But detail geochemical study indicates (Wu et al., 2002)that those rocks have low Sr〓(0.706), high ε〓(-0.5～-1.9), young age of Nd model age (970-1090Ma) and syngenesis with surrounding I-type granites. The rock originated from partial melting of source igneous rock and belongs to I type granites. The occurrence of high alumina minerals is related to the intense interaction of magma and liquid during the late period of magma evolution, and tetrad REE patterns are formed.

但详细的地球化学研究表明(Wu et al。，2002)，岩体具有低的Sr〓(0.706)、高ε〓(-0.5～-1.9)、年轻的Nd模式年龄(970-1090Ma)及与周围Ⅰ型花岗岩的共生关系，认为岩体是火成岩源岩物质部分熔融的产物，属于Ⅰ型花岗岩，高铝矿物的出现与岩浆演化晚期强烈的岩浆—流体相互作用有关，并形成特征的稀土元素四分组效应。

The results show that the radial stress and tangential stress with considering the influence of seepage water pressure are larger than those without considering the influence, and this makes the plastic zone of surrounding rock expands. When the seepage factors of surrounding rock and liner are obviously different, they are not simplied as one and the same.

计算表明，当考虑渗透水压力作用时，围岩径向应力和切向应力都增大，并使围岩塑性区扩展；当隧洞围岩、衬砌材料的渗透系数差异显著时，不能简化为等渗透系数处理。

Based on the Inglis formula, which calculates the tangential stress of the surrounding rock of geological stress field in different circumstances, programme is developed to compute the corresponding tangential stress of the surrounding rock of several underground plants, for instance, Ertan project of Sichuan according to different directions of longitudinal axle.

从地下洞室周边切向应力的英格里公式出发，提出针对不同环境的地应力场进行地下厂房纵轴线方位优选的简便方法，并编程计算了四川二滩等多个地下厂房不同纵轴线方向所对应的洞室周边切向应力，分析不同纵轴线方向条件下洞室周边切向应力的极值，并与实际工程所选取的纵轴线方向所对应的切向应力值比较，讨论了工程所选纵轴线的合理性以及洞室周边应力的集中程度。

Rock point load test is a simple and effective way to test rock strength.

点荷载试验是测定岩石强度的一种简单有效的方法。

By the study, after the tunnel is timbered as the original designation, the plastic scope of the surrounding rock's distortion is controlled obviously, and the stability of surrounding rock is strengthened.

通过研究认为，隧道按原设计方案支护后，围岩的变形及塑性区范围得到明显控制，增强了长子面围岩的稳定性。

Take different timbering kind to the different country rock of iron ore of boreal 洺 river and place, assure the stability of country rock effectively.

对北洺河铁矿的不同围岩和部位采取不同的支护方式，有效地保证围岩的稳定性。

Based on active timbering principle of bolt-grouting, shearing strength between bolt-grouting and rock can be transformed into the surface pressure of acting on the inner surface in the cavity and anchor-forced rock is regarded as a equivalent material.

3基于锚杆的主动支护原理，将锚杆与岩体之间的剪应力转换为作用在洞室内表面上的面压力，将锚固后的岩体视为等效材料。

Based on the geoengineering view , started with investigation of engineering geology of rock mass surrounding the roadway, the mechanical deformation mechanisms of the high stress weak rock in Tonger mine have been researched.

本文运用地质工程观，从巷道围岩工程地质研究入手，研究了通二矿高应力软岩的变形力学机制。

From the heart I can tell no lies From the heart I can tell no lies, lies, lies Like Lennon said for me I believed in Ray and Keef Like Townshend said for me Rock and Roll made me free From the heart From the heart From the heart Rock and Roll made me free From the heart From the heart From the heart No lies

从心里我可以告诉从没有谎言心我可以告诉任何谎言，谎言，谎言像列农表示，我相信和我一样唐申德基弗在雷石辊，为我说，让我自由的从从心从心摇滚心使我心自由从心从从心无谎言

Townshend is the primary songwriter for The Who , writing well over one hundred songs for the band's eleven studio albums, including the rock operas Tommy and Quadrophenia and the well-regarded rock radio staple Who's Next, plus dozens more that appeared as non-album singles, bonus tracks on reissues, and tracks on rarities compilations such as Odds and Sods.

汤森是谁人，写了超过100乐队的11张专辑，包括摇滚歌剧歌曲和歌手小学和汤米和Quadrophenia广泛关注的摇滚电台主食谁下，加上几十这似乎非专辑单曲，奖金轨的再版，并追踪在稀有汇编，如赔率和草皮。

I can not make it blossom and suits me

我不能让树为我开花
