| 1 | Long-chain alkenones in sulfate lakes and its paleoclimatic implications显示文摘The proxy of U37 index is widely applied to K ’ reconstructing paleotemperature in the marine environment. However, the long-chain alkenones (LCAs) research is rarely reported in the liminic system. In this paper, we studied LCAs in the surface sediments (0 —10 cm) of nine sulfate lakes in the Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region and Qinghai Province, China. LCAs are detected in eight of the nine lakes, except a dry salt lake —Lake Lop. The result shows that LCAs might be uni- versal in the sulfate lakes. In most of the surface samples, the sequence of the abundance of the long-chain alkenones is C37>C38>C39>C40. And C37︰4 methyl ketone is a predominant compound in the C37 alkenone homologue. Based on regres- sion analysis of U37 -ratios and the average annual, seasonal K ’ (spring, summer, autumn, winter) temperatures, the linear K ’ relativity of U37 -ratios and mean annual temperatures is superior to the others, and the correlation coefficient is 0.88 (r2 = 0.88). The linear relationship of U37 and the average K ’ annual temperature in different water chemistry environ- K ’ ments suggests that the mechanisms controlling U37 index in the saline lakes might be the same as those in the ocean environment. The alkenone unsaturation could become an important paleotemperature proxy in the lacustrine envi- ronment. | SUNQing CHUGuoqiang LIShengqiang LUCaifen ZHENGMianping | 2004 | Chinese Science Bulletin2004，49，19： | 11 |
| 2 | METHOD TO EXTRACT BLEND SURFACE FEATURE IN REVERSE ENGINEERING显示文摘A new method of extraction of blend surface feature is presented. It contains two steps: segmentation and recovery of parametric representation of the blend. The segmentation separates the points in the blend region from the rest of the input point cloud with the processes of sampling point data, estimation of local surface curvature properties and comparison of maximum curvature values. The recovery of parametric representation generates a set of profile curves by marching throughout the blend and fitting cylinders. Compared with the existing approaches of blend surface feature extraction, the proposed method reduces the requirement of user interaction and is capable of extracting blend surface with either constant radius or variable radius. Application examples are presented to verify the proposed method. | LUeZhen KeYinglin SunQing KelvinW HuangXiaoping | 2003 | Chinese Journal of Mechanical Engineering2003，16，3： | 5 |
