Requests on resistance of corrosion destructibility of sealing interfaces that related to sealing up and cementing exercises in petroleum engineering are more and more of rigidity. It is urgently needs to resolve all sorts of problems that affect interface bonding quality. Conventional cement slurry design resist the destructive function worse, and can't like to satisfy the request to carry on latter production such as perforation, acidify, fracture etc.

常规油井水泥抵抗破坏的性能较差，不能很好满足水泥环抗冲击振动以及射孔、压裂等各种变形破坏的要求，这在一定程度上限制了小间隙、大位移、定向与水平井等特殊钻井工艺技术的发展，也制约了后期压裂、酸化等诸多开发工艺措施的实施。

Based on phylogenetic analysis, this paper reviewed the relationship between hormones including sex hormones and AVT, and vocal production and perception through all anuran species studied to date. We found that in anuran brains the AVT system related to vocal behaviors were very conservative while the sex hormone systems involved in vocal communication might be originated independently from varied taxa of anuran.
