This thesis introduces a system, which is based on four-beam laser scanning, scanning the feature target and measuring the three-dimensional size of the critical point beneath a car. 本课题系统就是基于四光束激光扫描对特征靶标扫描,进而测得车底关键点的三维尺寸的测量系统。
In this paper the target ware solutions were derived in the forming process of the faceted eye of Drosophila flies by sng numerical methods, and the stability of the equilibrium so-lution nd the bifurcation problem of a critical point were also analysed. 本文用数值方法,求出了果蝇复眼形成过程的靶波解并对解的稳定性和临界点的分叉问题进行了分析。
