saber中的一个器件，基于集总物理模型的晶闸管scr2，看help中结温改temp值，但是改了之后貌似结果和之前差别不大
help中的外部变量说明：
scr2 External Parameters
temp, include_stress
These are global parameters declared in header.sin. You can assign values to them for an instance of this template (such as in a netlist) without affecting their global values in the rest of your design. For example, the following allows you to change the simulation temperature to 58 for scr2.1 only:
scr2.1 a6 g3 0= model=(taub=15u, taug=3u), temp=58
想问各位，是不是还需要改其他参数呀
