摘要:

用高密度等离子体模型可以计算出一整套输运参数,并且在很宽的等离子体温度和密度范围内有合理的精度, 可广泛应用于Z箍缩等离子体、激光聚变和磁约束聚变等领域, 并将这个模型计算出的各种输运参数拟合成了实用的公式。

Abstract:

A complete set of transport coefficients with reasonable accuracy in a wide range of plasma temperatures and densities. Therefore , they are useful for numerical simulation in magnetic confinement fusion , laser fusion , and Z  pinch plasma , etc. The analytic fitting of transport coefficients in a variety of conditions are given in this paper. The formulas can facilitate the calculation of transport coefficients for various applications.

Key words: Plasma , Transport coefficient , Chemical potential
