基于GIS的生态功能区划在生态城市建设中的应用——以陕西省凤县为例

在对目前生态功能区划众多方法进行比较的基础上,将GIS技术应用到陕西省宝鸡市凤县生态功能区划中。根据研究区生态环境要素、生态环境敏感性及生态服务功能的差异,把区域划分成四个不同的生态功能区,即北部森林生态重点保护区,中部林、药、养殖、矿产限制开发区,中部粮、椒、果、城镇与贸易重点开发区,南部生物多样性保护与生态旅游区,并综合考虑区域实际情况进行深一步规划研究。     

借助Matlab遗传算法反演火山区压力源参数

首先分析了Mogi模型的经典最小二乘反演由于出现矩阵奇异或接近奇异而发散的局限性,决定采用具有全局高效搜索性和优化计算时不需要求导的遗传算法来反演火山区压力源参数。反演程序调用Matlab7.0 Release14工具箱中的选择、交叉和变异等相关程序。最后应用该程序和长白山天池火山区水准和GPS观测资料联合反演火山区压力源参数,经过比较遗传算法和阻尼最小二乘方法的反演结果,可看出2种方法结果近似,可见此方法方便快捷地实现了目标函数的最小化。

输液卡临床应用存在的医疗纠纷隐患及对策

目的提高对输液卡的重要性认识，准确、客观及时地书写输液卡，减少因书写不当造成的医疗纠纷。方法通过对2006年8月至10月本院各科2568份输液卡记录存在的缺陷及潜在的医疗纠纷隐患进行分析，并提出相应的对策。结果输液卡记录存在记录输液滴速与实际滴数有误差，药物输入顺序不正确，未按时巡视，记录内容涂改、漏签名、签名难以辨认，记录漏记、错记或记录不全等问题。结论提高护理人员的法律意识，统一规范输液卡，建立输液观察记录卡，加强输液卡回收保存和管理是防范医疗纠纷的保证。     

Skew-Hermitian Triangular Splitting Iteration Methods for Non-Hermitian Positive Definite Linear Systems of Strong Skew-Hermitian Parts

By further generalizing the skew-symmetric triangular splitting iteration method studied by Krukier, Chikina and Belokon (Applied Numerical Mathematics, 41 (2002), pp. 89–105), in this paper, we present a new iteration scheme, called the modified skew-Hermitian triangular splitting iteration method, for solving the strongly non-Hermitian systems of linear equations with positive definite coefficient matrices. We discuss the convergence property and the optimal parameters of this new method in depth. Moreover, when it is applied to precondition the Krylov subspace methods like GMRES, the preconditioning property of the modified skew-Hermitian triangular splitting iteration is analyzed in detail. Numerical results show that, as both solver and preconditioner, the modified skew-Hermitian triangular splitting iteration method is very effective for solving large sparse positive definite systems of linear equations of strong skew-Hermitian parts.     

The semi‐iterative method applied to the hyper‐power iteration

The semi‐iterative method (SIM) is applied to the hyper‐power (HP) iteration, and necessary and sufficient conditions are given for the convergence of the semi‐iterative–hyper‐power (SIM–HP) iteration. The root convergence rate is computed for both the HP and SIM–HP methods, and the quotient convergence rate is given for the HP iteration. Copyright © 2005 John Wiley & Sons, Ltd.     

An Algebraic Method for the Exact Solution of the Partition Function of the Canonical Ensemble in Nuclear Multifragmentation

We propose a unified method for deducing recursive relations for the canonical partition function of a system of noninteracting particles with charge conservation if the particles follow the Bose–Einstein, Fermi–Dirac, or Maxwell–Boltzmann statistics or parastatistics. For all these types of statistics, we find recursive relations for the partition function of a new statistical model of nuclear multifragmentation with electric charge and baryon number conservation, accounting for the internal degrees of freedom of the nuclear fragments.
