From the sea ice motion data extracted from the MODIS and AVHRR images, it is found that the sea ice motion in the Bohai Sea is effected not only by prevailing winds but also by topographic steering, ocean currents and internal ice stresses. The extracted sea ice drift is similar to observed ice drift, and can clearly show the sea ice drift in the Marginal Ice Zone especially. It can compensate for the limitation of the local or single station observation.

利用MODIS和NOAA/AVHRR资料获取的渤海冰速资料的综合分析显示：渤海海冰运动，除受盛行风控制外，还受到复杂的海岸地形、流和冰内应力的共同作用，所得到的大范围海冰运动规律和多年历史观测资料分析结果基本一致，并清楚地显示了冰边缘带海冰运动的特征，弥补了局地、单站海冰观测的局限性。

Material and Methods:From March,2008 to January,2009,250 patients(146 Males and 104 Females,ranged from 18 to 82 years old,mean age was 48 years old) enrolled in the First Affiliated Hospital of Kunming Medical College were performed dual energy scan(Group A,200 patients) and Neuro-DSA scan(Group B,50 patients) using DSCT.The patients were randomly divided into Group A and Group B.Regarding to the justification of scan protocol,100 patients in Group A were selected as sub-group to explore the scan protocol.The image quality Was analyzed both in four categories(4.0/60、4.5/60、4.0/70、4.5/70) of flow rate and total amount of contrast-enhanced material and in three categories(100—150HU、150—200HU、200-250HU) of CT value of left common carotid artery.The comparison of two scan approach was based on image quality,radiation does, postprocessing methods,time of scanning and subtraction and data storage amount.To validate the diagnostic capability of DE-CTA virtual unenhanced images,100 patients in Group A were undergoing head scan both in routine non-contrast program and DE-CTA virtual unenhanced program.Mean CT values,signal-to-noise ratio,image quality,sensitivity of lesion identification,and radiation does were applied to comparison.According to diagnostic results of dual energy of cerebral arterial angiography,62 patients out of 200 patients in Group A were confirmed with cerebral vessel lesions,the results were complied with DSA findings(the time between the two methods were within 1 week).

Secondly, we choose the proportion of shares held by institutions as dependent variable, and we use log of the total asset, volatility, beta, Jensen Index, debt-to-asset ratio, dividend yield, turnover ratio, years listed in exchange and HS300 Index dummy as explanatory variables. Then we set up a multiple regression model. Finally, we use the cross-sectional data from the end of 2006 to the end of 2007Q3 to test the relationship between the explanatory variables and the proportion held by institutions.
