First, select four kinds of main risks source from bigly celebrate the main risk in region source, namely the flood, drought, sand-dust weather and petroleum pollution accident, etc. According to the different a request for to habitat, study this 19 kinds of landscapes ecosystem type of the Regional induce for 7 kinds of ecosystems system: Then the marsh of bulrush, lakes and reservoirs , salt alkali wasteland, prairie, island form wood, farmland, town. The difference is proceeded by characteristic according to each type ecosystem to the analysis of four kinds of main risks source, including the certain risk all rate, delimiting the space distribute, analyzing the risk strength to the receptor etc. At proceed the revelation the different from endanger to analyze the inside, this text borrows ecosystem index number that this index sign to reflect primarily habitat the ecosystem meaning of the type of habitat the different from position, with weak an index number to show the destructibility of the habitat, from but compute each ecosystem that is lost by ecosystem system an index number.

首先，从大庆地区主要的风险源中遴选出四种主要的风险源，即洪涝、干旱、沙尘天气和石油污染等；依据不同生物类群对生境的要求，将本研究区域的19种景观生态类型归纳为7种生态系统：即芦苇沼泽、湖泡库渠、盐碱荒地、草甸草原、岛状林、农田、城镇；对四种主要风险源的进行分析，包括确定风险概率，划定空间分布，对风险受体的作用强度分析等；在进行暴露和危害分析中，本文主要借生态指数这一指标来反映不同生境类型的生态意义和地位，以脆弱度指数来体现不同生境的易损性，从而计算出各受体生态系统的生态损失度指数；由于各主要风险物质对风险受体的作用强度是不同的，对形成区域性生态风险的作用大小也有差异，因此本文采用层次分析法对主要生态风险物质进行综合评价，并把判断矩阵排序权值的合理计算问题归为—非线性化问题，并提出用基于遗传算法(GA[5])的层次分析模型进行权重分析；进行风险表征，即综合前面两个阶段的信息，对环境中风险的性质和强度以及风险评价过程中不确定性问题进行分析与描述，并划分出五级生态风险区；最后，根据划分的五级生态风险区的特征，分别提出针对各生态风险区的生态风险管理对策。

Dynamic reliability under Littlewood-Paley wavelet is the biggest, dynamic reliability under modified meyerwavelet and harmonic wavelet are close. Analyzing the dynamic reliability of structure under odd exponent wavelet is very simple, it doesn't calculate Power Spectral Density function integral, it is only to calculate the square of displacement standard deviation and the square of velocity, then the dynamic reliability of structure can be concluded by max distribution. In addition the effects of upper limit is considered, when upper limit is smaller, the dynamic reliability of structure is less, that is, the damage possibility is bigger.

通过结构地震反应在小波基下的动力可靠性分析说明：无论是单自由度还是多自由度从理论上推导在这四种小波下的结构动力可靠性是可行的，而且考虑的结构地震反应都是非平稳的高斯过程，方法实现也比较容易；在Littlewood—Paley小波基下求得的结构的动力可靠度比较大，由改造的meyer小波和谐波小波求得的动力可靠度略有差异；单边指数小波下的结构动力可靠性分析非常简单，不用求功率谱函数来积分，只需求得结构地震反应的位移方差，速度方差，利用最大值分布公式就可得到结构的动力可靠时程；另外也考虑了超越界限对结构动力可靠度的影响，超越界限越小，结构的动力可靠度越小，即破坏概率越大。

The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.

结果表明：各物种的热值动态变化规律并不是统一的，这种变化可能与植物各器官热值的变化及生殖期出现的时间有关；各植物器官的热值普遍表现出穗的热值大于茎和叶；水生植物的热值明显小于中生性和湿中生性植物；种内热值变化随物候期变化有一定的规律，大约会出现2次低值、2次高值；种间热值差异是由于植物本身性质决定的，在相同生境和气候条件下，植物体中含能物质越多，就越易积聚热值，从而更适宜生长在此环境。

And to contact the Chinese old civilization to our gallery,made it to be a special one.We deeply believed that the more a cultural innovation emerged one after another,the more muti- environment and tolerate of the civilization to be needed.We encourage the art works which span the culture,language,space, gender as well,and try ours best to extend the artists who made great efforts to it.We also put focus on training chinese collectors,let more arts' fans have their own consume conception in art area.

