CCSD怎么记

Characteristics and effect factors of seismic velocity in metamorphic rock area: An example from CCSD borehole area

变质岩区地震波速度的特点及其影响因素&以中国大陆科学钻探孔区为例

So it is very realistic to make a systemic study on the management mode of CCSD and conclude its project management experiences.

因此，对CCSD的项目组织管理模式进行系统的研究，以期总结CCSD所获得的项目组织管理经验和完善其项目管理，具有十分重要的现实意义。

A fission track dating was carried out on 11 apatite samples from the 1028. 68 in-deep pilot PP2 of the Chinese Continental Scientific Drilling ( CCSD). The fission track ages are 52. 0~ 79. 6 Ma.

对中国大陆科学钻探预先导孔（CCSD-PP2）的11个钻孔岩心样进行了裂变径迹年龄测定，其中10个样品的结果为79.6～52.0Ma。
