The results shows that the REE of Shuixigou Group came mostly from andesite and granite in the denudation zone,but did not originate from basalt.The pH values of the interlayer oxidation rock zone and the primary reduction rock zone are similar,and those of ore zone are lower than the other two zones.

伊犁盆地南缘乌库尔其地区流体和岩石的 pH值分布情况表明，层间氧化岩石带和原生还原岩石带的 pH值相似，而矿石带的 pH值偏低，这与在偏碱性条件下， REE和 U的络合物容易形成，并且 REE和 U的络合物随着 pH值的降低而迁移和沉淀富集是相吻合的。

Working from outside the basin in to the Mare Basalts, they find the surface composition changes from Feldspathic breccias (Feldspar is a rock that crystallizes from magma) to shocked Anorthosite (a type of feldspar that makes up the light areas of the moon), to unshocked crystalline anorthosite, to high Calcium pyroxene (a rock made of silicate minerals) and pyroclastic rocks in the center.

研究发现：从盆地外边到盆地内部的玄武岩海（盆地内部的熔岩形成的地质结构），月球表面的地质结构依次是：长石质的角砾岩（长石是火山熔岩结晶形成的岩石）、经过冲击的粒状火成岩（构成月球阳面的一种长石）、没有经过冲击的粒状火成岩结晶体、高钙辉石（一种由硅酸盐构成的岩石），最中心的位置是分裂状的火山岩石。

The major results about magnetic petrology of high-grade terrenes of Archean shield areas in the world are reviewed in this article,focusing on the relationship between rock magnetism and deformation, and metamorphism and intensity of magnetization of continental lower crust and its origin.

综述国际上有关太古宙高级地体磁性岩石学研究的主要成果，侧重高级地体岩石磁性与变形、变质等级的相互关系及大陆下地壳磁化强度及其成因机制等；提出了有关高级地体岩石磁性研究中值得注意的几个问题。

Correlation of drillability anisotropy index of the roller cone bit and PDC bit, the difference between drillability of the roller cone bit in perpendicular and horizontal directions of the bedding plane with the P-wave velocity anisotropy coefficient are studied respectively by means of mathematical statistics. A mathematical model is established for predicting drillability anisotropy index by using P-wave velocity anisotropy coefficient.

用数理统计方法研究分析了牙轮钻头岩石可钻性各向异性指数、牙轮钻头垂直于和平行于地层层面方向岩石可钻性差值和PDC钻头岩石可钻性各向异性指数与纵波波速各向异性系数的相关关系，建立了用纵波波速各向异性系数评价地层可钻性各向异性的模型。

The variation of the mechanical properties, including peak stress, Young's modulus and poisson ratio of Gypsum Breccia, was obvious. The peak stress and Young's modulus were improved after drying. The mechanical properties were obviously affected by the natural water content.

烘干后，岩石的力学性质发生了很大的变化，峰值强度、弹性模量都有很大的提高，岩石表现出脆性，岩石的天然含水率对烘干后的力学性质改变影响很大。

The geologist needs to know what rocks the drill has reached, so every so often a sample is obtained with a coring bit. It cuts a clean cylinder of rock, from which can be seen the strata the drill has been cutting through.

地质学者需要了解钻探到了什么岩石，所以经常会从钻头穿过的岩层中得到一些岩石样本，切割岩石成为圆柱体。

The variation regularity of joint size and the shear strength of fractal rock joints with different fractal dimensions were subsequently studied by using the numerical direct shear test method.

为了研究岩石节理抗剪强度参数取值中的尺寸效应问题，采用随机分形方法，重构了岩石节理剖面线，在此基础上，应用数值直剪试验方法，研究了不同分维值岩石分形节理抗剪强度参数随节理尺寸的变化规律。

Owing to inborn high temperature and high pressure gas after blasting and complexity of dynamic principal relationship and interact ional complexity between dynamite and rock and non-equal character and anisotropies of rock, the rock blasting mechanism research is quite complex.

该过程由于炸药爆炸后生成的高温、高压气体产物和岩石动态本构关系的复杂性，炸药与岩石之间相互作用的复杂性，以及岩石本身的非均质性和各向异性等使得岩石爆破机理的研究显得十分复杂和困难。
