However the addition order of tartrate and phosphate on activity of enzyme adsorbed by goethite produced the greatest impact.

胶体表面类型（硅氧烷表面或羟基化表面）及阴离子配体对胶体表面负电荷的贡献量在酶的吸附及活性保持中的重要性；B阴离子配体后加入时酶的吸附量一般比配体先加入时的高；C）配体加入顺序对二氧化锰的影响最显著，对砖红壤和高岭石的居中；对针铁矿的次之；对黄棕壤的最小。D）乙酸或草酸加入顺序对高岭石上固定化酶比活性的影响最大，而酒石酸或磷酸则对针铁矿影响最大。

Polyhedrin and virion, which were isolated and purified from Agrotis setegum nuclear polyhedrosis virus, are administered to 3-instar Heliothis armigera larvae with Heliothis armigera nuclear polyhedrosis virus. Both polyhedrin and virion could increase mortality of H. armigera larvae, shorten half mortality time and decrease half mortality concentration.

对黄地老虎核型多角体病毒的多角体蛋白和病毒粒子组分进行分离纯化，分别与棉铃虫核型多角体病毒混合感染三龄棉铃虫幼虫，发现此二种组分均能够提高棉铃虫幼虫的死亡率，缩短半致死时间，降低半致死浓度。

Results Eight species belonged to three families, two orders of rodent animals and seven species of fleas were found in this area. Rattus losea and Xenopsylla cheopis were dominant species, R.flavipectus , R.norvegicus , Suncus murinus , and Banolicota indica were familiar species.
