摘　　要：The open loop dynamic behaviors of internal thermally coupled distillation column with four different purities （low., moderate-, high- and very high-purity） are studied. These dynamic behaviors are characterized by strong asymmetric non-linearity, high sensitivity to operation conditions change and distinct inverse response, With the increase of purity, these dynamic behaviors are intensified and become more complex, which easily lead to the mismatch between linear model and plant and also change the relationship between manipulated and controlled variables.开的环有四不同纯净的内部热地联合的蒸馏列的动态行为(低中等、高、很高纯净) 被学习。这些动态行为被强壮的不对称的非线性，到条件改变的操作的高 senstivity 和不同反的反应描绘。随纯净的增加，这些动态行为被加强并且变得更复杂，它容易导致在线性模型和植物之间的失配并且也改变在操作并且控制的变量之间的关系。
