Reduced SQP based on orthonormal bases, orthogonal bases and coordinate bases are studied and compared. With the correction item introduced, the null-space move is adjusted and the reduced SQP based on coordinate bases decomposition is improved.●The key problem of steady-state data processing for RTOPT is studied. A new algorithm of simultaneous strategies for data reconciliation and gross error detection is proposed. Here the objective function that is constructed using maximum likelihood principle and joint distribution function is minimized. Efficient algorithm is developed which exploited the nonlinear lease-square structure of this objective function.

仿真结果表明了算法的有效性；●深入研究了在线优化中的一个关键问题——稳态数据处理问题，用基于组合概率分布的目标函数联立求解粗劣误差检测和数据调和问题；以精馏塔在线优化的数据处理和模型修正为例，提出一种根据模型方程对参数的依赖性进行过程模型分解的分层策略，可以将数据调和和参数估计统一在数据处理的大框架中，为进一步的过程性能分析、操作状况评价以及在线优化提供可靠的基准，具有非常重要的工程应用价值；●将优化命题的形式扩展到更通用的形式。

There have been caught in Walden pickerel, one weighing seven pounds —— to say nothing of another which carried off a reel with great velocity, which the fisherman safely set down at eight pounds because he did not see him —— perch and pouts, some of each weighing over two pounds, shiners, chivins or roach, a very few breams, and a couple of eels, one weighing four pounds —— I am thus particular because the weight of a fish is commonly its only title to fame, and these are the only eels I have heard of here;——also, I have a faint recollection of a little fish some five inches long, with silvery sides and a greenish back, somewhat dace-like in its character, which I mention here chiefly to link my facts to fable.

在瓦尔登湖中，捉到过梭鱼，有一条重七磅，且不去说那另外的一条，用非常的速度把一卷钓丝拉走了，渔夫因为没有看到它，估计它稳稳当当有八磅的重量，此外，还捉到过鲈鱼，鳘鱼，有些重两磅，还有银鱼，鳊鱼（学名Leueiscus Pulchellus），极少量的鲤鱼，两条鳗鱼，有一条有四磅重，——我对于鱼的重量写得这样详细，因为它们的价值一般是根据重量来决定的，至于鳗鱼，除了这两条我就没有听说过另外的，——此外，我还隐约记得一条五英寸长的小鱼，两侧是银色的，背脊却呈青色，性质上近于鲦鱼，我提起这条鱼，主要是为了把事实和寓言连接起来。
