摘　　要：经对比实验，分析在饮用水放射性活度测定中，同一水样以不同蒸发浓缩方式制得不同残渣量的原因，得出控制水温及蒸制体积是制取准确残渣量的前提，从而在水样蒸发浓缩环节减少对放射性活度测定结果准确度的影响。With control ,the reason for different residue quantities of the same sample disposed by different evaporating and concentrating methods in determination the radioactivity of drinking water was discerned. Based on it, it can be concluded that controlling water temperature and evaporating volume of water are preconditions for precisely obtaining residue quantity in order to reduce the influence on accuracy of the result in determining the radioactivity of water sample in the course of evaporation and concentration.
