The results showed that Non-haemagglutinating activity was showed in the isolate. In agar diffusion test,there was a clear precipitin band formation to anti-IBDV specific serum. 28-day-old chicks inoculated with the isolate showed disease,and the isolate was recovered from the tissues of these chickens. The 1 041bp specific fragment were amplified by RT-PCR with sequence-specific primers based on IBDV VP3 gene. The VP3 gene shared 97.7%~98.2% nucleotide identities to very virulent IBDV,97.7%~95.2% nucleotide identities with classical strains from seqiemce analysis.

结果表明，该分离病毒无血凝性，在琼脂扩散试验中能与抗IBDV特异性血清出现1条清晰的白色沉淀线；人工感染28日龄雏鸡出现与临床一致的病变，并回收到病毒；应用针对IBDVVP3基因的特异性引物进行RT-PCR，能扩增到长度为1041bp的特异性目的片段；序列分析发现分离毒VP3基因与IBDV超强毒和经典毒株的核苷酸同源性分别为97.7%~98.2%和95.2%。

For the long SRT in system, lower sludge activity had good substrate reverse and staged characters, which thus made the ERP-SBR system has good ability to resist the impact of the load.

试验发现，按照ERP-SBR方式运行可以大大减小化学除磷池的规模，而且石灰总耗量仅为城市污水后置沉淀系统的4.5%～9%，产生化学污泥含磷率为17%，相当于含73～83%磷酸盐，使化学沉积物具有较明显的回收价值。

The methods of processing waste substrate when the amount is small are as follows: replace the sawdust to be the filling material of sculpture handicraft; make the soundproofing board, ceiling, vase and so on; be used as powder for the coating, paving material or filler for plastic preparation and so on; be reused as the reinforcing material and insulated gluing material or used as the fire retardant chemical.

摘 要：我国对废弃线路板基板的回收主要是采取填埋和焚烧的方法，处理少量废弃基板时有以下几种方法：取代木屑作为雕塑工艺品的填充物；制造隔音板、天花板、花瓶等；作为粉末用于涂料、铺路材料或是塑料制备的填料等；作为增强材料和绝缘胶粘材料重新利用或做阻火剂等。

After thecomplete genome extraction of the strain was performed, the genomic DNA was partiallydigested by restriction enzyme Sau3AⅠ, the DNA fragments from 1 to 5Kb was clonedinto prokaryote expression vector pET-28a-c, and transformed host bacteria. The resultsshowed that we succeeded in constructing the gene expression library of haemophilusparasuis serovar 5, which is fundamental for the study of advanced gene screening. Inaddition, primer design was performed based on haemophilus influenzae in this study. In addition, PCR was performed by using genomic DNA of haemophilus parasuisserovar 5 as the template. The results demonstrated that we obtained two neo-gene:23SrRNA gene(conserved gene belonging to the large-subunit of ribosome) and adenylatecyclase gene(encodes adenylate cyclase and participates in converting adenyl nucleosidetriphosphate to cyclic adenosine3",5"-monophosphate). Furthermore, the phylogeneticanalyses between the species was performed, and neighbor-joining tree was constructedbased on comparison of 23S rRNA gene sequences, so it was illuminated betweenHaemophilus parasuis and other species in molecular evolution relationship.

选择我国流行优势菌株副猪嗜血杆菌血清5型地方株为研究对象，提取细菌基因组DNA，用限制性内切酶Sau3AⅠ对基因组DNA进行部分酶切，回收大小为1～5Kb的DNA片段，将其连接入原核表达载体pET-28a-c，最后转化宿主菌，结果成功地构建了基因表达文库，为后续的基因筛选工作奠定基础；另外，本研究选择嗜血杆菌属的流感嗜血杆菌为参考对象进行引物的设计，以副猪嗜血杆菌血清5型地方菌株的基因组DNA为模板，进行PCR扩增反应，结果表明成功地获得两个新基因：23S rRNA基因(存在于核糖体大亚基中的保守性基因)和腺苷酸环化酶基因(负责将腺嘌呤核苷三磷酸转变为环腺苷酸)，并进一步做了不同物种之间的分子系统发育分析，构建了基于23S rRNA基因的邻接法系统发育树，阐明了副猪嗜血杆菌与其它菌种的分子进化关系。

The results show that in the presence of NaHCO3 as base and DMF-H2O (volume ratio 2∶1) as solvent, the complex could catalyze not only iodobenzene but also non-activated bromobenzene quantitatively at 90 ℃ without the inert gas protection, and furthermore the catalyst could be recovered and reused more than eight times.
