摘　　要：针对储罐在安装过程中和长期使用后会由于地势、温度、压力发生倾斜、膨胀、蠕变等变形，而这些变形造成容积表难以确定，应用三次平滑样条处理数据的方法以及对称映射算法，提出了一种卧式储罐标定数据分析与容积表生成的方法，并建立卧式储罐标定数据分析与容积表生成系统，通过实例分析和比较验证了该方法的可行性。现场应用情况表明，该方法处理卧式储罐标定数据是有效的。The method of calibration data analysis and volume table generation for a horizontal storage tank are presented, which is based on cubic smoothing spline and symmetric mapping algorithm. It is used to solve the problem such as incline, expansion and creep caused by topography, temperature, pressure. The problem will cause the uncertainty of capacity. At the same time, a system about the calibration data analysis of horizontal storage tank and the volume table is established. The feasibility of this method is verified by case analysis and comparison. The field-application shows that it is valid to process calibration date of the horizontal storage tank.
