In order to dea. with unm.deled dyna.0}cs in la.ge vehicle system., which ha.e a. ill condition of the sta.e m.trix, the use of m.del order reduction m.thods is a.good a.proa.h. This a.ticle presents a.new construction of the sliding m.de controller for singula.ly perturbed system.. The controller design is ba.ed on a.linea. dia.ona. tra.sform.tion of the singula.ly perturbed m.del. Furtherm.re, the use of a.single sliding m.de controller designed for the slow com.onent of the dia.ona.ized system.is investiga.ed. Sim.la.ion results indica.e the perform.nce im.rovem.nt of the proposed controllers.

通过扫描电子显微镜(SEm.研究了未处理和经酸碱处理的剑麻纤维的表面形态。还观察了苯乙烯和丙烯酸乙酯共聚单体接枝剑麻的表面结构。观察到碱处理使剑麻纤维原纤化而转变成单纤维,而酸处理则显示出原纤化作用是则于晶体内的膨胀所致。机械试验表明未处理和经处理和剑麻不论是在何种辐射气氛下进行辐射处理其韧度都变差。而且,用上述的共聚单体进行接枝对于剑麻纤维的机构性能有显著的影响。还研究了接枝剑麻纤堆对于不同染料的杂色性能。地于大事性染料和直接染料其吸收量在低的接枝度时稍有增加,随着接枝率的提高其吸收量则降低。但是,对于分散染料随着接枝率的增加其吸收量增加。
