The result shows that it is more reasonable, safe and reliable to adopt procedure with warm up before welding and post heat treatment after welding.
结果表明：采用焊前预热和焊后热处理的焊接工艺方案所获得的焊接接头比不采用以上措施获得的焊接接头更为合理，应用更安全、可靠。
The laser power density and the temperature of post heat processing have great effect on the sheet resistivity and TCR of PTC thermistor, and there exist optimum values for these parameters.
激光功率密度和后续热处理温度对PT C热敏电阻方阻和电阻温度系数影响较大，并都存在一个最佳值。
