摘　　要：贮箱一般采用称重法进行容积测量,但测量值与理论设计值偏差较大。分析了贮箱在生产制造、液压试验、介质加注、称重、容积计算和变形等环节出现偏差的原因。通过贮箱计算实例分析了各环节偏差大小,提出了减小偏差的对策,并对贮箱容积测量提出了改进方案。The weighting method is usually adopted to measure the volume of tanks, but its measured value has a great deviation from the theoretical value. The reasons that the deviation occurs in the process of manufacture, hydraulics test, medium filling, weighting, volume calculation and distortion are analyzed. The deviation value of each link is also analyzed by means of an example of tank volume calculation. Some solutions for decreasing the deviation and a modification scheme regarding with tank volume measurement are proposed in this paper.
