为评定片剂的机械性质,建议用撞击,压缩或磨擦等各种方法来检验片剂的坚固性(在某些情况下也测定硬度)。最普遍采用的是试验片剂的抗压强度,同时大多数的仪器将片剂侧面放置。假设物料在破裂之前只受到压缩的力。但是,不同大小的片剂其直径与高度之比在很大的范围内变动, In order to assess the mechanical properties of tablets, it is advisable to check the firmness of the tablets (in some cases, the hardness is also measured) by various means such as impact, compression or abrasion. The most commonly used is the compressive strength of the test tablet, while most instruments place the tablet sideways. It is assumed that the material is compressed only before rupture. However, the ratio of diameter to height of tablets of different sizes varies over a wide range,
