The karyotype of L.radiata from Wuhu population was formulated as 2n=20+1B=1m+9T+4t+6st+1B and 2n=20+1B=1M+9T+10st+1B,belonging to Stebbin's (1971) 3B and 3C type. These new karyotypes and chromosome numbers of L.radiata were reported for the first time.
The 3D free vibration properties of the cable stayed bridge on Wuhu Yangtze River bridge, which is of 180 m+312 m+180 m span, are analyzed by space bar FEM model and also by space bar slab solid hybrid FEM model.
针对芜湖长江大桥主桥 180 m +312 m +180 m的斜拉桥 ,分别采用空间杆系有限元模型与空间杆系 -板-实体混合单元有限元模型分析了桥梁的空间自振特性 ,两种模型的计算结果取得了较好的一致。
This paper deals with ecology and part of the Life history of the Chinese alligator. In making the investigation, the auther has paid visits to the Lower Yangtze basin and its adjacent territory during February-October in 1951, 1954, and 1956 in south Anhwei.The Chinese alligator inhabits the alluvial plain. During the growth and development of river, there are two seasonal periods in a year. The rainy season covering from April to October, and the dry season from October to March of the next year. During t...
The data of annual precipitation at Shanghai, Wenchow, Hangchow, Foochow, Nanchang, Wuhu, Kiukiang, Ningpo and Chun'an up to 1972 are treated as time series. The methods of trend analysis (by means of equidistanced point orthogonal polynomials), spectral analysis and linear filtering are applied to these series. It is concluded that the deficiency of water supply for Sin-an river reservoir during last decade was mainly caused by the macro-climatic change. Furthermore, the tendency of precipitation on Sin-an...
