Athanasius that in 331 the saint enjoined upon his flock a period of forty days of fasting preliminary to, but not inclusive of, the stricter fast of Holy Week, and secondly that in 339 the same Father, after having traveled to Rome and over the greater part of Europe, wrote in the strongest terms to urge this observance upon the people of Alexandria as one that was universally practiced,"to the end that while all the world is fasting, we who are in Egypt should not become a laughing-stock as the only people who do not fast but take our pleasure in those days".

在任何情况下，它是某些从"节日快报"圣亚他那修，在331圣责成他的羊群时，为期四十天的禁食初步，但不包括，严格快速的圣周，第二，在339个同一个父亲，之后前往罗马，在更大的欧洲的一部分，写以最强烈的措词敦促遵守各国人民的亚历山德里亚的一个普遍做法是，"到最后，虽然世界上所有的空腹，我们谁是在埃及不应成为笑股票作为唯一的人谁不采取迅速，但我们很高兴在那些日子里"。

In any case it is certain from the "Festal Letters" of St. Athanasius that in 331 the saint enjoined upon his flock a period of forty days of fasting preliminary to, but not inclusive of, the stricter fast of Holy Week, and secondly that in 339 the same Father, after having traveled to Rome and over the greater part of Europe, wrote in the strongest terms to urge this observance upon the people of Alexandria as one that was universally practiced,"to the end that while all the world is fasting, we who are in Egypt should not become a laughing-stock as the only people who do not fast but take our pleasure in those days".

在任何情况下，可以肯定的，由"节日字母"圣athanasius在331圣人受命后，他的羊群，为期四十天的斋戒初步的，但不是包容的，更严格的快的圣周，其次是认为在339个同一个父亲，之后前往罗马，并在更大的欧洲的一部分，写以最强烈的措辞敦促遵守本后，人的亚历山德里亚，作为一个被普遍实行的"，至去年底，虽然世界上所有的是斋戒，我们是在埃及不应成为一个笑柄，因为只有那些没有速度快，而且以我们最大的荣幸，在那些日子"。

In 2000,the area below 400 meters was also watershed,mining sites and settlements,the proportion of both unutilized land below 400 meters and woodland between 400 meters and 800 meters raised a little,it showed that most woodland transform into the other types of land use in low altitude area,however,most unutilized land and the other types of land use transform into woodland in low and mediad altitude area,and the changes in woodland had metastatic trends in low and middle altitude area in the years from 1988 to 2000.The area proportion between 400 meters and 800 meters raised a lot in mining sites and settlements,the total distributed area on woodland had a trend of rising,while the distribution in pasture had a trend of decreasing.

在2000年，400m区域以下依然是水域和居民点及工矿用地，未利用地比例在400m以下有所上升而林地比例在400m～800m有所上升，表明在1994年至2000年间，低海拔地区许多林地转化为其他土地利用类型，而在中低海拔地区大量的未利用地和其他土地利用类型转化为林地，林地的变化有向中低海拔转移的趋势。2006年居民点及工矿用地在400m至800m区域面积比例增加，林地类型分布区域整体呈上升的趋势，草地分布区域呈下降的趋势。

This thesis takes the strenuous search for cultural identity of the Dead family in Song of Solomon as the main line, embarks on the cultural identity of blacks in different periods, connects the pursuit of identity with their history in American society, outlines a vivid historical picture of blacks from the evolution of their identity (from the enslaved black to the emancipated freedman, to the northern migrator and then the youth born in the north), further explores the efforts made by the blacks on their way to seek their national outlets and build their cultural identity in different periods, points out the advantage and disadvantage of their choice, and finally draws to the conclusion that African American should not abandon their national tradition but at the same time they must stand on American society and find a sound integrity of the two cultures.

本论文以托妮·莫里森的第三部小说《所罗门之歌》中戴德家族寻求文化身份认同的艰难历程为主线，以黑人在不同的历史时期的文化身份的选择为切入点，把黑人对身份的探寻与他们在美国社会中的历史文化联系在一起。从黑人身份的演变(从奴隶到被解放的自由人到北方移民者到出生在北方的新一代黑人青年)勾勒出一幅美国黑人百年历史的生动画面，分析在不同时期黑人为寻求民族出路和构建文化身份时所做出的艰苦卓绝地努力和探索。同时也指出了他们所选择道路的利与弊。最后的结论是：在寻求种族出路时既要立足美国现实又不能抛弃种族传统，而应该努力找到二者的最佳结合点。

An. minimus A and C can be visually distinguished according to the specific bands in agarose gel. For ASA, specific bands of 294bp and 112bp represent An. minimus A and C, respectively. In RFLP, three fragments of 376bp, 268bp and 108bp were observed for An. minimus A, while only a band in 376bp for An.

在PCR-ASA在PCR-ASA中，两亲缘种除在376bp处均有一条条带外，分别在约294bp和112bp处出现各自的特异扩增带；PCR-RFLP的结果是，微小按蚊A在约376bp、268bp和108bp左右出现3条条带，而微小按蚊C仅在376bp处存在唯一条带。

Centrifugal energy saving analysis and measures: 1 improve the efficiency of centrifugal pumps a first step, in the selection of comparison, when many suppliers Selection program, in considering the cost-effective choice as far as possible under the premise of efficient programs; the second step , accredited professionals must Mill producers, affecting the pump efficiency of the key components such as impellers, pump body, pump cover, diversion devices, such as the manufacture of quality producers, especially for the airfoil impeller , outlet angle, leaves the sub-degrees, the shape of flow channel, to control the quality of finish, etc., so that products are delivered in the current production under the conditions of highly efficient products; the third step, the scene in the production of installation and debugging process, pump to ensure a solid foundation, with the driving machine for good, before and after valve flexible piping layout design is reasonable, on-site control is feasible and safe, the complete and accurate monitoring instrumentation to ensure that pump operation can carry out real-time monitoring; fourth step , are at long-term operation of water pumps necessary to pay attention to the equipment inspection and found anomalies reflect real-time reporting, in the normal minor repairs, overhaul cycle, to deal with the replacement of wearing parts inspection to ensure the pump's long-term safe and efficient operation.

Based on the existed research, the study found that the selection of these subjects have rarely been studied, so the selection of this theme has significance in the information society geography theory and can rich the tourist sites in geography study and can guide new thoughts. The second part discusses distance decay effects in web sever when attenuation theory be chose in electronic age location. It considers 7 factors: knowledge spillover environment and yi to technological innovation information reaches nature, decision-maker behavior,human capital factor, supply chain environment, yi to the developed communication net and network of communication lines reaches nature, agglomeration factor, commercial and trade circumstance. Part three studies location significance of outdoor sports websites. Though investigating and analyzing our country 30 cities's outdoor sports websites in China, the author gives out the location characteristics of outdoor sports websites in actual geographical space, and take Shijiazhuang for example, the author analyzes the stadiums gathering effection to the outdoor sports websites which are near the stadiums, and dividing the location into gathering area and non-gathering area the author studies the effects for information flow guiding people flow. Part four is the conclusion which includes four conclusions reached by this article.
