论述了积分球法和集总参数法测定激光吸收率的原理。采用这两种方法测定了双相钢在激光热处理过程中对YAG激光的吸收率。试验结果表明，积分球法和集总参数法测得的激光吸收率数值非常接近，双相钢的激光吸收率与温度相关。
論述瞭積分毬法和集總參數法測定激光吸收率的原理。採用這兩種方法測定瞭雙相鋼在激光熱處理過程中對YAG激光的吸收率。試驗結果錶明，積分毬法和集總參數法測得的激光吸收率數值非常接近，雙相鋼的激光吸收率與溫度相關。

The principle of laser absorptivity measured by the integrating sphere method and lumped parameter method was discussed.The YAG laser absorptivity of dual-phase steel during laser heat treatment was measured by these methods.The test results show,the laser absorptivity values measured by the integrating sphere method and lumped parameter method are very close,and the laser absorptivity of the dual-phasesteel is temperature-related.
