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。

剑，首先从战场格杀进入人们视野，后来随着骑兵作战对砍劈的需要逐渐从军事前台退出，被人们移作他用。第一，进入社会生活的剑，在王者对剑"天下"和"军权"的新解读中，作为权力的象征和控制的对象，剑成为王者的赏赐之物和权力的有限让渡。第二，进入社会生活的剑，原先兵剑制作对硬度和韧性的考究，在达观贵族的佩带中转化装点的热情、形成"带剑"阶层和年龄的界定，并从不同装点和规定中折射社会地位。第三，进入社会生活的剑，兵剑实践形成的锋之刺、刃之斩技术，在武术人手中深化为"三锋四刃"的认识，建构了不同方法的技术系统，形成了"工行醉棉"演练体式；在大众手中成为砍病魔、挥心理阴影的健康道具。

Methods 28 inpatients with all of 58 deep burn wound on the function part were selected in this study. After the eschar was removed with Goulian, the wound was covered with meshed skin, autologous split-thickness skin sheet.
