Distortionless Lossy Transmission Lines Terminated by in Series Connected <i>RCL</i>-Loads

The paper deals with a lossy transmission line terminated at both ends by non-linear RCL elements. The mixed problem for the hyperbolic system, describing the transmission line, to an initial value problem for a neutral equation is reduced. Sufficient conditions for the existence and uniqueness of periodic regimes are formulated. The proof is based on the finding out of suitable operator whose fixed point is a periodic solution of the neutral equation. The method has a good rate of convergence of the successive approximations even for high frequencies.

宝钢1550冷轧精整卷线产能影响因素分析

影响生产机组产能因素很多,定量分析各因素对机组产能的影响,对机组产能的提高及产能平衡有着非常重要的意义。通过统计分析了出口卷重、钢卷厚度、宽度、分选度、拉矫、剪边及生产品种对宝钢分公司1550冷轧精整卷线产能的影响。分析结果表明,以上因素对产能的影响程度依次为：分选度、带钢宽度、厚度、出口卷重、拉矫、剪边,其中宽度对小时产量的影响较复杂呈二次抛物线关系。可通过优化与上游机组之间的生产组织和相互平衡两条机组之间生产品种的分工,提高机组产能。
