  加装火箭推进器可使速度（也包括冲击动量）提高一倍，使炸弹钻入花岗岩的深度增加75 % ，钻入软土壤的深度更可增加到10倍之多。
• The artificial synthesis of hematite in granite can turn the color of common ligh - colored granite from grey or yellowish pink to red , which is of some significance in raising the utilization coefficient of common granite
  通过在花岗岩中人工合成赤铁矿，可使普通浅色（灰白、浅肉红色）花岗岩改变为红色，对提高普通花岗岩的利用率有一定意义。
• According to the constructive principles of these diagrams , the following aspects must be thought carefully : the rock types to be studied must be the same or nearly the same as those that can be discriminated by the diagram ; to avoid mixed or incorrect signals that could be produced , two or more such diagrams shall have to be jointly used ; for special rock types , such as a - type granites or potassic igneous rocks , special discriminative diagrams have to be determined and selected respectively ; the samples to be studied can not be altered ; in general , the diagrams must be used carefully with archean samples ; the petrotectonic assemblage or an expert system are recommended to be used together with the discrimination diagrams
  强调指出：所采集的样品必须新鲜（无蚀变或极弱蚀变） 、非堆晶的岩石；选择的判别图解必须与判别的岩石类型相一致，即对花岗岩类要用花岗岩的判别图解，不能用玄武岩的判别图解；对特殊类型岩石要选择专门用于该类型岩石的判别图解，如碱性花岗岩，钾质火成岩；要应用多种图解综合判断；不能用单个样品，而应作多个样品分析；要注意所选择判别图解的特别说明等。
• Based on the study on ree distribution characteristics of sinian low grade metamorphic rocks of the basement and cover volcanics , the author makes a discussion on the material source and the genesis of xiangshan volcanics , and suggests that xiangshan volcanics came mostly from the remelting of the upper crust , and the genesis should be attributed to the category of remelted granites
  摘要本文通过对相山火山盆地基底震旦系浅变质岩、盖层火山岩稀土元素分布特徵的研究，探讨相山火山岩的物质来源及岩石成因，认为相山火山岩主要是上部地壳重熔的产物，其岩石成因应属于重熔型花岗岩的?畴。
• The qiongzhong and danxian batholiths , as the largest early mesozoic syntectonic granite intrusions in hainan island , are mainly composed of porphyritic biotite two - feldspars granitoids , in which alkali - feldspar phenocrysts and dark minerals are foliated mostly in we - direction . the granites are of metaluminous i - type . major and trace elements show co - variations with sio2 , suggesting the fractional crystallization of plagioclase , hornblende , apatite and ti - fe oxides in the evolution of the granites
  花岗岩的主量元素和部分微量元素成分与sio _ 2呈良好的相关关系，显示出明显的斜长石、角闪石、磷灰石和ti - fe氧化物等的分离结晶作用，总体上它们与大陆岛弧花岗岩的微量元素丰度和分布特征相似，系统地亏损ba 、 nb 、 sr 、 p和ti等元素。
• The test results show that both the permeability of sandstone and that of granite with a single fracture decrease with increasing effective stress , following the law of exponential decay . the permeability sensitivity of granite to effective stress is more stronger than that of sandstone , but the permeability recovery capability of sandstone is more stronger than that of granite
  试验结果表明，在围压升降过程中，砂岩和单裂隙花岗岩的渗透率均随有效应西南交通大学博士研究生学位论文第日页力的增加呈负指数规律减小，但单裂隙试件的渗透率对有效应力的敏感程度远大于砂岩，而砂岩渗透率的恢复程度则远大于单裂隙试件。
• Based on the study of geologic characteristics , such as mineralogic assembladge , structural and textural features of granite of guidong granitic massif , and by using petrochemical , trace - element and isotopic data , and some petrochemical , trace - element and isotopic diagrams widely applied to the identification of geo tectonic environments , authors recognize that guidong granitic massif was emplaced in post - orogenic collision environment
  摘要本文在研究贵东花岗岩岩体岩石矿物组合、结构构造等地质特徵的基础上，运用花岗岩的岩石化学、微量元素和同位素等分析数据，采用目前广泛应用的几种岩石化学图解、微量元素和同位素图解等方法，判别了贵东岩体形成的构造环境?造山带后碰撞型。
• Bold lane was included in the magazine ' s list of the world ' s top ten secure places , along with more established sites such as the fort knox bank vault , which boasts a 25 - tonne door and granite walls , and the baghdad bunker used by deposed iraqi leader saddam hussein . " we didn ' t want to fill the list with banks and bases
  鲍尔德路停车场跻身于该杂志所列的世界十大安全地点,其中有诺克斯堡金库这样更知名的地方(该银行声称自己有25吨重的门和花岗岩的墙) ,以及已被废黜的伊拉克领导人萨达姆曾使用过的巴格达地堡。
• The zircon shrimp u - pb dating results suggest that the qiongzhong and danxian granites were emplaced at 237 3 ma and 186 3 ma , respectively , which argued against the previous thoughts that all the foliated granites with orientated structure in hainan island formed duing the hercynian - indosinian episode
  高精度shrimp锆石u - pb定年显示琼中岩基形成于印支期( 237 3ma ) ，而儋县岩基形成于燕山早期( 186 3ma ) ，修正了前人将海南岛具有定向构造的变形花岗岩等同于海西?印支期花岗岩的认识。
