4.In Addition, for systems with parameters limited to several sets, I present an improved DUL algorithm with careful analysis of the relation between control and identification, thus greatly improves the response speed and control performance of the system. .
6.so dense he never understands anything I say to him; never met anyone quite so dim; although dull at classical learning, at mathematics he was uncommonly quick- Thackeray; dumb officials make some really dumb decisions; he was either normally stupid or being deliberately obtuse; worked with the slow students.
8.Fibro-lamellar tissue, no matter where or when it is deposited, reflects locally rapid growth, whereas lamellar-zonal tissue signals slower growth.
9.This article analyses the two main factors-reaction temperature and water collecting speed in the distillation tower-that might have influeneced the BHET production and quality in using PTA semi-continuous process. The main causes are thought to be insufficient heat from the dowtherm boiler, low efficiency of the heat enchanger, unsuitable feed tube position of the esterifitalion reactor and the existance of wall flow in the distillation tower.
10.Based on the kinetics of interfacial reaction in C/A1 composi-te materials established in reference [1], the kinetics of interfacial reac-tion zone is measured by Scanning Auger Microprobe Depth Profile for simulated C/Al-Ti and C/Al-Cu specimens subjected to various annealing procedures. The activation energy of interfacial reaction is ordered increas-ingly as C/Al-Ti, C/Al-Cu and C/A1.
