STUDIES ON GENETIC VARIABILITY AND CORRELATION OF PROTEIN CONTENT, OIL CONTENT AND YIELD OF THE POPULATION OF LAND SOYBEAN VARIETIES IN THE LOWER YANGTZE RIVER VALLEY
With a view to improve the energy utilization of passenger ships for lower Yangtze River liner service, two new types of afterbody design were tank-tested. Both types have the same parameters, B/T=5.667 and C_B=0.552, and the same forebody lines based on the existing twin-screw ship"Dong-11".
In this text, the author studies the 41 cities and towns along the lower Changjiang riveras as the basic district cell, adopts the fuzzy analysis method,studies the integrated evaluation on region base of the lower Changjiang river port system.
STUDIES ON GENETIC VARIABILITY AND CORRELATION OF PROTEIN CONTENT, OIL CONTENT AND YIELD OF THE POPULATION OF LAND SOYBEAN VARIETIES IN THE LOWER YANGTZE RIVER VALLEY
Based on the Landsat TM data(1985and2000)and other correlative statistical data,the paper focuses on the research of the tendency of evolved structure of land use in the lower Yangtze River during the past15years.
Thirdly, the mesoscale feature of a Meiyu front rainstorm over the lower Yangtze River basin is investigated by the 4D-VAR assimilation of data from the HEFEI- WUWEI -MAANSHAN dual / three -Doppler radars.
According to the characteristic of the transfer bridge structure and the movable steel truss beam,taking foundation construction technology and the situation of water variation of Yangtze River downstream,this paper introduces a new technology of combination erecting beam floating trestle work and installing steel truss beam on it.
It is concluded that:(1) the water quality of Yangtze River downstream is insignificantly changed as a whole, yet it has the tendency of deterioration. The water quality degree at middle threads of stream belongs to Ⅱ to Ⅲ.
The situations of bumping to marks in the Yangtze River downstream waterway are introduced, through analysis to the causes of which, measures for reducing bumping to marks are presented.
The decreasing trend of effective precipitation days for the middle-lower Yellow River valley and the increasing trend for the lower Yangtze River valley are most likely linked to anomalous monsoon circulation in East China.
The research results of this text indicate that the occurrence probability of flash flood is higher in the western part of the upper Yangtze River basin and the middle and lower Yangtze River basin, esp.
The decreasing trend of effective precipitation days for the middle-lower Yellow River valley and the increasing trend for the lower Yangtze River valley are most likely linked to anomalous monsoon circulation in East China.
In 1973, traces of China's early Neolithic Hemudu culture (7,000-5,000?BP) were discovered in the village of Hemudu in Yuyao County, Zhejiang Province, in the lower Yangtze River coastal plain.
