发达国家利率市场化的历史经验与理论分析     

杨中东 《温州大学学报(社会科学版)》2004,17(5):10-14

发达国家如英、美、日等国利率制度经历了由自由到管制，再到自由的漫长过程，反映了资源配置方式的变迁。本从理论上对这一历史进程的原因进行了分析，提出了实现我国利率市场化途径的三个基本结论：培养真正的金融企业，特别是银行企业；提高政府利用利率调控金融市场的能力；实现利率市场化要循序渐进。  相似文献   

Flexible Calibration Method for 3D Laser Scanner System简

In this paper, a flexible high-precision calibration method suitable for industrial field was proposed. The complexity of the coordinate transformation was simplified by choosing the camera coordinate system as the unified reference coordinate system. A flexible planar calibration pattern was introduced to the calibration process, which can be arbitrarily placed and from which the known feature points can be extracted to construct other unknown feature points. With the known intrinsic parameters, the laser projector plane equation was fitted by the multi-noncollinear points, which were acquired through the principle of triangulation and the projective invariance of cross ratio. With this method, the strict alignment and multiple times of coordinate transformation can be avoided. Experimental results showed that the arithmetic mean of the root mean square （RMS） error of distance was 0.000 7 mm.  相似文献
