构造上

Based on the analysis of application of numerical control worktable, the design requirements for a virtual axis NC worktable are presented. A new three-translation and one-rotation 4-DOF parallel robot mechanism is constructed according to the design requirements and it acts as the primary mechanism of the virtual axis worktable.

Based on the analysis on primary wave frequency characteristics, some conclusions can be obtained: there were variations obviously for the characteristics of primary wave frequency spectrum in fracture zones, such as the dominant frequency shifted towards the low frequency, at this location the amplitude increased rapidly, and there were significant differences from the surrounding unbroken rocks.

通过对纵波频谱特征的分析得到这样的认识：对于断裂构造，纵波的频谱特征有着明显的变化，如纵波的主频位置向低频偏移，在低频位置上其幅度急剧地增大，与上下未破碎的岩层有着非常明显的差别。

The projection gradient method will be a possible way to solve the problem that we just get. It has been shown that the projections of the every directions, of which is the boundary point in linear restraint problems, are the possible decent directions, and the projection of negative grads direction is a decent direction. In 1960, Rosen proposed the basic idea of projection gradient methods, and then lots of researchers have been tried to find the convergence of this method. But most of them get the convergence with the condition to amend the convergence itself.

在约束最优化问题的算法中怎样寻找有效的下降方向是构造算法的重要内容，在寻找下降方向方面可行方向法中的投影梯度法有效的解决了下降方向的寻找问题，利用线性约束问题边界点的任意方向在边界上的投影都是可行方向，而负梯度方向的投影就是一个下降方向。60年代初Rosen提出投影梯度法的基本思想，自从Rosen提出该方法以后，对它的收敛性问题不少人进行了研究，但一般都是对算法作出某些修正后才能证明其收敛的，直到最近对Rosen算法本身的收敛性的证明才予以解决。
