摘要：
Several methods are presented to quantitatively measure the wear of compressed tablets. The natural logarithm of the weight fraction, W/W(O), decreases linearly with increasing wear time. Thus, the wearability of a tablet may be described by a first-order rate constant or its half life. As the wear process continues there may be more than a single rate constant depending on the geometry and structural homogeneity of the tablet.
