请问有人知道衡量粉体流动性的卡尔指数（carr
不好意思啊,找到英文的,不会翻译吖.
The Carr index is an indication of the compressibility of a powder.It is calculated by the formula C=100\frac{V_B-V_T}{V_B},where VB is the freely settled volume of a given mass of powder,and VT is the tapped density of the same mass of powder.It can also be expressed as C=100\times(1-\frac{\rho_B}{\rho_T}),where ρB is the freely settled bulk density of the powder,and ρT is the tapped density of the powder.
The Carr index is frequently used in pharmaceutics as an indication of the flowability of a powder.A Carr index greater than 25% is considered to be an indication of poor flowability,and below 15%,of good flowability.[1]
The Carr index is related to the Hausner ratio,another indication of flowability,by the formula C=100\times(H-1).
