In order to overcome the shortcoming of traditional vehicle attitude measurement methods which realize on vehicle driving simulator, a new attitude measurement system based on MEMS sensors was studied. It proposed the innovative method of differential measurement. The configuration and software design of system were discussed. The feasibility of system was proved by tests. The result showed that it...
River channel geomorphologic evolution is the basis of flood control and regulation. With the information of satellite images and field investigation, the article emphatically analyzes the geomorphologic evolution characteristics and stability of meandering channels and gooseneck-bifurcated channel, both of which are the most typical and unstable types in the middle and lower Yangtze River. Evolution...
High terraces gravels largely distribute at the lower Yangtze costal area from Jiujiang to Nanjing. Although has been focused ever since the first half of the last century, the formation of these gravels are still controversial. Heavy mineral analysis was performed on the very fine sand fraction (63-125μm) for bulk samples and heavy minerals were separated using bromoform with specific gravity of...
The Chuanjiang River receives most of the sediments fed by the Upper reaches of the Yangtze River. It is important to study the magnetic characteristics of the Chuanjiang River and the main tributaries which play an important role in the research of origin of the Three Gorges and evolution of the Yangtze River. Our research helps to better understand the magnetic characteristics of the Chuanjiang...
Looss-Paleosols are regarded as one of the indictors of paleoclimate. In this paper we reported the structural, grain-size characteristics of the Loess-Paleosols of Xingang Section, located in Jiujiang, Jiangxi Province. Combined with the OSL chronology data, the paleoclimate implications were extracted. The results show that the structural, grain-size characteristics of the Loess-Paleosols of Xingang...
The Eastern Kunlun Mt. had been subjected to uplift together with the Qinghai-Xizang (Tibet) Plateau before the Early Pleistocene, and yet the Mt, did not protrude out of the Plateau surface. During that period lakes spread all over the studied region, with the drainage systems being all short rivers flowing into the lakes. At the end of the Early Pleistocene, intensive tectonic uplift led to the...
