The ascendancy community was Calliphoridae. Herbivore\'s ascendancy communities were Oides decempunctata, predator\'s were Erigonidium graminicola Sundeall, parasite\'s and neutrality\'s were Calliphoridae.3、The seasonal dynamics overall change of community\'s individual numbers, species, relative abundance were basically consistent. All of them conformed to the wavy development trend of increasing -descending-suden increasing-descending-increasing.

By the testing means of electron-spectroscopy for chemical analysis , thermogravimetric analysis , differential scanning calorimetry , transmission electronmicroscopy , the results have shown that the emulsion polymerization in situ in the presence of nano-particle of calcium carbonate can happen smoothly and successfully and the surface of nano-particle of calcium carbonate have been capsulated by polymer of acrylates, which prevent from the agglomerating of nano-particles of calcium carbonate. Because the copolymer of acrylate has good compatibility with some plastics such as PVC, ABS, AS and so on, so the dispersion of nano-scale calcium carbonate as nanometer size in these plastics can be reached more easily and the effects of nanometer can happen.
通过X射线光电子能谱、热失重分析、动态扫描量热分析、透射电子显微镜等手段,证实在纳米碳酸钙原生粒子存在下,可以进行丙烯酸酯类的原位乳液聚合,乳液聚合顺利,纳米碳酸钙表面被丙烯酸酯类聚合物所包覆,使纳米碳酸钙粒子间的团聚不易发生,同时由于丙烯酸酯类聚合物与PVC、ABS、AS等极性聚合物具有较好的相容性,从而使纳米碳酸钙在聚合物基体中能达到纳米状态分散,从而发挥纳米效应。

With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.
