Tunnel project started from the end of July 2009, has been the company's leaders are most concerned about one of the items. No. 1 tunnel construction more smoothly, was run through January 13 of this year. No. 2 tunnel construction process, there are many uncertain and unpredictable factors, imports of concrete lining of 228 meters, the rock formation is marl, landslides serious digging edge to edge supporting, progress is slow.

隧道工程自2009年7月底开工以来，一直是公司领导最关心的项目之一。1号隧道施工比较顺利，已于今年1月13日贯通。2号隧道施工过程中，存在很多不确定和不可预见因素，进口砼衬砌228米，岩层是泥灰岩，塌方严重，采取边挖边支护，进展缓慢。

This study provides a useful mean for studying the distortion or failure of the marlite slope.

If there are gypsum or thick marlite intervals, bright spots and low velocity anomalies may appear.

当飞一—飞三段内发育有膏盐层或较厚的泥灰岩段时，也会形成"亮点"反射或低速异常体，如果只靠常规剖面或速度反演，就可能造成误解。

The results show that the karstification of marlite is influenced by many different factors. Joints and fissures are the most important factors. Different karst morphs come into being during the karst process, including twig-like, ring-shaped, radial pattern, beading-shaped, dispersed and biologic shell shaped ones.

结果表明：泥灰岩的溶蚀作用受不同因素的影响，特别是受节理裂隙发育的影响，形成多种不同的溶蚀形态，包括树枝状、环状及放射状、串珠状、分散状和生物壳状。

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.

对于江汉盆地西缘宜昌地区来说，其沉积及古地理演化表现为：早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境，沉积中心在天阳坪断裂的北侧，此时几乎不存在来自黄陵地区的水系；晚白垩世同样为受断裂控制的内陆湖盆环境，但湖盆面积扩大、断裂活动减弱，且后期出现成化湖相沉积；第三纪早期盆地由断陷盆地转变为坳陷盆地，同时石膏的出现代表了局限咸化湖盆的存在；渐新世—中新世，受构造影响，缺失该时期的沉积；上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在；早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积，早更新世晚期—中更新世早期为扇三角洲—湖相沉积，后期出现沉积结束以后的网纹红土化作用。

The main sedimentary facies types include shoal facies of platform margin, organic reef facies of platform margin, platform evaporate facies, open-platform facies, restricted platform facies and carbonate platform ramp facies, and the front three types of facies are the uppermost facies belt. The main sedimentary microfacies types include subordinate organisms dolomite microfacies, sparry grain(biogenic debris, sand cutting, alga chippings and so on) dolomite microfacies, detention gravel debris dolomite microfacies, boundstone microfacies, non-lamina dolomite mudstone microfacies, lamina dolomite mudstone microfacies, lamina lime mudstone microfacies, sparry grainstone microfacies and testaceous chippings limestone microfacies, and the front three types of microfacies are the uppermost microfacies type.

该区长兴组主要的沉积相类型有台地边缘浅滩相、台地边缘生物礁相、开阔台地相、局限台地相、台地蒸发岩相和碳酸盐台地缓坡相六个相带，主要的微相类型有生物粘结云岩微相、亮晶颗粒云岩微相、滞留角砾云岩微相、纹层纯云泥岩微相、非纹层纯云泥岩微相、生物粘结灰岩微相、纹层纯灰泥岩微相、亮晶颗粒灰岩微相和介屑灰岩微相九种微相类型。

The rock types include limemud limestones, bioclast limestones, oolites, intraclast limestones and dolomites, indicating a typical set of epeiric sea carbonate platform or submerged platform deposits.

岩石类型包括泥晶灰岩、生物碎屑灰岩、鮞粒灰岩、內碎屑灰岩、白云岩等，为一套典型的臺地或沈没臺地型陆表海碳酸盐沈积。

Marlstone samples from the Early Cretaceous Shangkuh Formation in the Jianzishan section and geological pits in Dawu＇ergen were analyzed systematically using the polarizing microscope, fluorescence microscope and freezing-heating stage.

利用偏光显微镜、荧光显微镜和冷热台对大乌尔根尖子山剖面和地质浅井早白垩世上库力组的泥灰岩样品进行了系统研究。

Stoneworts contain calcium carbonate deposits so extensive that they may form the major part of lake bottoms.

轮藻形成碳酸钙沉淀，这些沉淀可形成湖泊钙质泥灰岩的主要成分。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
