摘要：
The tensile and compressive strength of cylindrical compacts of lactose and microcrystalline cellulose has been assessed by diametral compression and axial loading, respectively. The ratio of the compressive to the tensile strength of the specimens indicates that lactose is more brittle in character than microcystalline cellulose. Thus, the test procedure provides a method of characterising the mechanical properties of the powders.
