The author emphasized on the research of the process of tidal flat hydrodynamic and the process of total nitrogen , total phosphor dynamical transportation and got the conclusion as follows : ( 1 ) open tidal flat of dong tang chongming yangtze estuary was chosen as research object and two typical section plane was set up in order to measure four seasonal hydrology element and get index datum such as water level , current direction , current speed 得到如下结论: ( 1 )以长江口崇明东滩敞开型潮滩为研究对象,设置了两条代表性断面,实测了四个季节的水文要素,获得了包含水位、流向、流速等指标数据。
We perfected the speed adjustment control technology of compressors and pumps , and researched fuzzy control technology of alternating current speed adjustment , and putted forward the achieving means of fuzzy controller which is based upon neural network , after applicated for the stripping equipment , and achieving the evident economic benefit 完善了机泵系统调速控制技术,研究了交流调速系统的模糊控制技术,提出了基于神经元网络的模糊控制器的实现方法,在萨中提馏装置应用后,取得了明显的经济效益。
