On the other hand, if duration of IVM is too long, it would lead to oocyte degradation and the phenomenon such us low cleavage rate and so on.
而培养时间过长则可能导致卵母细胞退化，同样也会引起卵裂率较低等现象。
There was no significant difference in fertility rate, cleavage rate, high-quality embryonic rate and graftage embryonic number between these groups(P>0.05).
各组间受精率、卵裂率、优质胚胎率、移植胚胎数比较差异均无显著性（P>0.05）。
The results indicated that there were no notable difference between granulosa cell monolayers group and cumulus cell monolayers group for the cleavage, blastocyst and hatched rate (P>0.05).
结果表明，就卵裂率、囊胚率和囊胚孵出率而言，壁颗粒细胞单层组与丘颗粒细胞单层组之间无显著差异（P>0.05）；
Objective: To determine the rate constants for the cleavage of pyrophosphate to phosphate by human serum apo-transferrin.
目的：测定人血清脱金属铁传递蛋白裂解焦磷酸键的反应速率常数。
Temperature could influence not only the dechlorination rate, but also influence the reaction pathway. Dechlorination was first and then the cleavage of benzene ring at higher temperature;
温度不仅影响脱氯速率，而且影响氯酚去除的途径，温度较高时，氯酚先脱氯后开环；
