite , at the same time the stability of composite was improved
通过对基体树脂的交联、复合材料的热处理、聚合物共混物的研究得出了如下的结论： 1 、渗滤理论能够很好的解释导电粒子含量达到某一值时电导率剧增的问题； 2 、在欧姆导电模型的基础上，综合应用了weibull统计理论模型，结合原来的体积膨胀等理论，成功的解释了ptc复合材料在基体材料熔点附近的跳变问题、 ntc现象以及热循环稳定性等问题； 3 、有机ptc导电复合材料经硅烷交联以后能够消除ntc现象，改善了导电复合材料的稳定性能。
