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。

Early in pre-production Geonosis was known simply as the "rock planet," a rugged world of red soil and stone, reminiscent of Mars and the desolate buttes and mesas of the American southwest.

制作初期的吉诺西斯只简单地被形容为一个&岩石星球&，有著红色的土壤及岩石，令人联想到火星，荒芜的山丘以及美国西南部的台地地形。

Up in the mountains are clear lakes, quick-moving small rivers, and huge formations of rock. One huge rock is called Half Dome. It rises more than two thousand seven hundred meters into the air.

在山中，有清蓝的湖泊、有快速流动的小河流，还有巨大的岩石群，其中一个最大的岩石叫半圆丘，它高达2700米，直插云宵。

You can also use the rock and cord technique where you place a 1.5 rock under the two tarp layer and then squize the tapes into a narrow neck around the rock and tie this tight with a cord.

您也可以使用岩石和脊髓技术，您一个1.5 岩下的两个篷布层，然后squize到磁带一个狭窄的颈部周围的岩石和领带这个紧凑的脊髓。

When I saw this rock, Castle Rock, I said to myself that I wanted to frame it with a tree. I looked and looked and looked but could not find any tree with good form to accentuate the rock in my picture.

当我看到这个名为Castle Rock的岩石，我告诉自己想要有一棵树的构图来拍它，我找了找，但就是无法找到一个很好的形状来强调我照片中的岩石。

The parameters of anisotropy of isothermal remanent magnetism are directly related to the shape of magnetic carrier minerals in rocks. They reflect the deformation and dislocation of carriers under compaction.

与非滞后剩磁各向异性的参数一样，等温剩磁各向异性的参数直接与岩石中的携磁矿物颗粒形状有关，它直接反映了岩石形成与压实作用下携磁矿物的变形和变位。

Unlike igneous rocks which are formed from molten rock material, sedimentary rocks are made up of particles of previously existing rocks, including igneous, metamorphic and sedimentary rocks.

沉积岩不像火成那样是由熔融的岩石物质形成，沉积岩是由早先存在的浆岩，变质岩和沉积岩的矿物碎屑及岩石屑组成的

Todd entura of the Uniersity of Illinois-Chicago will describe what may be the earliest archaean fossil eidence yet discoered-rock samples that are 2.71 billion to 2.65 billion years old that were collected from a deep underground gold mine in Ontario, Canada.

Todd entura将描述迄今为止发现的最早的古化石证据――在加拿大安大略省某地下深层金矿中发现的距今约27亿1千万年到26亿5千万年岩石标本。entura于他的同事发现该岩石中含有一种类脂，或者说是一种含油化合物，这种类脂只存在于古细菌细胞膜中。

Meters liquid presses drill machine is mainly used to drill to explore various depth as 200 meters any kind of angle of bore . It can drill a hole in the rock of different degrees of hardness. Drilling a hole in the coal seam, soft rock and in the farmland beat the well time and limited efficacy rate .

200米液压钻机主要用于钻探各种深度为200米左右的各种角度的各类用途的孔，可在不同硬度的岩石中钻孔，而在煤层、软岩石中钻孔以及在农田打井时效率最高。

Although I'm just a guest editor, I still aspire to be the only "three nevers" editor in the history of So Rock: one who has never bought So Rock, never delved into rock music, and who has never associated with musicians.

虽然我只是一个客人的编辑，我仍然渴望成为唯一的&三玩&编辑器上的岩石：所以从未买这么岩石，从不对摇滚乐，并没有伴随的音乐家。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
