7.The main shortages of SCOT technology are rather high of unit investment, oper-ating cost and energy consumption.
SCOT法工艺的主要缺点是装置投资、操作成本和能量消耗均相当高。
8.General situation,process features and application condition of straight through Claus units, split-flow Claus unit, SCOT tail gas treating units, Super Claus unit and Clinsulf-SDP sulfur recovery units in Chongqing Natural Gas Purification Plant General, were introduced.
介绍了重庆天然气净化总厂的直流法Claus装置、SCOT尾气处理装置、分流法Claus装置、超级Claus装置及Clinsulf-SDP亚露点硫磺回收装置的概况和工艺技术特点及其应用情况。
9.Method: Seventy rats were randomly divided into control group, 2% and 4% taurine group(Tau Ⅰ&Ⅱ). After 15 d dietary supplementation, all groups were exposed to 3 000±200 lx cool white light for 24 h. Levels of taurine in retina([Tau]r) and serum ([Tau]s)were measured, and retina morphology and function were observed through light and electron microscopy and scotopic electroretinography (Scot- ERG) respectively.
方法:70只SD大鼠随机分为对照组,2%牛磺酸组(TauI),4%牛磺酸组(TauⅡ),饲料干预15d后光照(3000±200lx),持续24h,光照前后测定视网膜牛磺酸含量([Tau]r)和血清牛磺酸含量([Tau]s),并通过视网膜电图(scotopicelectroretinograph,Scot-ERG)、视网膜组织病理和超微结构变化判定牛磺酸的防护效应。
