采用X射线荧光、X射线衍射、热膨胀等分析手段对比研究了安阳商代陶水管的制作工艺，发现陶水管化学成分中各类熔剂的质量分数均略高于对比陶片中熔剂的质量分数，CaO、K2O、MgO等助熔剂与A l2O3的质量比进一步证实该现象，而这种差异性则外在地表现为陶水管的气孔度低于对比陶片以及陶水管热膨胀曲线中出现玻璃化现象，该结果表明陶水管原料应为一种易熔粘土，或者在沉淀粘土中人为地掺和了草木灰类掺和料，这有利于陶水管烧制与成型，有助于熔剂在熔融状态下，较好地进入陶水管中的空隙，使陶水管变得更加致密，一定程度上有利于防止陶水管的渗水，显示出陶水管制作工艺的特殊性。

In this method, first, the gray-scale image of the molten pool is obtained according to the fractal-based discrete Brown random field theory. Next, the connected domain is detected based on the binary morphology theory and is then used to remove the noise and obtain the target image. Moreover, the successive edges of the image are obtained by means of the Open-Close operation on the basis of the mathematical morphology theory.

The results indicate that the interface curve in width varies along the flow direction. The flow rate ratio controls the coextrusion interface location. The interface deviate value increases with the increasing of the flow rate ratio. The difference viscosity of two layers polymer leads to the interface deflecting towards the lower viscosity side.

结果表明：宽度方向共挤出界面的形状和位置沿聚合物流动的方向不断变化；界面偏移量的大小随着流量差异的增加而增大；聚合物入口流量的变化是导致共挤出界面位置变化的决定性因素，流量比的变化对出口处界面形状的影响不大；两种聚合物粘度的不同会导致界面偏向粘度较低的熔体一侧。
