The difference of cartilage between rat, rabbit and human was in the third stratum and the tidalline.
兔软骨的第三层是典型的柱状细胞层，潮线明显；

Results: Chondrocytes of rats in high dose group were hyperplastic, bulky and cells plasma was rich. Tidalline disappeared and the extent of bone trabeculae increased significantly.
结果大剂量组大鼠软骨细胞明显增生，体积大，胞浆丰富，潮线消失，骨小梁明显增宽。

A method is presented, by which the plane strain state on the earth's surface can be obtained with the combination of tidalline strain data and the tidal shear strain can be simulated numerically.
