This paper builtup esterification model, pre-polycondensation model, polycondensationmodel, and successfully built up monitoringon-line system of some key quality tar gets as well as operation systemmodel according to the polycondensation technique of NOY company.

本文在软测量技术的基础上，建立了酯化反应控制模型、预缩聚反应控制模型、终缩聚反应控制模型，并成功开发出在线控制系统，对生产过程中的关键质量指标如粘度、二甘醇、端羧基进行在线控制，控制精度达到小于2.5％。

The pyrometric cone and colored crayons and paints which indicate whether or not a certain temperature range has been exceeded serve a real need in certain high-temperature measurement situations, particularly where motion, as in tunnels and kilns, is involved.

B： Control Panel 背景知识：控制盘是控制系统与操作员之间的界面。常规的控制盘是一个钢的框架，上面装有各种显示仪表，控制仪表，报警装置和控制按钮。现在越来越多的控制系统的人机界面已经由计算机界面等取代。

The invention relates to a dynamic matrix control system of high-purity distillation, which comprises distillation tower, intelligent checker, DCS system, superior host, and on-site bus, while they are connected. The control system uses tower product group as the object variable, and the reflux ratio and reboil ratio as control variable; the superior receives history temperature and pressure data from the DCS real-time database, via the predict control and dynamic matrix controller, to obtain the output values of present controller as reflux ratio and reboil ratio, then feedback said two values to DCS system, to function the distillation object. The invention can confirm the high-purity stable operation, with better dynamical control.
