天然气管线内腐蚀速度的逐步回归预测

Analysis of Regression and Prediction of Internal Corrosion of Natural Gas Pipeline

为了更深入地探索天然气管线中所输介质与内腐蚀之间的关系，利用实验获得的在气相或液相中Ｈ２Ｓ、ＣＯ２、缓蚀剂浓度与其所导致的内腐蚀速度值，采用数理统计的方法，确定Ｈ２Ｓ、ＣＯ２、缓蚀剂与内腐蚀速度之间的最佳的逐步回归方程，以达到预测内腐蚀速度的目的。

In order to investigate in depth relationship between pipeline medium and internal corrosion in gas pipeline and to predict internal corrosion speed,H 2S content,CO 2 content and inhibitor concentration in gas or liquid phase obtained in laboratory and mathematical statistics are used for determining optimal stepwise regression equation between H 2S,CO 2,inhibitor and internal corrosion speed.All stepwise regression processes and predictions are completed by compiled program system.
