Based on an analysis of dynamic conditions for migration and precipitation of gold grains in water system and their diffusion in soil, this paper has advanced a discriminant formula for surfacce ore potential of gold anomalies from 1 : 50000 stream sediment survey, recounted methods for estimating the highest gold grade ores within the anomalies, calculated the discriminant indices for qinba area, and summed up index characteristics of ore - induced gold anomalies in 1 : 10000 soil survey, estimation formulae for orebody location as well as coefficients and constants of slope angles of various orders and grades
摘要在分析金粒在水系中運移、落淤和在土壤中擴散動力條件的基礎上，本文建立了五萬分之一水系沉積物測量金異常地表含礦性的判別公式，闡述了推算異常內礦石最高金品位的方法並計算了秦巴地區的判別指數；總結出萬分之一土壤測量礦致金異常的標志特徵、礦體定位的估算公式及各級次地形坡度角的系數和常數。 -
The dissipation rate constants of malathion and methyl parathion with a concentration of 3 mg / l, and ethion, dicofol, and cyhalothrin with a concentration of 0. 5 mg / l in 2000 ml of 55 - 60 g canna planted water sulution were respectively increased by 77. 66 %, 117. 44 %, 64. 80 %, 38. 11 %, and 15. 35 % compared to those in unplanted water solutions
62mg幾。在植物修復過程中，鳳眼蓮的直接吸收積累與降解起主要作用，而微生物降解的作用除對樂果的凈化與植物吸收積累的作用相當外，對其他農藥則相對較小。與不種植植物的對照相比， 50乃0g美人蕉對2000ml分別含有3mg幾的馬拉硫磷、甲基對硫磷及0
