m And so you lose your m, and so you see that y center of mass then becomes the square root of three divided by eight times l.
你失去了，得到了y轴质量中心,成了平方根,3除以8再乘l开方。
The results showed that MDA content was lower (P<0.05) in group Y than that in group P. However, MDA content showed no significant difference between group L and M (P>0.05).
试验结果表明：胰岛素可降低肝脏MDA含量（P<0.05），但酪蛋白酶解产物对MDA含量无显著影响（P>0.05）。
