通过模拟均匀热浴气体中的分子扩散和平行平板间的通道流动，研究了具有帕克转动能增益函数的连续转动能统计非弹性截面（SICS）模型的输运系数。研究表明，SICS模型的输运系数与Chapman-Enskog（CE）理论、Euken修正（EC）和推荐的数据不一致，这是由于模型高估了有效碰撞频率。通过引入约化碰撞参数，修正了SICS模型的散射定律。修正的SICS（MSICS）模型的传输系数与CE，EC解决方案，并推荐的数据，除了低温范围内的合理协议。
Transport coefficients of the Statistical Inelastic Cross-Section (SICS) model for continuous rotational energy with Parker's rotational energy gain function are examined by simulation of molecular diffusion in a homogeneous heat bath gas and channel flow between parallel flat plates. This study reveals that the transport coefficients of SICS model are inconsistest with the Chapman-Enskog (CE) theory, Euken correction (EC), and recommended data because of overestimation of effective collision frequency. The scattering law of the SICS model is modified by introducing the reduced impact parameter. Transport coefficients of the modified SICS (MSICS) model are in reasonable agreement with those of CE, EC solutions, and recommended data, except for the low-temperature range.
