Cl-、NO3-和SO42-离子对漆酶催化活性的抑制作用

以５,６－二溴－２,３－二氰基氢醌为底物,在ｐＨ值４．５０条件下,用分光光度法考察了Ｃｌ－、ＮＯ－３和ＳＯ２－４离子对漆酶催化活性的影响。发现Ｃｌ－、ＮＯ－３和ＳＯ２－４离子对漆酶的催化活性均有不同程度的抑制作用,其最大抑制率分别可达７５％、３１．４％和１７．１％。动力学研究表明,Ｃｌ－、ＮＯ－３和ＳＯ２－４离子的抑制作用是瞬时完成的,属于竞争性抑制过程,是通过与底物分子竞争漆酶分子中的Ⅱ型铜（Ⅱ）部位实现的。经测定,Ｃｌ－和ＮＯ－３离子与漆酶所形成的复合物其解离常数分别为１．１２×１０－４ｍｏｌ·ｄｍ－３和１．７８×１０－３ｍｏｌ·ｄｍ－３。     

Genomic organization of EDSV strain AA-2

The genomic organization of egg drop syndrome virus strain AA-2 isolated in China is reported here. The genome was found to be 32 838 bp in length, approximately 2 kb shorter than those of the human subgenus C adenoviruses. Analysis of open reading frames indicated that the genes for major viral structural proteins (55 K, Penton base, pⅦ, pⅩ, pⅥ, Hexon, 100 K, pⅧ and Fiber), as well as EP, DNA polymerase and ⅣaⅡ are present in the expected locations in the genome. EDSV possesses no identifiable E3 and E4 regions and most proteins encoded by E3 and E4 regions of other adenoviruses genome were not presented in EDSV.     

Diamond synthesis from a system of chromium-carbide and Ni70Mn25Co5 alloy

In order to ascertain the mechanism of interaction between carbide and metallic catalyst and formation of diamond under high pressure and high temperature, and find a new method to synthesize diamond with special properties, it is necessary to investigate the reaction behavior of different carbides and metallic solvent_catalysts under high pressure and high temperature. A system of Cr-3C-2 powder and Ni 70Mn 25Co 5 alloy in weight ratio of 1∶6 was treated under 6 0 GPa and 1 500℃ for 20, 30 or 60 min respectively. X_ray diffraction of the samples indicated the Cr 3C 2 decomposed partially after high pressure and temperature treatment, and Cr 7C 3, Cr and diamond formed respectively. There was not any trace of graphite in the samples. The result suggested that the separated carbon atoms could form diamond directly without conversion process of graphite into diamond. The observation of SEI, WDX and EDX also showed that diamond crystals were synthesized in the system, which have perfect surfaces and shapes, with the average grain size of about 40 μm. The properties of the crystals are being investigated.

热稳定剂对PVC／PU共混体系性能的影响

本文研究了ＰＶＣ的热稳定剂对ＰＶＣ／ＰＵ共混体系性能的影响．通过红外光谱、热分析和透射电镜等手段探讨造成共混物性能差别的原因．结果表明：金属皂类稳定剂最有利于共混体系的韧性改善,而有机锡化合物、铅盐均不利于提高共混物的缺口冲击强度．不同的稳定剂对共混体系的应力－应变行为影响不大．溶剂抽提和红外光谱结果表明,加工过程中可能导致的化学交联不起显著的作用．动态力学的结果表明,不同的稳定剂体系导致ＰＵ与ＰＶＣ的两相相容性有差别,从而导致共混体系相态结构的差异,透射电镜研究结果证实了这一点．
