The bigger the animal is, the lower its surface-to-volume ratio; for every ounce of body mass, there is proportionately less surface through which heat can escape.
动物体型越大，其体表体积比越低；躯体每增加一盎司的重量，所能散发热量的表面就成比例减少。

The tensile shear properties, mass loss ratio and surface residual stress of the bond samples before and after the thermal cycling were measured. The tensile shear fracture morphologies were observed.
测试了热循环前后胶接试样的拉伸剪切性能、质损率和表面残余应力，观察了拉伸剪切断口形貌。

The utility model has larger void ratio and specific surface area and also increases the mass transfer efficiency between gas and liquid when used as packing in the packing tower.
