时效

According to various of the technical difficulties such as low drilling efficiency in hard rock and short service life of diamond drilling bit, analysis was made on the inherent links between blade-extruding of hot-pressing diamond and rock abrasiveness.

中文摘要：针对在坚硬致密岩石中钻进时效低和钻头使用寿命短的技术难题，分析了热压钻头的金刚石出刃与岩石研磨性等岩性之间的内在联系，认为钻头的胎体成分及其性能是关键，硬而带脆性的胎体性能有利于金刚石出刃，从而能提高钻进速度。

In order to solve the problem of low efficiency and short service life of hot pressed diamond bit when drilling in hard and compact formation, relations between diamond exposure of hot pressed bit and rock abrasiveness were analyzed in this paper. Research on matrix performances of hot-pressed diamond bit was firstly carried out.

针对在硬而致密岩石中钻进时效低的难题，本文分析了碳化钨基热压钻头的金刚石出刃与岩石研磨性等岩性之间的内在联系，认为钻头的胎体成分及其性能是关键，硬而带脆性的胎体性能有利于全刚石出刃，从而能提高钻进速度。

However, the rationality of the notion cannot be neglected. Its rationality lies in the fact that truth is concrete, and is a process, and has the effectiveness for a given period of time. Pragmatism notion of truth defies the rigid truth notion of abstractionism and dogmatism, and it advocates a difference between the sheer subjective feeling and the objective existence. As a result, it expands the conten...
