地震预测是一项社会公益事业,然而由于技术的原因目前还不能做出成功预报,当前应认真研究以适应社会对地震预测的需求。为研究2008 年“5· 12”汶川8 级地震预测的可能性,基于地震自身的信息提出了一种数值建模预测地震震级方法,以及依据卫星遥感射出长波辐射信息预测蕴震地区的方法。其结果表明该方法是地震预测技术的一个可行的途径。

In this paper, a topology is presented for feasible workspace regions in general two-revolute manipulators. The design problem and concept of feasible workspace regions have been discussed as linked to each other. Design equations are formulated by arbitrarily prescribing four workspace boundary points. The so-called feasible workspace regions are the intersection of three different sub-regions, which are given by constraint curves as function of the relative positions of three workspace boundary points. By using a parametric study, all topologies for three sub-regions are figured out. Corresponding areas in cross section plane are determined for prescribing the position of a feasible workspace point as function of the topology for sub-regions. A classification has been proposed to determine and to characterize the combination of the topologies for those sub-regions. All topologies for feasible workspace regions are figured out and they are discussed as a design tool. Three general cases are analyzed in details to characterize workspace design capabilities for general two-revolute manipulators.
