锅炉烟气净化系统运行调优的意义和方法

实测表明，多数锅炉烟气净化装置和系统不是在最优化条件下运行。这是造成我国大气污染严重，已建烟气净化设施不能充分发挥效益的重要原因之一。本文在概略介绍系统调优及在其它行业取得的显著成果之后，重点介绍了锅炉烟气净化系统进行系统调优的意义和应创造的条件，以及系统调优的一般方法。     

医用流体射流技术的开发及应用

近年来，国内外的流体射流专业人员与外科医师密切合作，共同在医用流体射流技术领域为努力开拓。本文从下述几个方面扼要地叙述已经取得的成果、存在的问题及后续的开发研究工作：（１）流体射流对人体（即生物材料）的冲击效应；（２）脉冲水射流粉碎人体结石（主要有ＥＳＷＬ及ＥＰＷＬ）；（３）水射流对于良性脑膜瘤的剥离术；（４）无针注射及针刺疗法；（５）医用水射流手术刀；（６）医用水射流清洗机（即ＷＩＤ）。本文的第一节内容是开发医疗器械的基础研究工作，这方面的数据主要来源于对射流工伤病例的分析和概括。射流工伤已使人们付出高昂的代价！因此，流体射流工艺装备，包括医用器械的技术安全始终是首位。唯其如此，才能确保此项技术走向更加辉煌的明天。     

RESERVOIR MANAGEMENT RULES DERWED WITH THE AID OF MULTIPLE OBJECTIVE DECISION MAKING TECHNIQUES1

ABSTRACT: The determination of optimum reservoir operating rules for reservoirs with multiple conflicting objectives is still a difficult task - despite many publications in this field. In this paper a three-step Multi Objective Decision Making (MODM) method is presented, the emphasis of which is placed on the necessity to make the work easy for the decision maker, which many MODM techniques fail to achieve. The method is applied to the development of a compromise optimum operating rule for a multi-purpose reservoir. In the first step of the method stochastic DP is chosen which is combined with the “weighting method” allowing combination of various objectives into one objective function. By systematically varying the weights for the objectives a large number of pareto optimum reservoir operating rules is generated. In the second step of the method the performance of all these operating rules is tested with the aid of a model simulating reservoir operation. The results are statistically analyzed and the reliabilities for attaining the various objectives are computed. The third step of the model applies another MODM technique which allows the decision maker - in a computer dialog - to select his optimum reservoir operating rule from the large number of pareto optimum solutions generated in step 1. Here he can specify his preferences for the various objectives. For this purpose two alternative MODM techniques are offered: Compromise Programming and the SEMOPS method. Their performance is shown along with the generation and selection of operating rules for the multi-objective Wupper reservoir system in Germany.

低温对处理低浓度废水的厌氧折流板反应器性能的影响

采用一个9．9L的厌氧折流板反应器处理低浓度废水（COD500mg／L左右）,研究了低温对反应器运行性能的影响。结果表明,温度从35℃下降至20℃对ABR的处理效率没有明显的影响,COD去除率仅下降了3％。各隔室的VFA均上升,前面隔室中上升幅度更大。当温度从20℃下降至15℃时,产氢产乙酸菌和产甲烷菌等受到较大影响,在13d的时间内COD去除率下降了近一半,降至40％～60％。

APPLICATION OF GREY MODEL TOWARD RUNOFF FORECASTING1

ABSTRACT: A reliable forecasting model is essential in real‐time flood forecasting for reducing natural damage. Efforts to develop a real‐time forecasting model over the past two decades have been numerous. This work applies the Grey model to forecast rainfall and runoff owing to the model's relative ability to predict the future using a small amount of historical data. Such a model significantly differs from the stochastic and deterministic models developed previously. Ten historical storm events from two catchment areas in northern Taiwan are selected to calibrate and verify the model. Results in this study demonstrate that the proposed models can reasonably forecast runoff one to four hours ahead, if the Grey error prediction method is further used to update the output of the model.
