Yield point is determined by extrapolation from the flow curve.

屈服点可以通过流变曲线外推法而得到。

Based on a study of the influencing factors to ports throughputs, this paper analyzes the relationship between the factors and the throughputs, used the linear regression prediction models to forecast the throughput of nationwide, so the coastal ports can be achieved, then based on the relations of the whole and the part, we can got the throughput of Tianjin, Dalian and Qingdao port; in addition, this text choused to use three models of trend extrapolation model , and made the detailed introduction to these three model"s principles, e.g. the Logistic growth curve Model, grey system model and exponential smoothing model to Predict the Tianjin, Dalian and Qingdao ports" throughput, compared these results, got three ports throughput in 2007 and 2010 years.

并在此基础上，通过整体与局部的关系，再预测环渤海港口群中的天津、大连和青岛港的货物及集装箱吞吐量；另外，本文还选用了趋势外推法中的三个预测模型，并对这三个模型原理作了详细的介绍，然后引用&逻辑斯谛生长函数&模型预测了天津、大连和青岛港集装箱吞吐量；用指数平滑和灰色系统模型预测这三港的货物及集装箱吞吐量；最后，通过分析比较这些模型的预测结果，得出三港在2007和2010年货物及集装箱吞吐量预测结果。
