摘　　要：电离能下降的现象与等离子体的成分、电离分布、热力学、输运性质息息相关,其精确测量值对于整个实验的模型检验和方案设计都至关重要.本文考虑粒子数的涨落,对经典的Stewart和Pyatt的模型进行修正,并耦合进先前发展的等离子体模型.利用修正的模型对熊刚等人的实验进行了解释,发现当前模型所得结果要优于其他理论结果,与实验更加一致.The phenomenon of ionization potential depression is closely related to the composition,ionization distribution,thermodynamics and transport properties of the plasma.The value of ionization potential depression is crucial for the experimental model test and scheme design.Based on the previous plasma model developed by us,we considered the fluctuation and revised the model of Stewart and Pyatt.With new revised model,we give a brief description of the experimental results from Xiong et al.The present results are better than other theoretical results and are in good agreement with experimental results.
