The effect of lead treatment on the soil microbial biomass carbon, microbial biomass nitrogen, micro-bial activities, rice physiological indices and rice biomass in the interactive system of soil-rice-lead and microbe, were studied by a greenhouse pot experiment. Lead was applied at six different levels in two different paddy soils, namely 0, 100, 300, 500, 700 and 900 mgkg^(-1) soil.

盆栽试验研究了土壤－水稻－铅－微生物相互作用的体系中，外源铅不同处理水平CK、100、300、500、700、900mgkg^(-1对两种水稻土壤微生物生物量碳、氮，微生物活性，水稻生理指标及生物量的影响。

Mol/L for 5days after adaptation to cadmium exposure at varied concentrations, it was found that accumulations of lead increased a little after pre-exposure to cadmium for 5days.

可见驯化暴露镉诱导了鳃和肾中金属硫蛋白的合成并在其后的铅暴露中增加了铅蓄积。

Super large type sedimentary hydrothermal sulfide ore deposits, located in middle Qinling and west Yinshan mountains, has shown the multi metal and pyrite type deposit The deposits are shown sililay geo geochemistry characteristics to SEDEX sulfide deposits in middle Proterozoic and Paleeozoic Era in the world, i e , ore forming age were 1 4～1 2 Ga and 0 4～0 3 Ga ore bodies show more than 1 000 m long and multi layered distribution, the ore of sulfide rich show massive band...
