The lifetime of M intermediate of the three mutants in PVA films were recorded by employing photomicrography. In distilled water, the visible absorption maximum of BRI119T/T121S/A126T and BRI119T/T121S/A126T/E194Q mutants were blue shifted notably by 11 and 12 nm respectively and the BRE194Q's was weakly red shifted in comparison with WT-BR.

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.

本项目立足于从火山岩属性和深源捕掳体反演源区成分与结构两个途径，利用火山岩综合研究成果对地幔源区进行了初步反演，提出源区经受过强烈钾质交代的观点；对重点工作区TM图像进行了初步解译，新发现若干了火山口，并对其中三个火山口作了实地查验，为进一步全面深入开展该区的火山地质学及相关科学问题打下了良好基础，认为托云盆地是一个火山群，而不是一个单一的火山构造盆地；系统测制了火山岩剖面，新采集了一批重要的火山岩和深源岩石捕虏体样品，为下一步工作打下基础，特别是采集到了直径打20cm的幔源橄榄岩包体，可用于各种测试，将可以结束西部造山带没有地幔岩化学分析结果的历史；对康西瓦玄武岩进行了测年分析，取得了我国目前最年轻的锆石U-Pb SHRIMP年龄，对青藏高原挽近地质时期的隆升提供了年代学约束；对帕米尔东缘塔什库尔干碱性岩体的动力学意义进行了探讨，提出青藏高原西部构造结的形成与岩浆活动有关的观点。

In order to prove the importance of three-body interaction, accurate ArH〓 potential surface and accurate ArAr potential surface are added to construct a two-body potential surface. We found that this potential surface is corresponding with a deep potential well and a tight structure, which is far from the real structure of Ar〓H〓. Obviously, this two-body additive potential surface is not suit in this system.

为了证明三体作用在体系中的重要性，我们用精确的ArH〓的势能面与精确的ArAr的势能面构造了一个两体加和的势能面，发现两体加和的势能面表现的是一个深势阱的紧凑结构，与Ar〓H〓的结构相去甚远，因此可以确认，两体加和在此系统中是不适用的。

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.

通过研究，我们提出了初步的NodD操纵子激活模型：第一，四聚体是NodD蛋白的功能单位，它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子；第二，小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体，在我们的模型中，NodD四聚体缩小其V形主体的弯折角，进而缩短其DNA结合功能域的间距；第三，小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用，NodD的构象改变由蛋白质经其双铆钉位点传递给DNA；第四，只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物；第五，不排除NodD与RNA聚合酶可能有直接的相互接触位点，不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物，但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。

The carboxyl of the tripodal ligand is a goodbridging group. The building blocks are linked together by the bridging group andother weak interactions (hydrogen bond and π-π stacking interaction, etc), thusgenerating a one, two or three-dimensional metal complexes.2. Studies on the fluorescence properties of the lanthanide complexes indicated that:(1) The excitations in the ligand-based π-π〓 transitions cause the structuredemission of lanthanide complexes while the ligand luminescence is completelyquenched showing that ligand-to-metal energy transfer occurs.

三脚架配体所带的羧基是一个很好的桥联基团，配合物的结构基元通过这种基团的桥联作用及其它一些弱的作用力(如氢键、π-π堆积作用等)联系起来，构成了一维、二维或三维的超分子空间结构。2、稀土配合物的发光研究发现：(1)用配体的π-π〓跃迁波长进行激发，配合物均显示出稀土离子的特征发射峰，同时，配体的荧光峰没有出现，这说明在三脚架配体与稀土离子间进行了有效的能量传递。
