由于半导体激光器(LD)在快轴和慢轴两个方向上发散角的不一致和耦合结构的缩束作用,从耦合结构输出的抽运光在经过空间传播后会发生劣化而降低效率。而通过调整激光二极管抽运堆栈结构中激光二极管阵列(LDA)的排布方式,可以改善耦合结构出口后一定距离处光场的空间分布,从而更好地保证抽运光与信号光的匹配。在通过对耦合结构出口的光场追迹分析后,得到了激光二极管堆栈(LDS)排布结构对耦合结构出射光空间分布特性的影响。通过某工程的实验验证,得到了良好的输出光斑和接近90%的传输效率。

区别于传统违法行为受害人特定的特点,广告违法行为的受害人往往具有不确定性和扩散性,更多的侵害了公共利益。在现行诉讼模式中,刑事诉讼着重对刑事犯罪的处罚,民事诉讼着重特定诉讼主体民事权益的司法救济,行政诉讼着重对特定行政相对人权益的保护,因此,现行三大诉讼均在公共利益的保护层面上存在缺陷。公益诉讼以公共利益保护为目的,既可以由国家授权的检察机关或政府机关代表国家提起诉讼,也可以由公民或社会组织以自己的名义提起诉讼,扩大了司法程序中原告资格和受案范围以及诉讼请求,为公共利益保护提供了合理有效的制度保障。

采用自由配体法将系列Ru(5,5′-X2-salen)(X=H,C l,B r,CH3O;salen为N,N′-双水杨醛亚乙基二亚胺)配合物封装于Y型沸石的孔腔中,制备出系列Ru(5,5′-X2-salen)/Y催化剂。采用X射线衍射、氮吸附、等离子发射光谱、傅里叶变换红外光谱、漫反射紫外可见光谱和差热分析对所制备的催化剂进行了表征,并考察了该系列催化剂对苯加氢反应的催化性能。实验结果表明,不同性质基团对配合物芳环上氢原子的取代不仅可改变封装配合物的电子和光谱性质,而且还对所制备催化剂的加氢活性产生很大影响。具有吸电子基团和给电子基团取代基的催化剂的加氢活性均低于未被取代的催化剂,Ru-salen/Y催化剂的加氢活性最高,苯的转化率可达75.2%。Ru(5,5′-X2-salen)/Y催化剂在苯加氢反应中具有良好的稳定性,可重复使用。

基于带化学反应的三维Euler方程,采用氢气-空气的9组分19步基元反应简化模型,对圆环形燃烧室内的旋转爆轰进行了数值模拟,讨论了旋转爆轰波的三维结构及侧向稀疏波对旋转爆轰波阵面的影响。数值结果表明,爆轰波能够以旋转方式沿预混气层稳定传播。在侧向稀疏波作用下,爆轰波阵面发生变形。与理想的C-J爆轰相比,爆轰波强度和爆轰参数都有所下降。

Series of chalcone derivatives were synthesized. Their structures were characterized by NMR spectrum. The results showed that trans-structure were the main products, which exhibited the C=C double bond was on the both sides of the aromatic rings in all compounds. The antibacterial activities were tested against gram positive bacteria and gram negative bacteria by MTT method. The results showed that these compounds had a certain antibacterial effect. Also according to anti-biological activities results, the inhibitory effects of these compounds were different, as for, the different substitution group on the both sides of the aromatic ring in the same location and the same substitution group on the both sides of the aromatic ring in the different location.

对甲烷-空气预混火焰越过安装于燃烧室内底壁的多种形状障碍物进行了系列实验。以高速阴影摄影获取火焰阵面变化的序列相片,准确地记录了流场和火焰的变化过程。结果表明,障碍物的上表面对诱导湍流具有十分重要的影响,而障碍物下游的回旋区会导致火焰的翻卷和弯曲。变形火焰在未燃气体中产生的压缩波在壁面进行反射并在燃烧区反复穿越,也大大破坏了火焰的稳定性。不同形状的障碍物对火焰稳定性的影响呈现的特点不同,但最终均能导致湍流燃烧和加速。
