灾害

Wind hazard is the one which has the widespread influence in the nature disaster , and hurricane hazard is the most devastative and disastrous one.

风灾是自然灾害中影响非常广泛的一种，其中台风灾害又是风灾中破坏力最大、造成损失最严重的一种。

As to the model of legislation,it s best to take the mixed model,e.g.center and multiplex legislation,including the law of dipartite underground superficies,the law of requisition of underground space,the law of registering the underground real estate,the basic law of underground building,the law of programming on the underground space,the law of the promotion of usage of undergr...

我们要建构地下区分地上权法、地下征收征用法、地下登记法、地下建设基准法、地下空间规划法、地下空间利用促进法、大深度法、地下环境保护与灾害防治法等。在建构的进程中应该走综合化的道路，尽量中央立法和复合立法。

During the process of the fore mentioned analyses, some tentative works as follows were done.(1)On the basis of the fundamental of spatial analytic geometry, the basic method for displaceable block searching was put forward and the relevant program was written. With this program one can easily search out all the displaceable blocks and omitting of blocks, which is very common in searching blocks manually, can be avoided.(2)The coefficient of stability of blocks with failure mode II-2(that is, sliding on a single sliding surface, but confined by near intersecting line )was deduced.(3)The multi-cavern effect of Laxiwa underground caverns was studied on the assumption that all of the caverns were full face tunneled at the same time.(4)The stability classification scheme of rock mass surrounding large scale underground caverns was established. In addition to inherit the merits of the method of engineering geological

在完成上述工作的过程中，本论文主要在以下几个方面进行了一些探索：①基于空间解析几何原理，提出了块体搜索的基本思路并编制出相应的程序，基本实现了块体搜索的自动化，既大大缩短了块体搜索时间，又能防止因人工搜索引起的遗漏；②推导出Ⅱ-2型(单滑面滑动，但受侧限面约束)块体的稳定性系数计算公式；③以数值模拟方法论证了拉西瓦地下厂房洞室群全断面一次开挖时群洞效应的具体特点；④以岩体质量、开挖效应、群洞效应和次生灾害效应为评价指标，建立了&大型地下洞室群围岩稳定性分类&方案；该方案既继承了水电行业规范&围岩工程地质分类&法的优点，又综合考虑了大型地下洞室群的工程特点。

Corrosion process of water flow could have great impact on dissolvable rock area in several decades.

岩石风化作用既是地壳固体物质形态转变的重要途径，也是产生块体运动灾害的必要前提条件，其类型和强度受区域气温及降雨条件的控制；水的侵蚀作用的区域性规律受地貌成因和气候条件的制约，它对陆地环境的最大冲击是对海洋、湖泊及水库岸滩带的侵蚀和改造；流水的溶蚀作用可在几十年内对可溶岩类地区产生影响。

The Lake area in Jianghan Plain is one of the most ecotypically fragile areas in Yangtse Valley, and here there are four main ecological problems: frequent flood, silt and sand that make the lake become a swamp, water pollution and eutrophication, and the schistosome.

江汉平原湖区是长江流域生态环境最脆弱的地区之一，洪涝灾害严重、泥沙淤积和沼泽化现象普遍、湖泊水体污染与富营养化问题突出、血吸虫未得到根治等是该区目前存在的主要生态环境问题。

These have important academic and realistic value to study the connection between the coal and rock failure and EME, and to prevent and control the dynamic catastrophe of the coal and rock.

这对于搞清煤岩破坏与电磁辐射之间的关系，防治煤岩动力灾害具有重要的理论和实际价值。

Endogenetic causes are a great contributor to hazard creation.

许多内生的原因，对灾害的产生也起着重大作用。

Thank you again for your attention and warm heart, our donation program have being under progress. Your energetical participation is warm expected. We hereby look forward to calling for your extending strong hands to exhibit our confidence, courage and national cohesion. Let's join hand together to make the success in the resue on the earthquake!

再次感谢大家的关注与爱心，我们的捐款活动还在大力进行之中，在此希望大家踊跃参与，献出您的爱心与援助，在突发灾害面前展现出我们的强大信心、勇气和团结，早日赢得抗震救灾的胜利！

Secondly, because of estrepement, denudation, repeated alternation of cultivating and stockbreeding, and irrational usage of water resource, calamities took place frequently in the whole of Yellow River valley, which did very harm to people's producing and living.

其次，西北农业开发中由于滥垦、滥伐，农业、畜牧业反复交替，水资源利用不合理，造成整个黄河流域灾害频发，给人民生产和生活带来严重影响。

The tectonic activities are so strong that a large number of faults and folds are formed in the area. Under coupling of the endogenic and exogenic geological processes, there are many loose Quaternary deposits, and they are the main carrier of most geological hazards.

在青藏高原隆升及气候变化等内外动力作用下，研究区内堆积体分布广泛，具有独特的工程地质特征并成为该区内地质灾害的主要物源。

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。
