The most serious desertification occurred in southeast of MuSu Desert,then appeared inferior degree in midst,north,south and east,anddegression degree in other directions.6.The changes of environment in Mu Su Desert in historical times havebeen controlled by climatic changes in temperature and drought-wetwithin hundreds or thousands years.At present,it came into being suchspatial structure and environmental characteristics fordesertification land because of being relative to other naturalgeographic characters and human activities.In all that,physiognomyand hiemal wind are the driving factors.The sandy matter in stratumis the physical fountain factor.The depravation of surface water inthis region is one of representations of environmental changes, meanwhile,it is also the factor which leads to the degradation ofvegetation and desertification.On the whole,human activity has actedupon these natural elements,becoming a dominant factor in the regionalenvironment changes since Ming and Qing dynasty.7.Influencing of human activities on the environment of Mu Su Deserthad occurred before Qin dynasty,and its intensity of earlier influencewas so slight that it could not cause a large scope and long timeenvironmental changes.

沙漠化的程度是东南部最强，中北部、南部和东部次之，而后向其他方向递减。6、毛乌素沙地历史时期的环境变化是受百年乃至千年尺度的气候冷暖、干湿变化控制的，之所以形成目前这样的沙漠化土地空间分布格局和环境特征，则与其地的自然地理特征和人类活动有密切关系，其中地貌及冬季风是动力因素；地层中的沙物质是物源因素；地表水环境恶化是区域环境变化的表现之一，同时又是植被退化和沙漠化的引致因素；人类活动总体上是叠加在自然因素之上的，只是明清以来在局地环境变化中成为主导因素。7、毛乌素沙地人类活动的环境影响在先秦时期就已出现，早期的影响程度是轻微的，不足以造成大范围、长时段的环境变化。

The new technique reduced the distance ladder to three "rungs":(1) The distance to galaxy NGC4258 is measured using straightforward geometry and Kepler's laws;(2)Cepheids in six more distant galaxies are used to calibrate the luminosity of Type Ia supernovae;(3) The Hubble constant is measured by observing a brighter milepost marker, Type Ia supernovae, in more distant galaxies hundreds of millions of light-years away, embedded in the expanding universe.

这种新技巧简化了距离跳跃为三个&阶梯&：1、星系NGC 4258的距离采用开普勒定律和简单直接的几何方法精确测量；2、在6个更远的星系中的造父变星用来校准Ia超新星的光度；3、深嵌于数亿光年外的膨胀宇宙中的星系中的Ia超新星——一种遥远而明亮的量天尺，被用于精确测定哈勃常数。

According to the domain organization, the GGDEF-EAL containing proteins (pfam database, version 17.0) were classified into A and B types. Six hundreds and five of the 621 proteins were in A type, which was also found in the ancient bacteria Aquifex aeolicus VF5 suggesting that this is the ancestor of the GGDEF-EAL proteins. Phylogenetic analysis of GGDEF- and EAL- containing proteins in the genome of V. vulnificus YJ016 revealed that GGDEF-EAL proteins were clustered. Comparative analysis of domain organization of the clads in the EAL tree allowed identification of several duplication events. The results indicated that most of the GGDEF- and EAL- containing proteins arised by gene duplication.

根据pfam资料库(Version 17.0)，我们整理同时拥有GGDEF和EAL功能性区域的蛋白质，这些蛋白质可以被区分成两种型态，在总数621个GGDEF-EAL中有高达606个是A型态，而且它在古老的细菌Aquifex aeolicus VF5的基因体中也能找到，因此我们推测它可能是GGDEF-EAL的袓先，藉由分析创伤弧菌中所包含之GGDEF和EAL的演化关系，大部份的GGDEF-EAL会群聚在树型相近的位置，进一步比较在EAL树型上有邻近关系的蛋白质序列，根据他们的长度、与所包含的功能区域，我们找到了一些重制的演化痕迹，这样的结果指出，目前看到大多数的GGDEF 和EAL可能都是经过重制产生。

As we have learned, in the 263 computer rooms that have independence in Chang Ping, the deploy in the computer room 4 Cisco grade of class of 12000 series telecommunication by implement, the EMC memory server with the most advanced whole world and generation set of hundreds UPS, derv and quite bit server of the amount, investment exceeds 100 million yuan.

据了解，在263在昌平拥有独立的机房，机房中部署了四台思科12000系列电信级路由器、全球最先进的EMC存储服务器以及数百套UPS、柴油发电机组以及相当数量的刀片服务器，投入超过亿元。

In August that year, the 32nd International Geological Congress was convened in Florence, Italy. Oral presentations and posters made by hundreds of geologists and geopark administrators from scores of countries of five continents demonstrated the current situation of geoheritage conservation, geoscientific researches on geoheritages, public education, methods and technology of protection, the relations of geoheritages with cultural heritages, with development and planning of cities and regions, and with the development of tourism, the relations between geoparks and national parks, the prospects of geoparks in Europe, America, Africa, Australia and Asia etc.

在2004年6月在中国北京召开了第一届世界地质公园大会和2004年8月在意大利佛罗伦萨举行第32届国际地质大会，来自五大洲数十个国家的地质学家和地质公园管理者发言，展示了各国地质遗产保护现状，地质公园建设中地质遗产的科学研究，公众教育；保护方法技术；与文化遗产的关系；与城市和区域发展规划的关系；与旅游产业发展的关系，地质公园与国家公园的关系；欧、美及非洲、大洋洲和亚洲各国地质公园发展前景等。

8Ps for native and NaBH〓 chemically modified reaction centers, and the transfer process from H〓 to the final electron acceptor Q〓 occurs in about hundreds of picoseconds. On the other hand, the energy transfer from excited B was obviously slowed down in the pheophytin-exchanged RC. By considering the change of free energy of ion pair P〓Phe〓, it could be expected there might exist alternative pathway of charge separation and electron transfer in pigment-exchanged reaction center. In addition, the influence of acid environment on the ultrafast dynamics of reaction center was also experimentally observed, which shows an evident difference from that of in native RC, and further investigation should be carried out to elucidate the origination.

在色素置换后的反应中心中，以B为起点的能量传递较天然RC的情况明显减慢，约在450fs左右，考虑到置换后的反应中心中P的自由能有所提高以及其仍然保持的光化学活性，这一较慢的能量传递也可能预示着还存在着其它的能量传递通道；另外，还对酸性处理的反应中心中的超快光动力学过程进行了尝试性的研究，发现由于色素分子的聚集以及蛋白环境的改变，BChl分子的激发态动力学过程有着明显不同于天然反应中心的情况。

When people talk about"the great living Buddha",the picture they have in mind is always like this;among a crowd of hundreds and thousands of people sitting high there on the grand rostum is the great Lama with stalwart body and a magnificent glowing of Dharma,rolling the rtamboling,chanting Sutras,surrounded by streamers,Image as such is the image of a "great living Buddha"

前言 十五世香根·拉马交活佛慈悲巧善巧教化众生的美名已响彻九洲。当有人问起活佛的情况时，聆听过他老慈语甘露的有缘弟子们，一般会告诉别人，上师是黄教有名的四大香根活佛之一。