我们深信越是文化的创新层出不穷，越是需要文化语境的多元和宽容，我们将鼓励跨越文化，语言，空间，性别等差异的艺术作品的创作，并不惜代价的在国际上推广这些为此付出努力的艺术家，我们还将在培养中国本土收藏家群体上做出自己的努力，让更多的人在文化的消费上有自己的主张。

The differences of the micro structure and properities of the bulk sinters, between the fabrication methed of powder metallurgy and reactive synthesis for silver tin oxide composite, are studied in prensent thesis. With the increase of the tin oxide content in silver matix, the electric conductivity of the composite tended to decreace. While in the same tin oxide content, the electric conductivty of the composite fabricated by reactive synthesisis better than that by powder metallurgy. One of the reasons is that the regular net structure existing in former composite.

研究了两种方法即粉末冶金法和反应合成法制备的银氧化锡复合材料烧结坯在组织上的区别和性能上的差异，两种方法制备的银氧化锡复合材料，随着氧化锡含量的升高，材料导电性均呈下降趋势，而相同成分的材料，反应合成法制备的银氧化锡复合材料的烧结坯的导电性要优于粉末冶金法，有规则的网络状组织结构是反应合成法制备的烧结坯导电性好的原因之一。

Notwithstanding all these objections, however, it can not be denied that various portions of Genesis palpably convey the impression of difference in origin and a corresponding difference in conception; but as the impression that the work gives of having been uniformly planned in every detail is still stronger, the explanation given in § 2 is here repeated; namely, Genesis has not been compiled from several sources by one redactor or by several redactors, but is the work of one author, who has recorded the traditions of his people with due reverence but independently and according to a uniform plan.

尽管所有这些反对意见，但是，不能否认，成因各个部分的印象明显差异来源和相应的不同的概念，但作为一种印象，即工作提供了统一的计划在每一个详细仍然强大，解释在第2条在这里重复；即成因尚未汇编从几个来源之一redactor或几个编纂，但工作的一位作者，谁都有自己的传统的人因为敬畏，但实行独立，并根据统一的计划。

But after an audacious Shuttle repair mission, when Hubble was fixed with what is effectively a pair of eyeglasses to correct its sight, the telescope has returned some of the most stunning images ever captured by science.

但是通过有危险性的航天飞机运载技术工人维修后，哈勃望远镜被装上了类似于人类眼镜的装置，装置起到了积极的作用，较正了镜头的透光，望远镜所拍摄的图像的质量与之前一些被用作科学研究的图像相比没有任何差异

The percentage of strong positive expression of MUC2 in SSDH group, slightly higher than it in SSW group , which may indicate a diminishing trend of the expression of MUC2,which might prompt the direction of the development of the disease ,and could provide a valuable signal on the disease prognosis and treatment.

脾胃湿热组、脾胃虚弱组MUC2表达无显著性差异，但脾胃湿热组MUC2的强阳性表达率较脾胃虚弱组略高，这可能说明脾胃湿热证和脾胃虚弱证之间粘蛋白的表达呈递减的趋势，即肠粘膜的防御保护功能下降，而这种递减可能提示了疾病发展的方向，可能对疾病的转归及临床治疗提供有价值的预示。

"Epidemiological studies hae shown a temporal and geographic ariability in the occurrence of RA in dierse populations," Dr. Oili Kaipiainen-Seppanen and colleagues from Kuopio Uniersity Hospital, Finland, write."The annual incidence lies between 25 and 50/100,000 in most Western populations."

&流行病学研究表明在不同的人群中RA的发病率有暂时的和地理性的差异，&Oili Kaipianen-Seppanen博士和他的来自芬兰Kuopio大学附属医院的的同伴写道：&在大部分西方人群中每年的发病率都在25/1000000到50/100000之间。&

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
