摘　　要：讨论储油罐的变位识别及变位后罐容表的标定。为得出油罐变位后的液体容量,利用微积分的思想建立积分模型、并用实验数据建立插值模型,给出了完整的罐容表标定值,且通过误差分析,验证标定值的正确性。对于实际储油罐的实测数据,利用分层搜索法确定变位参数,并进行灵敏度分析,得出了纵向倾斜的灵敏度远大于横向偏转的结论。The paper discusses displacements recognition and calibration of the tank capacity charts.In order to get the data of liquid capacity after displacements,the paper establishes integral model with calculus sets up the interpolation model with experimental data and confirms the exactness of calibration with error analysis.The paper determines displacements parameters with hierarchical search method and concludes that sensibility of the vertical tilt is much more than horizontal deflection with sensitivity analysis.
