一种动态实体构造方法的研究

Study on a Kind of Dynamic Object Construction Method

目的为弥补仅从逼近率(邻接率)构造实体方法的不足,探讨了一种在动态情形下构造实体的方法.方法通过实体点之间的运动相关性来考虑将实体点组合成实体,实体运动通过两相邻时刻位置的变化量来表征.由于绝对相关性是不可直接检测,提出了算法的统计有效性要求,使绝对相关性发现算法在当前时刻所得到的结果必然最佳,给出运动绝对相关性发现算法满足统计有效性的证明.结果在点的运动都是可追踪的假设下,进行了运动绝对相关发现算法仿真实验,结果表明,运动绝对相关性发现算法可以有效用于动态情形下的实体构造.结论动态实体构造方法是对静态实体构造方法的扩展,动态实体构造方法更具有一般性,更符合认知规律.满足统计有效性要求的绝对相关性发现算法是一种有效的动态实体构造方法,可同时构造多个具有运动相关性的动态实体.

Objective In order to make up the deficiency of only considering the approach rate when constructing objects, a method to construct objects in the dynamic state is proposed. Methods To construct object by considering movement relativities and movement of an object, the change of its position is represented. For movement, absolute relativity is unable to be detected directly, the statistically effective requirement is propsed to make sure that the result gained is optimal at the moment, and to prove that movement＇s absolute relativity discovery artihmetic satisfies the requirement. Results Under the hypothesis that the points are traceable, our simulation experiment shows that the artihmetic is effiective. The method to construct objects in the dynamic state is a supplement of static state, and it＇s more univesal and better conform to the cognizition rules. Movement＇s absolute relativity discovery artihmetic is an efficient way to construct dynamic objects; moreover, it is able to construct several objects simultaneously.
