Thus, the serummedium can't be used as ESCs medium without feeder.
因此，在没有饲养层的条件下，表皮干细胞的培养必须添加条件培养基。

The wear volume of bone cement samples in the calf serummedium is larger than that in the air and increases with the contact load increase.
骨水泥试样的磨损量在小牛血清介质中比在空气中大，并且随接触载荷增大而增大。

In calf serummedium, the wear mechanism of fretting is mainly adhesive wear, fatigue wear and the weakening effect of solution molecules on the bone cement matrix under stress.
