The influences of the PTCR's characteristic parameters such as switching temperature, roomresistance of samples, and dissipation coefficient, etc. on the thermal power of heaters are investigated.
主要研究了PT C材料的开关温度、样品的室温电阻及耗散系数等特性参数对发热体功率的影响。

People began to dream of materials that had zero resistance even at roomtemperature.
于是人们开始梦想着发现甚至在室温下也能够具有零电阻的材料。
