The results show that the variation of diameter of ATF yarn increases with increasing the over feed of peel filament, but the variation of average diameter decreases. When the polyester FDY is used as core filament, the structure of diacetate composite ATF is looser than the ATF with capron as core filament, and the unevenness of yarn core and outside are also greater. The ATF loops or hairiness mainly centre at the height 0.5 and 1.0 mm, the amount decreasing with the height increasing, with exponential distribution. When the over feed of peel filament enhances, the number of loops or hairiness decreases at the height of 0.5 mm, while other height of loops or hairiness increases.

结果显示：空变丝纱芯直径的变异随皮丝超喂提高而增加，但平均直径的变异却呈下降趋势；以涤纶FDY做芯丝时，二醋酯长丝复合空变丝的结构较芯丝为锦纶的空变丝松散，纱芯和外围不匀程度也相对较大；空变丝丝圈丝弧或毛羽主要集中在高度为0.5mm和1.0mm的位置，其个数随高度的增加而不断减少，基本呈指数分布；皮丝超喂提高时，0.5mm高度的丝圈丝弧或毛羽个数减少，其他高度的丝圈丝弧或毛羽个数则增加。

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。
