Copper was reduced from 20 mg/l to below detectable limits by sulfide precipitation from a gold-ore extraction wastewater . 用硫化物沉淀法可將金礦抽提廢水中的銅含量從20毫克升降到可檢測標準以下。
Analysis of effect of the movement of nuclear material on the minimum detectable limit of the radiation detector array using mc method 方法計算分析核材料移動對輻射探測器陣列探測下限的影響
The minimum detectable limit of the nuclear radiation detector array is an important technic criteria to judge whether the detector satisfies the detecting requirements or not 摘要核輻射探測器陣列的探測下限是判斷其是否符合探測要求的重要技術(shù)指標。
The detection of moving nuclear material is more difficult than that of static one ( namely , the minimum detectable limit of moving nuclear material is lower than that of static one ) 從定性的角度易知,由于核材料移動時比靜止時的探測下限低而更難以探測。
This study adopts the monte - carlo general software - mcnp to compute and analyze the effect of movement of the nuclear matter on the minimum detectable limit of the nuclear radiation detector array 文章通過建立蒙特卡羅模型并應用通用軟件mcnp程序分析計算核材料的移動對核輻射探測器陣列探測下限的影響。
