浅议工程评标方法的科学化

现行的工程项目招标中,不管工程的具体特点,报价在评标方法中均占主导地位。科学的评标方法应当根据工程项目的具体特点合理确定承包商的报价、资质、信誉、业绩、技术标书的先进性及可行性等评价指标在评标方法中所占的权重。从而能够使业主能够通过招标以合理的价格选择合适的工程承包商。     

浅析《婚姻法》的离婚过错损害赔偿制度

《中华人民共和国婚姻法》确立了离婚过错损害赔偿制度，进一步保护了婚姻当事人的合法权益，司法机关对相关案件进行裁决有了法律的依据。但这一制度在实务适用中仍存在不足，需从损害赔偿适用范围、条件、义务主体、请求时效等方面进一步改进和完善。     

从网站中自动挖掘数据记录的算法

为了提高从web中挖掘数据记录的精确性和完整性,提出了同构页与目录页的概念及3个算法.如果一组网页结构相同,只是主信息不同,该网页称为同构页.一个包含有多个指向同构页连接的网页称为目录页.算法1用于发现目录页,它首先将连接排序,并对同一目录的链接记数,如果记数大于某一给定阀值,则对其链接子页进行相似比较并得到结果.同时给出了一个网页相似度判断的函数.算法2采用了噪声信息过滤方法从同构页中挖掘主信息并得到数据记录,该算法是基于在2个同构页中噪声信息相同而只有主信息不同.算法3通过采用Spider技术可以实现从整个网站中自动挖掘数据记录.实验表明所提算法比已有算法可挖掘更完整的数据记录.从同构页中挖掘数据记录是一种有效的方法.

Field measurement of gas permeability of compacted loess used as an earthen final cover for a municipal solid waste landfill

The use of loess as an earthen final cover material is promising in northwest China which has an arid and semi-arid climate. A full-scale testing facility with an area 30 m long by 20 m wide was constructed at the Xi’an landfill of municipal solid wastes to investigate the performance of an inclined capillary barrier cover. The cover consisted of a compacted loess layer underlain by a gravel layer. The testing facility was well instrumented for a gas permeation test and recording of the soil conditions in terms of volumetric water content, pore gas pressure, and soil temperature. Tests were performed to measure the gas permeability of the compacted loess before and after the planting of vegetation on the cover. The field measurements demonstrate that the capillary break at the fine/coarse soil interface allows the upper compacted loess layer to retain more water, and conversely reduces its gas permeability, which is favorable for reducing landfill gas emissions. When the degree of saturation of the compacted loess was greater than 85%, the gas permeability decreased significantly with a further increment in volumetric water content. The growth of vegetation roots tended to fill the large pores in the upper loosely-compacted loess, resulting in a decrease in gas permeability of one order of magnitude. The influence of soil clods in the compacted loess on gas permeability can be one to two orders of magnitude due to an increase in pore size and a decrease in tortuosity.

心功能检查对高血压早期诊断的意义

本文通过检测81例原发性高血压患者和62例临界高血压患者的心功能,结果显示:SV、CO、CI、TPR及AC等指标在两组间差异无显著性(P>0.05),而均与正常对照组有显著差异(P<0.01),说明在血压病理性升高过程中,早期心功能即发生异常变化,并在发展成高血压后的一定时期,心功能保持稳定状态。
