The relations expressing the corresponding changes of the Factor A and Factor B in the binomial with the deviation factor and viscosity of natural gas are derived in the paper. 文章推导出二项式系数A、B随天然气偏差系数和粘度对应变化的关系式。
On the basis of non-Darcy percolation binomial and effective permeability of two-phase percolation, the concept of effective velocity factor of two-phase percolation is proposed and the mathematical model of gas-liquid percolation is established. 在非达西渗流二项式和两相渗流相渗透率(有效渗透率)概念的基础上,提出了两相渗流相速度系数(有效速度系数)的概念,建立了气液两相渗流数理模型(微分式);
The paper points out the defect in defining the load with the demand factor and binomial factor, puts forward the applicational conditions and the questions to be paid attention to, and gives a new formula. 指出供电设计中现有需用系数法和二项式系数法负荷计算方法存在的问题,提出了采用两种方法的应用条件和应注意问题,给出了一种新的补充算法。
