| 摘 要： | 介绍了一种处理HL-2A汤姆逊散射原始实验数据的新方法——最大似然法。该方法用数理统计的手段，通过使理论推导出的数据与实际采集到的散射数据最大可能的一致，得到了较准确的等离子体电子温度Te和密度ne。将计算所得的结果与现在汤姆逊散射系统所用的比值法得到的结果相比较，验证了该方法的可适用性，并能够克服比值法的一些缺陷。

| Abstract: | Maximum likelihood method to process the data of HL-2A Thomson scattering system is presented.Using mathematical statistics,this method maximizes the possibility of the likeness between the theoretical data and the observed data,so that we could get more accurate result.It has been proved to be applicable in comparison with that of the ratios method,and some of the drawbacks in ratios method do not exist in this new one. |
