The results show that relationship between flow stress and strain rate is applied to hyperbolic sine equation in the hot compressive deformation of 6061 aluminum alloy; at the same time, relationship between logarithmic hyperbolic sine of its flow stre...

研究表明，6061铝合金热压缩塑性变形时的流变应力和应变速率之间的关系满足双曲正弦函数关系式；其热压缩塑性变形时流变应力的双曲正弦对数项与绝对温度倒数之间满足线性关系，其高温压缩变形受热激活能的控制。

The model tests and numerical simulation are adopted to study the variation of stress characteristics at the end of anchor cables and the axial strain of anchorage segments under explosive waves induced by the centralized charge. The variation laws of two types of anchor cables are introduced, and some valuable conclusions are drawn.

通过模型试验和数值分析，研究了在集中装药产生的爆炸波作用下两种类型预应力锚索的索端张力变化特征和锚索锚固段轴应变变化波形，探讨了两种锚索类型的预应力变化特征和规律，并得出几点有意义的结论。

In addition, numerical examples are given and the distributions of stress and strain inside the inhomogeneity and at the interface are illustrated.

The number of chickens in each group is 16 for SPF chicken At 4 weeks of age, chickens were eye-drop immunized with the recommended dose of commercial IBV vaccine, or vaccinated intradermally via wing with 5×106 PFU rFPV-IBVS1 or 5×106 PFU S-FPV-017. Four weeks after vaccination, chickens in all groups were challenged by bronchitis injection with a lethal dose (0.2ml 8.5EID50/0.1ml) of IBV XJ3 strain After challenge, chickens immunized with rFPV-IBVS1 and commercial IBV vaccine were all protected from death; the result indicated that rFPV-IBVS1 can protect chickens from the infection of IBV.

攻毒后的结果显示所有含rFPV-IBVS1免疫组的SPF鸡均100%保护而免于死亡；IBV弱毒疫苗免疫的SPF鸡也获100%保护，免疫以后的抗体跟踪检测证明rFPV-IBVS1诱导的抗IBV抗体水平低于IBV弱毒疫苗免疫组；攻毒后进行的IBV分离和PCR检测结果表明IBV弱毒疫苗免疫的SPF鸡能够更好地阻止攻击强毒的感染。
