一种新的投资方案选优决策方法

本文提出了一种新的投资方案选优决策方法，即层次──—灰色关联分析法。该方法克服了决策者的主观影响和不必要的计算误差，保护了已有的信息，保证了结论的正确，比模糊综合评判法优越、实用、操作方便。     

斜发沸石岩膨胀可控性的研究

以相应的盐溶液处理嫩江斜发沸石岩，将其改为ＮＨ４＋、Ｋ＋、Ｎａ＋、Ｃａ＋＋及某种混合型，发现在相同的焙烧制度下，每种阳离子型沸石都具有其独特的膨胀率范围，据此，得出斜发沸石岩的膨胀可控性，并提出烧制优质轻骨料的沸石岩化学成分范围。     

基于XML的GIS工程研究与开发

GIS工程在地理信息系统软件的图层管理中起着重要的作用.对于GIS工程的操作,传统的做法是采用INI文件格式或文本格式进行管理,但是这两种方法都有弊端.本文在对GIS工程进行详细研究的基础上,设计出基于MO的工程文件格式,并采用XML技术实现了对GIS工程快速高效的操作.     

In-depth analysis of the fatigue mechanism induced by inclusions for high-strength bearing steels

A numerical study of stress distribution and fatigue behavior in terms of the effect of voids adjacent to inclusions was conducted with finite element modeling simulations under different assumptions.Fatigue mechanisms were also analyzed accordingly.The results showed that the effects of inclusions on fatigue life will distinctly decrease if the mechanical properties are close to those of the steel matrix.For the inclusions,which are tightly bonded with the steel matrix,when the Young’s modulus is larger than that of the steel matrix,the stress will concentrate inside the inclusion;otherwise,the stress will concentrate in the steel matrix.If voids exist on the interface between inclusions and the steel matrix,their effects on the fatigue process differ with their positions relative to the inclusions.The void on one side of an inclusion perpendicular to the fatigue loading direction will aggravate the effect of inclusions on fatigue behavior and lead to a sharp stress concentration.The void on the top of inclusion along the fatigue loading direction will accelerate the debonding between the inclusion and steel matrix.     

带积分边界条件的Poisson方程边值问题解的极限

讨论一类带积分形式边界条件的Poisson方程边值问题解的极限。当区域的内孔收缩为零时，该极限函数就是不带积分形式边界条件的Poisson方程边值问题的解。     

棒线材生产新工艺分析

对近年来国内生产出现的棒线材生产新工艺进行了分析。围绕着无头轧制，热送热装，感应加热、低温轧制, 棒材表面淬火及自回火，轧后控冷等技术的发展现状，作用机理和应用效果展开讨论，并提出了亟待解决的问题。这些工艺技术不但适用于新建厂，而且也适应于已有轧钢厂的技术改造。     

非线性过程求最大熵谱定阶的一个经验表述

由非线性短时间序列的模拟数据对求最大熵谱的取阶区间进行了归纳及用数学表达式吻合，从而得到一个在求最大熵谱时定阶的经验公式，并将若干重大天文事件求最大熵谱时，所使用的阶数或阶数范围与本公式估计比较，其结果基本一致。此公式尤其适用于非线性过程中，从１￣４倍周期内的短时间数据序列求最大熵谱。     

夏商妇女社会地位研究

随着私有制的确立,夏商时期妇女虽失去了女权地位,但在家庭中有一定的权利和地位,特别是商代贵族妇女在经济、政治、军事、文化教育中都享有较高地位.
