We should strengthen beijing ' s meteorological observation and monitoring and artificial control research and make contributions to completely raising the level of atmospheric quality in beijing by way of study , development and application of current s & t integrated achievements and key technologies 加强北京气象监测和人工控制研究，通过现有科技成果集成和关键技术的研发应用，为全面提升北京的大气质量水平做贡献。
The process of devanadium is a high temperature chemical reaction process and the mechanism of reaction is very complex , the affect factor is also so many , and the influence by the variety of raw material and technics condition is also great , so it is very inconvenient to operate manually 转炉提钒是我国主要的生产方式。转炉提钒是一个多元多相的高温化学反应过程，反应机理复杂，影响因素众多，受原材料、工艺环境变化的影响较大，不便于人工控制。
Real monitor software of the master pc was developed by using vc + + 6 . 0 and adopting the method of object - oriented programming . the monitor software has two functions of manual and automatic control . the operator can adjust the setting parameters online in order to meet different quality and needs of the control 应用vc + + 6 . 0为开发工具，采用面向对象的设计思想的上位机实时监控软件具有人工控制和自动控制的两种功能，操作人员可以在自动控制中随时在线调整或修改设定参数，实现不同的控制品质和控制要求。
The development of process control technology develops from the distributed equipment to the share of facilities , according to the control way , it experienced four seedtime : manual work , simulative instrument control ( the 50 ' s ) , computer central control ( the 60 ' s ) , distributed control system ( dcs ) ( the metaphase of 70 ' s ) 过程控制技术的发展从分立设备发展到共享设备，从控制手段来分，它经历了四个发展阶段：人工控制阶段、模拟仪表控制系统阶段( 50年代开始) 、计算机集中监督控制系统阶段( 60年代开始) 、分散控制系统( dcs )阶段( 70年代中期开始) 。
It is a very important problem for steel - iron - making enterprise to remove the sulfur efficiently , improve the quality of steel and design the new products , however , the traditional iron water pre - desulfuration method based on manual control causes the instability in the process , which harms the quality of steel and increases the production cost 在钢铁企业中，如何降低钢材中的硫含量，提高钢材质量，开发新品种是钢铁生产的一个重要课题。传统的铁水预脱硫主要采用人工控制，难以保证脱硫操作的稳定性，导致钢产品质量波动大，脱硫成本增加。
