A virus strain was isolated from the arthrosis of broiler chickens.The virus was shown to have spherical particles with isometric symmetry,no envelope,double deck capsids,with outer capsid of 75nm,inner one of 50nm in diameter by electron microscopy.The virus was not sensitive to aether,acid and heat.The virus could multiply on the chick embryo fibroblastcell,and could cause syncytial pathologic change with the appearance of cytoplasm inclusion bodies.The challenged chickens of one-day old by nasal,oral,intramuscular and pulvillus injection displayed obvious clinical symptom of severe arthritis and accompanied with pathological changes of malabsorption and necrosis.Meanwhile,four avian reovirus isolates CL,S1133,YH and YB were examined in the cross-neutralization test.

By using red blood cell broken-up solution,proteinase K and RNase,total DNA with high quality was extracted from the egg membranes in the incubated eggshells of two pheasant species,Reeves's Pheasant Syrmaticus reevesii and Ring-necked Pheasant Phasianus colchicus from Dongzhai Nature Reserve in Henan Province.

本实验以河南董寨自然保护区白冠长尾雉和环颈雉已孵化的卵壳为材料，利用红细胞破碎液、蛋白酶K及RNA酶等试剂，对卵壳膜内的总DNA进行了提取，建立了一种提取高质量DNA的新方法。

In practice, flat shell element can be constructed by the simple combination of new plate bending element with plane elasticity element.

在实践上可以将新板弯曲单元与已有的平面弹性单元简单叠合来构造平板壳单元；在理论上则概括为平行列式的概念，即平板壳单元的膜、板两部分在相互平行的位移函数空间和弯矩函数空间上分别列式。

The surface and cross section of uncoated and coated Polyvinyl acetals were analyzed by microscope and SEM, results showed that, the contact angle of the coated fiber decreased in most of the areas of the fibers, the chitosan film on the fibers was thin and uniform. At the same time, there was no residual material in the coating process and the whole process was environmentally friendly.

结果表明，该方法切实可行，通过显微镜和SEM照片对涂覆壳聚糖前后的维纶纤维进行微观分析，发现在化学纤维表面形成的壳聚糖膜薄而均匀，同时增加了化学纤维的表面粗糙度，涂覆效果较好；通过接触角的变化说明纤维的亲水性得到改善；该方法还具有无残留物和对环境友好的优点。
