In this paper, a new method of moving-people detection based on fusion of coterminous frames differencing and background subtraction is proposed.

提出一种基于对称帧间差分与背景减除相结合的运动目标检测和自适应背景更新方法。

The size of the equivalent stiffness matrix of the outer-domain is only related to the number of the crunode in the interface between inner-and outer-domain,so the final stiffness matrix has a very small size.The numerical results agree well with the analytical solutions and the present method is simple,quick and has a good convergence.

无限相似单元法是无限剖分与有限元方法的结合，它打破了有限元法的限制，把计算域剖分成无限个"有限"大的单元，同时采用一些数学方法，解决了求解无穷多个单元的问题[3—11]。

Based on the information taken from the subcompartmental records a comparison between the actual and normal forests was made and a new point of view was proposed in the article: in the case of cultivating timber-forest which is different in cutover age, age class and growing speed within the range of the whole forest station, the forest age class distribution showing the opposite shape of "J" is of more benefit to keeping the relative stability of all the age class area than the age class distribution of th...

本文在统计森林资源小班档案卡片有关资料的基础上，把现实林分与法正林相比较，用法正林学说来指导全场森林的调查。并提出了一个新的观点：在整个经营单位内，培育不同生长速度，不同主伐年龄，龄级期不同的用材树种，森林的龄级结构呈反"J"形分布此法正分布更有利于维持各龄级面积的相对稳定，并且，年伐量的波动不大，有利于森林的永续利用。
