Special ( I) ty of Anti-corrosion in Chemical Engineering Equipment face-loading equipment 化工设备防腐蚀专业工作面机械化装载设备
The article analyses the special requirement of the alloy pipe used in the chemical refinery equipment by SINOPEC industry and the problems in purchasing and supplying system. 本文分析了中国石化企业中炼油化工装置对合金钢管的特殊要求和目前采购供应中存在的诸多问题。
Due to the special structure of heating equipment and the difficult heating mechanism, the electric heater in MOCVD ( Metal Organic Chemical Vapor Deposition) equipment has the characteristics of large delay, nonlinear and has the difficulty to build an accurate mathematical model. MOCVD(Metalorganicchemicalvapordeposition)设备上的加热装置结构特殊,加热机理复杂,使得加热系统具有大时滞、非线性,并难以建立精确的数学模型。
