中文摘要：

表征药用粉体的流动性的方法主要有：休止角法、HR法、Cart流动性指数法、Jenike流动函数法、分形维数法及质量流率法等。以流动性有差异的药用粉体为研究对象，对物料进行综合特征的测试与表征。测试结果采用多元分析方法评价，并与质量流率法进行比较，发现使用多元分析方法对粉体的流动性评价是可行的。根据实际生产情况实现对药用粉体流动性的排序可以得到明确量化的临界值，改变了过去依赖休止角、压缩度等单参数表征粉体的流动性方法，对于粉体流动性评价形成了相对客观的标准。

英文摘要：

The main methods of characterizing the flowability of pharmaceutical powders include repose angle method, HR method, Carr＇s index method, Jenike flow function method, fractal dimension method, and mass flow rate method, etc. Regarding powders with different flowabilities as the research subject, comprehensive features of pharmaceutical materials were investigated and characterized. The multivariate analysis method was employed to evaluate and analyze flowability values of the tested pharmaceutical materials. Comparing with the method of the mass flow rate, it was feasible to use multivariate analysis method to evaluate the flowability of powders. Simultaneously, the flowability of pharmaceutical materials could be ranked and definitely quantified, and critical values be determined according to the actual production, which has promoted the previous methods dependent only on the single parameter, i.e. repose angle and compression degree methods. A relatively objective standard method of evaluating flowability of powders is formed.
