Five of their single crystals were obtained and their structures were determined by X-ray diffraction. By comparison, it was found that dithiocabamate complexes often formed an exactly planar MS4 unit, such as [Mo(R2dtc)2]; and also formed a special MS 5 unit, such as [Cu2(R2dtc)4], the copper atom lies in a distorted square-pyramidal environment.Four kinds of heteropoly acids were prepared and characterized; a series of solid superacid catalyst of supported heteropoly acid were prepared and characterized; regioselectivites of chlorobenzene mononitration with nitric acid with different heteropoly acid on different supports and reaction conditions have been investigated.

培养并解析了5个该类配合物的单晶结构，通过比较，发现二硫代氨基甲酸盐与过渡金属容易形成四配位结构，金属原子与4个硫原子共平面，比如二乙基二硫代氨基甲酸钼；也能形成比较特殊的五配位结构，比如二乙基二硫代氨基甲酸双核铜，Cu原子与5个S原子相连，处于一个变形的四方锥结构的配位环境。

Differential scanning calorimetry and polarizing microscope were used to study their liquid properties. Among them, nine are found to exhibit liquid crystal properties, and most of them displayed as heating monotropic liquid crystals. There are one or two mesophases and certain phase transition temperature,Δ H and temperature range of liquid crystal.

用差示扫描量热仪和偏光显微镜研究了其液晶性，发现其中九个配合物具有液晶性，多为升温单变液晶，有一至两个中介相，有确定的相转变温度、热焓和相变区间。

The results show that the bittervine can absorb and metabolize a large quantity of glyphosate. If the glyphosate metabolite AMPA in the plant is used as an index, then the moraceae has the best metabolic effectiveness. The next effective is the bidens pliosa; the worst, the bittervine.

由研究成果显示优势植物小花漫泽能吸收及代谢大的嘉磷，但如果以植物体内嘉磷代谢物AMPA为指标观察，则发现葎草有较好的代谢成效，其次为咸丰草，最差的是小花漫泽。

Cubic particles with average size of 5μm are found and the ratio of PbTiO3/PbZrO3 in PZT is about 53/47, which is around morphotropic phase boundary; Density is figured out through the datum measured in experiments.

发现PZT薄膜由平均尺寸约为5μm的PZT晶粒组成，其物相组成成分PbTiO3和PbZrO3的比值约为53/47，处在准同型相界附近。

More and more chemists pay attention to study the influence of metal ions, multidendate ligands, synthetic routes and synthetic condition on the formation and the structural characterization of multinuclear compounds.

人们已经发现，在某些情况下多啮Shift碱配体可以与过渡金属形成结构类型各异的多核配合物。

Recently, it has been found that the multinucleate complexes play an important role in organism due to their unique catalysis and biological activity.

近年来，人们发现多核配合物在生物体内具有独特的生物活性和催化作用。

Using the primers from SRY gene-HMG Box for PCR amplification in genomic DNA of Muntiacus reevesi cell strains, a 220bp fragment was obtained in the male but not in the female.

应用人的性别决定基因SRY (Sex-determining Region Y gene， SPY)中HMG框内的一对引物，对小麂细胞株的基因组DNA进行PCR扩增，得到雄性小麂细胞的220bp扩增产物，而在雌性小麂细胞中未发现扩增产物。

The microstructures, phase compositions, magnetic properties of Sm2F17-type alloys and their nitrides have been studied by means of arc-melting, HDDR and nitrogenation processes.

通过采用电弧炉冶炼、HDDR及氮化的方法，对Sm2Fe17型合金及其氮化物的组织形貌、物相及磁性能进行研究发现，多补偿添加25%钐可使Sm2Fe17型合金退火后的α-Fe含量小于2%。

The process of happiness is, firstly a sincerity heart is needed, getting ride of desire and being void and quiet; secondly to touch something nonego, and some feeling rising, at the same time the imaging activity must evoked enough; thirdly more image is needed, in order to find a world of significance, then to obtain a experience of the mysterious ultimate existence, which is the end of the aesthetic happiness with a mental mode named"wandering".

乐的过程，首先是要使其心诚，去欲而虚静；其次是要对外物有所感，并能兴发起一定的情感，与此同时想象活动要充分展开；再次，要进一步展开想象，发现一个意义世界，并由此获得对神秘的终极存在的体验，这才是以&游&的心意状态表现出的审美之乐的极至。

It achieves a certain extent effect of waterproof and oilproof. 3. Test the change of surface ingredient before and after the fluoridized of the FRP usingthe reflecting method of infrared spectrum. Then dip the fluoridized FRP in the cold water, warm water and petroleum ether for about half an hour, and surface ingredient havent changed too much.

用红外光谱反射法测试了经含氟物处理前后的玻璃钢表面结构变化，并且分别测试了在冷水、温水、石油醚中浸泡洗涤半个小时后的表面含氟处理的玻璃钢的表面结构，发现其表面结构与浸泡前无大的变化。
