该矿区土壤微生物区系组成和微生物活性显著不同于临近非矿区土壤，随着重金属含量的增加，土壤微生物数量、微生物多样性指数、微生物生物量碳以及纤维素分解强度均显著降低，但土壤基础呼吸却明显升高；土壤脲酶、碱性磷酸酶、多酚氧化酶对铅锌矿较为敏感，而蔗糖酶和过氧化氢酶受到的抑制作用不明显。

Results of non-reducing sodium dodecyl sulphate polyacrylamide gel electrophoresis of the supernatant and aggregate precipitate formed in refolding process show that except being refolded to native egg white lysozymes, the reduced-denatured lysozymes can also form the aggregates with molecular weights being separately about 30.0 and 35.0 kD, while the reducing SDS-PAGE and the refolding results in the presence of sodium dodecyl sulphate show that these aggregates are formed chiefly through the misconnection of disulfide bonds between the reduced-denatured lysozymes, and the aggregate precipitates are formed through the non-covalent interactions between the aggregates with molecular weight being about 30.0 kD.

复性过程形成的上清和集聚体沉淀的非还原电泳结果表明，除了能复性成天然态的溶菌酶分子外，还原变性蛋白溶菌酶同时还能形成分子量分别约为30.0KD和35.0KD的蛋白溶菌酶分子集聚体；而它们的还原电泳和在SDS存在时的复性结果表明，这些集聚体主要是通过还原变性蛋白溶菌酶分子间的二硫键错配而形成，而集聚体沉淀则是通过分子量约为30.0KD的集聚体分子之间的非共价相互作用而形成。

The nuclear protein encoded by N gene is consist of 422 AA residues (47kDa), Each virion contains 1258 copies that can effectively protect viral RNA from being digested by nucleotidase. The N protein presents a group specificity, it exists in various types and subtypes of VS and plays a very important role in transcript copy. Due to its characteristics of high antigenicity, the N protein can stimulate the body producing nonneutralized antibody.
