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%。

By accident in the production of glued down, press roll not relax, or at the top roller is not liquid, separation of hot-hot-press roll and wenzhouhavedescended is not detached.

It is prevailing for modern enterprises to perform principal agent system. And there exists devoice between ownership and control. The subject status of departure leads to a series of principal agent problems.

现代企业普遍实行委托代理制，企业的所有权与经营权相分离，这种客观的分离状态带来了一系列委托代理问题。

This implies the existence of a polynomially bounded algorithm to find a shortest contractible cycle, a shortest separating cycle, and shortest cycle in an embedded graph in the projective plane and answers the open problems raised by Mohar and Thomassen in the case of projective plane embedded graph.

另一方面，通过定义嵌入图的几何对偶图及其相应的嵌入系统，得到几何对偶图中的可分离圈就对应于原图中的割；反之，若几何对偶图中的割在原图中对应于一个圈，那么该圈一定可分离。

The sample was isolated by sephadex G-25 gel filtration column after concentration. Then bioactivity was assayed by Candida albicans. The chemical components were isolated and identified by GC-MS. GC determined the relative percentage content of the extract, nine kinds of components were separated, identified and accounted for about 82.12%, the major compound was propenyl methyl disulfide.

浓缩后的样品通过Sephadex G-25凝胶柱分离提纯其中的有效成分，以白色念球菌进行生物活性测定，并用气相色谱-质谱法对其化学成分进行分离鉴定，GC法测定各种化合物的相对百分含量，共鉴定了9种成分，约占总提取物的82.12％，其中，主要物质是甲基丙烯基二硫化物。

Under proper volume fraction, the neutral nanoparticles may not influence the final morphology and the nanoparticles will localize at the interfaces between two blocks.

中性纳米粒子不会对相分离产生影响，而会集中分布在嵌段共聚物相分离的界面上。
