对13种二元固溶体中的Manning空位风扩散系数进行了系统的分析，从文献中获得的示踪剂扩散系数实验数据是可靠和全面的。报道了一些简单而有趣的观测结果，包括钻石立方Ge-Si二元固溶体的 ~ 值为1.85.建议在CALPHAD扩散系数(流动性)评估中不包括空缺风系数，因为其影响基本上已包括在拟合参数中。对于那些直接使用扩散系数(不是迁移率参数)的人，对于fcc和bcc固溶体来说，这个因素仍然可以忽略，因为最大的影响只是互扩散(化学扩散)系数分别增加了28%和38%。对于低温下金刚石立方相的低扩散系数体系，特别是示踪剂扩散系数相差数量级的体系，可以考虑这一因素。
A systematic analysis was performed on Manning’s vacancy wind factor for diffusion in 13 binary solid solutions for which experimentally measured tracer diffusion coefficient data collected from the literature are reliable and comprehensive. Some straightforward yet interesting observations are reported, including a value of ~ 1.85 for the diamond cubic Ge-Si binary solid solution. It is recommended that the vacancy wind factor not be included in the CALPHAD diffusion coefficient (mobility) assessments since the effects have essentially been included in the fitting parameters. For those who use diffusion coefficients directly (not mobility parameters), the factor may still be ignored for both fcc and bcc solid solutions since the maximum effect is only a 28% and 38% increase in the interdiffusion (chemical diffusion) coefficients, respectively. The factor may be included for low diffusion coefficient systems of diamond cubic phases at low temperatures and especially for those systems whose tracer diffusion coefficients differ by orders of magnitude.
