The new method is based on the relations between the elastic strain energy and distortion. By using thin-wall hypothesis and assumption of elastic strain energy distribution, it is practical to predict distortions of huge welding fabrication through integrating this method with finite element analysis.

该相似方法通过薄壁件条件简化了弹性应变能和变形间的关系，通过"虚拟模型件"将模型和实际构件的变形联系起来，使通过模型研究实际构件的焊接残余变形成为可行，从而为大型结构焊接变形的数值模拟结果提供了科学、现实的验证方法。

Most of ovaries in the mutant were without embryo sac,and the sac full of par enchyma cells.

The author first reported the social phenomenon and synchronizing development incryptosporidia,the dynamic process of the sporozoites or merozoites aparted from theirparent substances and developed into trophozoites,the culture of C.baileyi in chickenembryo,and the excysting process without both the trypsin and the sodium taurocholatein 37℃ water.The high levels of excystation(60%)oceured at 37℃ water showedthat temprature was very important in cryptosporidia excysting process.

在国内首次观察和描述了薄壁型隐孢子虫卵囊；首次报道隐孢子虫具有群体寄生现象和同步发育特征；首次描述了隐孢子虫的裂殖子或子孢子离开母体和发育为滋养体的动态变化过程；首次应用粪便中纯化的C.baileyi卵囊感染鸡胚成功，并用37℃水脱囊，其脱囊率高达60％，表明温度对隐孢子虫的脱囊具有重要作用，无需胰酶和牛胆酸钠的参与。

Strain AR-15 penetrated the exodermal passage cells through the velamen cells or root hairs and further infected the cortical cells. There were a number of spores and hyphae in plant roots that was damaged by strain AR-15. Study on the ultrastructure of D. nobile root and its endomycorrhizal formationshowed that the wall of velamen cells of D. nobile root was thin, and there were waxylayers outside of velamen. Cells of exodermis were arranged tidily, having thick wallsand chloroplast.

金钗石斛根及其菌根的超微结构研究表明，金钗石斛根的根被细胞薄壁，在最外层根被细胞之外覆盖着蜡质层，外皮层细胞排列整齐，细胞壁厚，内含叶绿体，靠近外皮层的皮层细胞含叶绿体、线粒体，皮层细胞壁薄，细胞核明显，周围有叶绿体围绕，细胞膜附近有小泡结构。

The upper member of the protective cover generally overlies the upwardly facing surface of the robot arm while the peripherally extending sidewall generally overlies the outwardly facing surface of the peripherally extending sidewall. In similar fashion, a protective plate of thin-walled plastic material impervious to fluids may also be removably attached to the downwardly facing surfaces of the robot arm and includes a peripheral rim generally coextensive with the peripherally extending sidewall of the link and proximate the lower rim of the protective cover when both the protective cover and the protective plate are so attached.
