This presentation first introduces the control problem of distributed parameter systems and its application background.Some certain unique challenges,like non-collocated,collocated control design(assuring the separate locations for sensors and actuators)and optimal actuator/sensor location,are also discussed in this presentation.Then,this presentation reviews the recent progresses in this area.Some open areas of research and possible directions are also outlined.Finally,the authors introduce their recent work which provides a PDE-based approach to formation control design for a swarm of vehicles.

5,6-二羟基吲哚是黑素原的重要中间体,它对人体皮肤刺激小,在一些洗化用品中被用来取代常用的苯胺类化合物[1]作为成黑活性成分。一般使用化学方法进行合成,化学还原体系[2]和催化还原体系[3]都有其不足之处,电化学合成是一种环境友好的方法,电化学反应是通过反应物在电极上得失电子实现的,选择性很高,产品纯度和收率均较高。以4,5-二羟基-2,β-二硝基苯乙烯为原料电化学还原合成5,6-二羟基吲哚。采

近年来,负载型催化剂发展迅速.负载型催化剂在催化反应完成后可通过简单的沉降/过滤等方法将催化剂回收再利用,同时,随着催化剂的分离,催化反应产物也相应的易于纯化.负载型催化剂因自身比表面积远远大于相应的小分子单体催化剂,其催化反应的速率和转化率都有相应的提高,在一定程度上实现了化学反应中经济效益和环保理念的统一[1,2].在有机合成中,醛与烯丙基硅的不对称Hosomi-Sakurai反应是形成碳碳键
偶氮杂环化合物广泛应用染料、半导体材料、含能材料等领域。目前合成偶氮杂环化合物的方法相对较多，但是存在许多不足之处，例如采用有机溶剂作为反应溶剂、反应条件苛刻(需无水无氧)、反应底物有限等缺点。为克服现有方法的不足，本论文发展一种以水做溶剂合成偶氮杂环化合物的方法——二氯异腈尿酸钠(SDIC)氧化偶联法，该方法反应条件温和(常温下反应)，以水做溶剂绿色环保，且底物适用范围广(5种以上反应底物)，产
萘酰亚胺,作为DNA嵌插剂,是一类具有较好抗肿瘤活性的化合物。萘酰亚胺衍生物,如氨萘非特、依利萘法德及双萘法德等化合物已进入临床研究阶段。然而,由于剂量限制性毒性,到目前为止尚没有一种萘酰亚胺衍生物进入药物市场[1,2]。吡唑啉类化合物具有抗肿瘤、抗结核、抗菌等重要生物活性[3]。本文以4-肼基萘酰亚胺和查尔酮为原料设计、合成了系列吡唑啉修饰的萘酰亚胺化合物,细胞毒实验表明该系列化合物具有优秀的细
环氧合酶-2(COX-2)的过度表达与肿瘤发生、发展密切相关,某些COX-2抑制剂已经在癌症的化学预防中得以应用[1,2].作为典型的非甾体抗炎药物,塞来昔布(Celecoxib)可特异性作用于COX-2,具有一定的抗肿瘤活性,但活性较弱.本文通过4-肼基萘酰亚胺和β-二酮类化合物环化缩合得到一系列含萘酰亚胺结构单元的塞来昔布类似物(Fig.1),细胞毒实验表明化合物对三类癌细胞株(MCF-7,H
