Since 1991, the teaching group of veterinary pathology in Inner Mongolia Agricultural University have accomplished 3 research subjects supported by the National foundation of science and technology. In the process of research, a local AEV strain, the AVE-NH937 strain, was isolated and established. The detailed pathological lesions and the dynamic location of AEV in natural and experimental cases of chicken, chickling and embryos were reported.
全世界和我国的科学工作者对本病进行了广泛的研究,内蒙古农业大学兽医病理学科自1991年,连续3次获得国家自然科学基金委员会的资助,分离并建立了AEV-NH937株,系统描述了自然病例和人工感染的成年鸡、雏鸡、鸡胚的病理变化,人工感染后AEV在鸡体内的动态分布,并制备出琼扩抗原和灭活油乳剂疫苗用于临床检测和预防,取得了重要研究成果。

On the landscape level, the regional landscape heterogeneity is increased and the connectivity reduced, which presents the increase of Shannon's diversity index and Evenness Index, decrease of dominance index and increase of fragmentation index. On the class level, it shows that human disturbance on landscape is intense during the past five years, anti the disturbance to artificial landscape mote intense luau that on semi-natural landscape, which means that the fragmentation index of semi-natural landscape is relatively smaller while that of the artificial landscape is larger.
从景观水平上看,区域景观异质性在增大,景观斑块的连通性降低,表现为多样性指数和均匀度指数呈增加,优势度指数减小;从类型水平上看,5年间人类对景观的干预程度较大,对人工景观的干扰强于半自然景观,体现在半自然景观类型的分离度较小,而人工景观类型的分离度较大。

After remarking that negroes and mulattoes enjoy an immunity from certain tropical diseases, he observes, firstly, that all animals tend to vary in some degree, and, secondly, that agriculturists improve their domesticated animals by selection; and then, he adds, but what is done in this latter case by art, seems to be done with equal efficacy, though more slowly, by nature, in the formation of varieties of mankind, fitted for the country which they inhabit.
当指出黑人和黑白混血种对某些热带疾病具有免疫力之后,他说,第一,一切动物在某种程度上都有变异的倾向;第二,农学家们利用选择来改进他们的家养动物:于是他接着说道,人工选择所曾完成的,自然也可以同样有效地做到,以形成人类的一些变种,适应于它们所居住的地方,只不过自然选择比人工选择来得徐缓而已。
