On the one hand, the charge transfer between the complexes and the valence band is very fast, but the liberation of iodine, I〓, may be rather slow due to the interaction and/or the formation of complexes between donating electron species and the accessible Fe sites at the surface. Therefore, minority carriers (photo-induced holes) tend to accumulate in the FeS〓/electrolyte interface causing the flatband potential shift towards positive energy and the decrease of the maximum theoretical photovoltage. On the other hand, the occurrence of unoccupied surface states in the forbidden zone due to the strong chemical interaction of iodine with FeS〓 surface leads to the increase of both surface recombination dark current and tunneling dark current causing the decrease of open circuit photovoltage. The self-assembled monolayer of n-octadecylamine.
FeS〓/电解质界面化学行为理论模拟与太阳电池开路电压的理论分析表明：碘离子I〓与FeS〓（100）表面产生强烈化学吸附作用，H〓O分子与FeS〓（100）为物理吸附，因此I〓/I〓电解质可以强烈抑制FeS〓电极光腐蚀；同时，与弱相互作用体系相比，强相互作用体系的界面电子传递隧道距离缩短而使光电流增加，提高了量子效率；I〓分子吸附一方面阻碍了溶液中的I〓在FeS〓电极表面的吸附，导致光生空穴在表面发生积累，最终的结果是FeS〓电极平带电势ψ〓正向漂移，致使理论最大光电压降低，另一方面，由于I〓吸附导致带隙处未占表面态增多，表面复合电流与隧道电流明显增大，从而使光开路电压U〓降低。

Preliminary results show that fossil mammal communities in North China are rather stable and uniform from the end of Middle Miocene till the latest Miocene (ca. 13 Ma to 7 ～ 8 Ma). The differentiation of a humid and closed fauna in the east, a dry and open fauna in the west during the latest Miocene might be closely related with intensification of the East Asian summer monsoon. Fossil mammal dispersal evidences from Tibet and adjacent areas suggest the formation of a geologic barrier due to uplift of the Tibet Plateau that might also be the cause of intensification of the East Asian summer monsoon. The Pliocene faunas from North China show strong adaptation to open and dry environments. The diversification and dominance of some lineages, such as siphneids and ochotonids, may well be explained by the climatic vibration during the late Pliocene.
结果表明，自中中新世晚期至晚中新世(约13 Ma至7～8 Ma)，中国北方哺乳动物群落组成上没有明显的分异；而在其后的晚中新世晚期发生了较为明显的区域性分化，分化为东部地区以适应潮湿的较为封闭的动物群落与西部地区适应干旱的开阔环境的群落，这种分异可能与东亚夏季风的加强密切相关；青藏高原及其周边地区化石类群的扩散与交流资料也表明由青藏高原隆升而形成的地理阻隔也可能发生在该时期；上新世哺乳动物群落演化表现出对于持续的干旱化气候背景的适应，而晚上新世某些类群的分异与主导地位的确立与该时期气候环境背景的剧烈震荡相一致。

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。
