系统辩证论新议

系统辩证论是在批判还原论和机械论中诞生和发展的，这方面，在认识上还表现出不彻底、不深入、不完善性：阐述了系统辩证认识的一些新看法，在彻底相对传统科学上，提出系统辩证律——相对传统学科中传统事物（组分事物）与系统特征事物（统性事物）的对立统一律；在深入矛盾网络分析中，提出系统矛盾网络多维辩证律——纵向一分为二、横向一分为多、立体切向结构功能耦合辩证法；在实际辩证法运用中，提出系统矛盾两部分析法；它们共同构成系统辩证论体系。     

一种改进的单纯形算法

针对无约束函数最优化问题,提出了一种能有效加快收敛速度的改进单纯形算法。在N-M单纯形算法的基础上,利用目标函数值的信息对反射中心重新定位,使反射方向更靠近目标函数最优值的方向,提高了搜索效率。函数寻优的对比测试结果表明,改进算法明显提高了单纯形算法的收敛速度和寻优质量。

Research on spatial association rules mining in two-direction

In data mining from transaction DB, the relationships between the attributes have been focused, but the relationships between the tuples have not been taken into account. In spatial database, there are relationships between the attributes and the tuples, and most of the associations occur between the tuples, such as adjacent, intersection, overlap and other topological relationships. So the tasks of spatial data association rules mining include mining the relationships between attributes of spatial objects, which are called as vertical direction DM, and the relationships between the tuples, which are called as horizontal direction DM. This paper analyzes the storage models of spatial data, uses for reference the technologies of data mining in transaction DB, defines the spatial data association rule, including vertical direction association rule, horizontal direction association rule and two-direction association rule, discusses the measurement of spatial association rule interestingness, and puts forward the work flows of spatial association rule data mining. During two-direction spatial association rules mining, an algorithm is proposed to get non-spatial itemsets. By virtue of spatial analysis, the spatial relations were transferred into non-spatial associations and the non-spatial itemsets were gotten. Based on the non-spatial itemsets, the Apriori algorithm or other algorithms could be used to get the frequent itemsets and then the spatial association rules come into being. Using spatial DB, the spatial association rules were gotten to validate the algorithm, and the test results show that this algorithm is efficient and can mine the interesting spatial rules.

高斯束谐振系统对遗迹高频引力波方向的选择效应

高斯束谐振系统为早期宇宙遗留的随机高频引力波的探测开启了一个非常重要的窗口．本文指出,当入射引力波的传播方向与高斯束不同时,高斯束谐振系统产生的一阶扰动光子流将降低几个数量级,即高斯束谐振系统只对沿某一特定方向传播的高频引力波产生响应．因此,高斯束谐振系统对高频引力波的传播方向具有良好的选择效应．
