【摘要】　目的　优化牙釉质电子顺磁共振（EPR）谱拟合程序。　方法　将牙釉质EPR谱拟合程序中的RIS-BGS偏移量设置为定参，取优化值；增加手动拟合功能，可以将参数初始值直接代入高斯模型得到拟合谱。　结果　将牙釉质EPR谱拟合程序中RIS-BGS偏移量设置为定参后，其优化值为0.529，减少了变参数量；采用手动拟合功能有助于调整参数初始值；在自动拟合程序对于个别样品谱不能给出正确结果情况时，仍然可以通过手动拟合来得到一个近似的拟合结果。　结论　优化了EPR谱拟合程序的应用过程。
【Abstract】　Objective　 To optimize the enamel electron paramagnetic resonance (EPR) spectrum fitting procedure.　Methods　 RIS-BGS offset was set as a determined parameter in enamel EPR spectrum fitting program, and an optimized value was given for RIS-BGS offset. A manual fitting function was designed that can substite the initutial value into the Gaussian model function directly.　Results　 RIS-BGS offset was set as a determined parameter, the optimized value of which was 0.529. The number of parameters decreased; the manual fitting function maked it easier to select initial values for parameters. When the auto fitting program failed to give a correct result for some EPR spectrum, a fitting result could still be obtained with the manual fitting method.　Conclusion　 The application of the spectrum fitting procedure can be optimized.
