二溴羟基苯基荧光酮分光光度法测定痕量钴的研究

本文研究了在CTMAB及Cl~-存在的情况下,二溴羟基苯基荧光酮光度法测定痕量钴的方法。在pH=9～11范围内,Co(Ⅱ)与显色剂形成1:5的蓝色配合物,其最大吸收波长位于640nm,表观摩尔吸光系数为1.4×10~5。钴量在0～14μg·50mL~(-1)范围内符合比耳定律。本法应用于猪肝中痕量钴的分析,结果令人满意。     

大学英语教学改革的最新动态研究

随着中国加入WTO,以及北京申奥的成功,社会对外语人才的要求越来越高。大学英语教学虽已取得了一定的成绩,但这些成绩与我国经济发展和改革开放深入的实际之间依然存在着巨大差距,为了满足新形势的需求,大学英语教学改革势在必行。     

从大学英语四、六级考试改革看课堂教学改革

教育部公布的<全国大学英语四、六级考试改革方案>引发了高校对大学英语四、六级考试的反思.同时,各高校更加重视对英语教学方法的改革,使学生在听、说、读、写、译5种基本技能上全面提高.     

"人类纪"新地质时期理论研析之二——地球环境生态系统灾变现象与生态灾变论

人类非理性行为与活动破坏了自然生态系统,导致了地球生态环境的灾难性变化。这种灾变现象表现在飓风海啸、沙尘暴、洪涝等灾害,经常造成生命和财产的损失,成为人们普遍关注的焦点。本文根据灾变现象的规律性变化构建了“生态灾变论”。当今人们在“人类纪”新时期正面临着生态灾变现象的挑战,必需对恶化了的生态环境进行更新强化其功能,同时,我们还必需以综合整体观来创建“生态、经济、社会、环境、文化、景观”六效应协同增长的现代生态文明社会作为时代的使命。     

Do greater amounts of FDI cause higher pollution levels? Evidence from OECD countries

Using an ARDL model for a panel of 15 OECD countries, this work analyses the impact that FDI, both jointly and by sector, has on CO₂ emissions. The findings reveal that these countries are yielding to the pressure on the trade sector. Unexpectedly, gross fixed capital formation shrink pollution, excluding in the mining sector. With findings supporting the Pollution Haven Hypothesis, policymakers must pay attention to FDI inflows, ensuring that FDI place high importance on the transfer of green technologies to improve the efficiency. These goals could be achieved through an increase in the stringency of environmental laws within the host countries, especially the ones related to FDI.     

用VB开发的试题库管理系统

介绍用VISUAL　BASIC开发的C语言试题库管理系统。该实用系统具有良好图形用户界面,操作简单,维护高效,通用性和移植性极强,在应用中取得良好效果。     

A test statistic for weighted runs

A new test statistic based on runs of weighted deviations is introduced. Its use for observations sampled from independent normal distributions is worked out in detail. It supplements the classic χ² test which ignores the ordering of observations and provides additional sensitivity to local deviations from expectations. The exact distribution of the statistic in the non-parametric case is derived and an algorithm to compute p-values is presented. The computational complexity of the algorithm is derived employing a novel identity for integer partitions.

Reforming against all odds: Multi‐pillar pension systems in the Czech Republic and Romania

Attempts to replace pay‐as‐you‐go pension schemes with private funded systems came to a halt in Central and Eastern Europe after 2005. However, more recently, the region has witnessed two belated reformers: the Czech Republic and Romania. Both countries decided to partially privatize pensions despite the rising tide of evidence concerning the challenges associated with the policy. We argue that while part of the domestic political elite remained supportive of private funded pensions, the difficulties experienced by earlier reformers and reduced support from International Financial Institutions led to the adoption of small funded pension pillars. Such cautious attempts at privatization might become more common in the future as large reforms have proven politically unsustainable.
