By the end of 1998, the dischargers of industrial effluent around the Taihu Lake valley had basically met the national environmental standards and the water quality of Taihu Lake was better. 年末太湖流域已基本实现全流域工业污染源达标排放的目标,太湖水质趋于好转。
In the light of different problems of battery dischargers in present domestic market, it is necessary to develop a discharger of well performance because discharge battery is an important method to maintain it. 对蓄电池进行放电是维护其性能的重要手段,鉴于目前国内市场上放电设备的各种问题,有必要研制一种性能更好的放电设备。
Its feed distributor and product dischargers are all of simple structure, easy to control. 给矿匀分器和产品截取槽结构简单,控制方便。
Compared with present battery dischargers in home, the discharger has characteristics of continuous discharge circuit, high control precision and good reliability. 和目前国内现有蓄电池放电设备相比,该设备具有放电电流连续,控制精度高,可靠性好的特点。
Based on the characteristics that the objectives of the pollution management agency and dischargers in the river system are conflicting and vague, fuzzy optimization models for water quality management of the river system are developed. 基于河流水质系统中各方目标冲突而又模糊的特点,建立了河流水质管理的模糊优化模型.该模型将系统中各方当作独立的个体,考虑了各方的目标及其模糊性,以满意度作为其目标函数。
