In recent years, with the development of various good catalysts especially the ruthenium alkylidenes bearing N-heterocyclic carbene ligands, the RCM reaction has been applied widely in the synthesis of complex organic molecules, biological molecules and natural products etc. The Nobel Prize in Chemistry 2005 goes to Yves Chauvin, Robert H.

近二，三十年来，随着各种性能优良的催化剂的不断发展，尤其是含氮杂环卡宾配体的钌催化剂的出现，关环复分解反应在合成复杂有机分子，生物活性大分子以及天然产物等方面已得到了极为广泛的应用。2005 年的诺贝尔化学奖分别授予了 Yves Chauvin，Robert H。

By using the group-chain, the wavefunctions of the 4f〓 configuration for RE ions are also expressed as linear combinations of group-chain basis functions in Butler's irreducible representation notation. The matrix elements of the CF Hamiltonian then are calculated by means of the Wigner-Eckart theorem and factorization lemma of the jm factors. Before the CF level fitting, a point-charge calculation of the conventional CF parameters B〓 has been performed by means of the lattice-sum technique from the known crystal structure data. The corresponding parameters in the group-chain are calculated by the conversion relationship between two schemes that proved identical in essence, which are usually used as initial values in the fit to the experimental levels. The ratios of the same k-value CF parameters are suggested as the constraint conditions in the fit, in order to utilize fully the symmetry distortion degree of the studied system.

利用群链理论，属稀土离子4f〓组态的波函数表示为以不可约表示标记的群链基波函数的线性组合；借助Wigner-Eckart定理和2jm和3jm因子的分解定律计算了晶场哈密顿的矩阵元；根据点电荷模型和已知晶体结构数据，利用点阵求和技术计算得到传统晶场参数B〓初值，相应的非传统形式的群链参数初值则由两种方案下的转换关系求得；这些初值通常作为非线性拟合晶场能级计算的初值，系统的对称性畸变信息则反映在以同阶晶场参数的比值作为能级拟合的约束条件。

Secondly, enrichment of 13C and 15N and their combination with NMR spectroscopy can help us study not only the dynamics of decomposition of organic materials but also the changes of their chemical structures during the turnover of the organic materials, which can provide more information in clarifying the C and N cycling and humification of the organic materials applied to soils.

本文根据已收集到的部分资料，对13C标记技术在土壤和植物营养中的应用情况作一简要综述，并在此基础上讨论了13C加富标记技术在研究植物光合作用、光合产物的去向以及标记秸杆在土壤中的分解等方面的应用及其注意点，旨在能为国内开展这方面的工作提供十分有用的参考

Wavelet multi-scale analysis is applied to the research on lunar gravity field and the explanation of lunar inner structure. In this paper, the nearside of the Moon with higher quality data is chosen as the test area, and free air gravity data from "Clementine" mission are used as original data to decompose gravity of some specific mare basins. With the results of numerical test, we also explain the hierarchical structure of the Moon, analyze the thickness of mare fillings and the Moho topography under mare basins, and verify the results by comparisons.

本文将小波多尺度分析引入月球重力场的研究，选取测量数据质量较好的月球近区作为实验区域，以"Clementine"探测器获得的自由空气重力异常作为原始数据对主要月海盆地进行了局部的重力异常分解，解释了月球内部基本分层结构，并利用主要月海盆地的实验结果分析了月海下部质量异常以及莫霍面的起伏形态，与已有研究成果进行比较证明了方法的适用性及结果的合理性。

Their thermal decomposition processes were proposed.Further, their photo-chemical reaction of films containing onium salt was investigated by IR and UV spectra.

聚合物的热分解过程已被提出，而由它们形成的包含有硫铺盐的薄膜的光化学反应过程也通过IR和UV进行了研究。

Efforts to develop engineered intestines are also proceeding, Dr. Vacanti said. Engineered esophagi, jejunums, and colons, grown on tubular degradable polymers, are showing angiogenesis and some neurogenesis. Motility is present although dysfunctional, Dr. Vacanti reported.

肠的制造也正在努力进行中，人工制造的食道、空肠及结肠，在管状的可生物分解聚合物上生长，已显示出血管及神经的发生，但是其蠕动性还未正常运作。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
