With the swift development of the hydroelectric project in our country, a set of large or extraordinary hydropower stations are being designed or constructed, such as the Three Gorges hydropower station, Longtan hydropower station, Xiangjiaba hydropower station, Xiaowan hydropower station, Pengshui hydropower station etc. All these hydropower stations adopt underground workshop, and have long diversion pipe system, and have one or two surge-chambers or adopt tailrace tunnel with sloping ceiling.

随着我国水电事业的迅速发展，一批大型、特大型水电站正在设计或处于待建之中，如三峡水电站、龙滩水电站、溪洛渡水电站、向家坝水电站、小湾水电站、乌江彭水水电站等，这些电站多采用地下厂房，具有较长的引水发电系统，并且设有调压室或采用变顶高尾水洞。

When the earthquake occurred, high-rise buildings of glass and concrete building lateral fragments, and advertising signs, tinplate board, Nihong Deng-, may fall wounding, walking in the street, will be the best side of the bag or Top soft goods in the head, no item can also be in the head with their hands for as much as possible for self-defense preparations to be calm, should quickly leave the poles and the wall, toward a broader regional escape.

地震发生时，高层建筑物的玻璃碎片和大楼外侧混凝土碎块、以及广告招牌，马口铁板、霓红灯架等，可能掉下伤人，因此在街上走时，最好将身边的皮包或柔软的物品顶在头上，无物品时也可用手护在头上，尽可能作好自我防御的准备，要镇静，应该迅速离开电线杆和围墙，跑向比较开阔的地区躲避。

Also, during this process, the water content in vegetation increases and keeps stable gradually, and the water environment in ecosystem will become suavely.

摘 要：本文以南亚热带常绿阔叶林为基本，同时探讨了热带南亚热带森林演替系列中8种生态系统类型的水分结构，发现植被水分结构的恢复与土壤水分结构的恢复是不同步的，50a以上没有受扰动的土壤，其土壤水分结构在时空上才趋于稳定；植被水分结构的时空稳定性基本上与生态系统的演替状况一致；为满足植被蒸腾的需要，植被中水分的月更新次数随着群落向顶极系统的演替而逐渐减少。

In practice, however, it is rare for reefs to have both such indications. An obviously abnormal reflection has been found in the Jiannan structural unit, Shizhu synclinorium. From the analyses of depositional cha...

在石柱复向斜建南构造带上，发现了长兴组顶一个很明显的异常反射，通过礁体的沉积特征、地震相特征及AVO响应特征对该异常反射进行全面分析，认为很可能是礁的异常反射，但有待钻井最终验证。

Anaerobic synecology of the hydrogen-producing fermentation system was investigated under certain test condition in this thesis. In the continuous flow system of anaerobic hydrogen-producing fermentation, the succession of hydrogen-producing acidogenic microbiology may be regressive process. By regressive process we means that the original community getting from nature which structure being complex with a high ability would degenerate gently to a certain climax community which structure being simple with less ability.

产氢发酵系统的微生物群落生态学研究证明，在连续流发酵产氢反应系统中产氢产酸发酵细菌群落的演替过程，是在人为控制的生境条件下，微生物从自然群落这种稳定性大、组成及生化反应过程复杂的生态群落，向稳定性小、组成和生化反应过程相对简单的某一产酸发酵顶极群落进行的"逆行演替"。

Observing the ceiling of the Sistine Chapel and the hugely familiar and awkward encounter between Michelangelo's God and Man through their index fingers, Tallis identifies an intuitive indication of the central role of the index finger in making us unique.

其中《创造亚当》是整个天顶画中最动人心弦的一幕，这一幕没有直接画上帝塑造亚当，而是画出神圣的火花即将触及亚当这一瞬间：从天飞来的上帝，将手指伸向亚当，正要像接通电源一样将灵魂传递给亚当。

I have a row of teeth, root Department prominent lips were feeling out on top, there are ways to correct it?

我上面一排牙齿，牙根处比较突出，感觉上嘴唇被向外顶，有办法矫正么？

In addition, total wheel/rail contact calculation with divided rail outline method are raised. Under the condition of considering the displacement, bouncing, yaw, roll of wheelsets and displacement, bouncing, roll of rails, minimum gap between rail and wheel were calculated by the trochoid method and divided rail outline method, we can easily judge totally real contact states of the wheel/rail such as normal one-point contact, nonnormal one-point contact, two-point contact and wheel complete lift. Wheel/rail normal forces in the two contact point are respectively calculated by nonlinear Hertz contact theory, and then, result of simulation more close to reality on actual track.

另外，提出了轨廓分区法全面计算轮轨接触状态法，在考虑轮对的横移、浮沉、摇头、侧滚和左右钢轨的横移、浮沉、侧滚的条件下，可全面地分别计算左右侧轨顶和轨侧区域与车轮的最小轮轨间隙量，以此来判断轮轨的真实接触状态：正常的一点接触、非正常的一点接触、两点接触和车轮完全悬浮，并根据非线性赫兹接触理论分别求得两接触点处的轮轨法向力，从而使仿真结果更接近于车辆在实际线路上的运行状态。
