试析公共产品的本质属性

公共产品是公共经济学理论的核心概念,也是一个按照属性来定义的概念.但是,它的两个消费属性:非排他性和非竞争性,并没能全面把握公共产品的本质.从而使得公共经济学在运用这个概念进行分析时,存在不少矛盾和模糊之处.本文对公共产品的本质属性进行了较全面的分析,重点强调了不可逃避性和非排除性.

Effects of Second-Order Difference-Frequency Wave Forces on Floating Wind Turbine Under Survival Condition

In this paper, the effects of second-order difference-frequency wave forces on the global motion of an offshore wind turbine system with a large displacement under the survival condition are studied. In this case, the hydrodynamic force is the main force because the blades are feathered to reduce the lifting force. The first-order hydrodynamic forces are calculated by WADAM, while the second-order wave forces are calculated by a customized MATLAB module. Then the hydrodynamic coefficients are transferred to the wind turbine analytical code FAST. Through the comparisons of dynamic responses between the first- and second-order numerical models, it is found that the second-order wave forces significantly influence the motion of floating wind turbine under the survival condition. Moreover, neglecting the second-order force significantly underestimates the tension forces in the mooring lines.     

例谈高考题与新课程理念

2006年的江苏高考试卷,是近年来一份不可多得的好卷。它既延续了近几年考试的稳定性,又与正在进行的高中新课改相衔接,为今后的新课改如何体现考试功能提供了范例,下面以2006年江苏高考题为例。以示说明。题1(10题)我省沙河抽水蓄能电站自2003年投入运行以来,在缓解用电高峰电力紧张方面,取得了良好的社会效益和经济效益。抽水蓄能电站的工作原理是:在用电低谷时(如深夜池)中,,电到站用利电用高电峰网时多,余再电能把水抽到高处蓄水利用蓄水池的水发电。如图1,蓄水池(上游水库)可视为长方体,有效总库容量(可用于发电)为V,蓄水后水位高出下…     

Chelators effect on soil Cu extractability and uptake byElsholtzia splendens

Phytoremediation is emerging as a potential cost-effective solution for remediation of contaminated soils, and bioavailability of metal in the soil for plant uptake is an important factor for successful phytoremediation. This study aimed at investigating the ability of EDTA and citric acid for enhancing soil bioavailability of Cu and phytoremediation by Elsholtzia splendens in two types of soils contaminated with heavy metals [i.e. mined soil from copper mining area (MS), and paddy soil (PS) polluted by copper refining]. The results showed that addition of 2.5 mmol/kg EDTA significantly increased the H₂O extractable Cu concentration from 1.20 to 15.78 mg/kg in MS and from 0.26 to 15.72 mg/kg in PS, and that shoot Cu concentration increased 4-fold and 8-fold as compared to the control. There was no significant difference between the treatment with 5.0 mmol/kg EDTA and that with 2.5 mmol/kg EDTA, probably because that 2.5 mmol/kg EDTA was enough for elevating Cu bioavailability to the maximum level. As compared with the control, citric acid had no marked effect on both soil extractable Cu and shoot Cu concentration or accumulation. The results indicated that EDTA addition can increase the potential and efficiency of Cu phytoextraction byE. splendens in polluted soils.

工程材料与成形加工基础实验远程教育系统的研制

工程材料与成形加工基础实验是机械类专业必修的重要实践性教学环节．由于客观条件的限制，按传统方式进行实验严重影响了实验教学的效率。另外，接受远程教育的学生．无法到学校实验室做具体的实验已经成为影响远程教育教学质量的一个重要因素。而采用本项目研发的远程教育系统，不仅为解决上述问题提供了解决方案，而且对于贫困地区的教学和培训尤具优势。本文结合该系统的开发研制．论述了系统应遵循的开发流程和远程教育系统的开发技术。     

论教学情境的主要类型

传统教学也注重情境创设,新课程从以人为本、回归生活、注重发展的教育理念出发,大大丰富了情境的内涵,并对情境创设提出了新的要求,情境创设因此成为了新课程课堂教学改革的一个热门话题。
