基于传统的阶梯式均匀传输线逼近模型，对非均匀传输线进行分段指数逼近。
Based on the conventional ladder model, the exponential model is adopted to approach the nonuniform transmission lines.
对于非均匀磨损，其剩余抗拉强度与磨损长度之间的关系均近似服从指数分布。
The residual intensities both the uniform wear and non-uniform wear of casings have the reverse proportions with the abrasion depth on casings.
