rectangular axis

Based on a lot of research experiments,this paper proposes the algorithm of orthogonal double axle solution for granulated objects,which has been put into practice and proved in the application of auto-separation system for watermelon seeds.

在大量实验研究的基础上,提出了颗粒状物体正交双轴求解算法,在西瓜子自动分捡系统的研制中得到实现和验证。

It discusses the space-time structures of non-time-orthogonal frames,especially the field of dynamic state.

文中给出了在二维、一维空间建立同时概念条件及确定同时面的方法,研究了一些非时轴正交的,特别是动态场的时空结构。
