二重开放、产业集聚与区域协调

浙江大学学报(人文社会科学版) , 2010,
Abstract: ?一国提高对外开放水平和对内开放水平具有不同效应:提高对外开放水平,则该国内部地区间产业规模的差距先扩大后缩小,故较低或较高的对外开放水平都有利于地区间平衡发展;提高对内开放水平,则该国的产业规模始终增加,但地区间的差距不断扩大。从福利角度看,如果一国逐步提高对外开放水平,则该国内部不同地区消费者的福利变化方向是一致的,都呈现出先增大后减小的趋势,而外国消费者的福利水平则不断提高;如果一国逐步提高对内开放水平,则该国内部不同地区消费者的福利始终增大,而外国消费者的福利不断减小。

浙江大学学报(人文社会科学版) , 2010,
Abstract: International integration and regional integration have different effects on a country . Increased international integration initially enlarges regional gap in terms of industrial size , but then narrows it , which means that any level of international integration benefits balanced development between regions .By contrast ,increased regional integration attracts more economic activities to that country , but leads to larger regional gap . In terms of welfare effects , when a country gradually increases its international integration ,the welfare level of its consumers firstly rises ,but then drops , while foreign consumers'welfare level is always on the rise . When a country upgrades regional integration , its own consumers'welfare always increases , while the opposite is true for foreign consumers .
创新教学理念改革教学过程实施创新教育——简介“五U三T创新教学法”
Innovative Ideas of Teaching Reform of Teaching Process Implementation Innovation Education—“Five U Three T Innovation Teaching Methodology” Introduction
 [PDF]


Advances in Education (AE) , 2011, DOI: 10.12677/ae.2011.13025
Abstract:

本文试图针对传统教学模式的弊端提出一种创新的教学模式——“五U三T创新教学法”。该教学模式力求把“抠文本、扣应用、求感悟、谋创新、促发展”的教育理念、内容、方法与“学生个体自主探究、学习小组合作探究、师生互动拓展探究”的教学流程和环节结合起来,实现教学理念、教学内容、教学方法与教学流程、教学环节的有机结合和高度统一。
This paper tries to against the drawbacks of the traditional teaching mode is proposed innovative teaching mode—“five U three T innovation teaching method”. The teaching mode of “aims to dig text, buckle application, beg comprehension, seek innovation and promote the development of education concept, content, method and the” individual student explore independently, study group cooperative exploration, teacher-stu-dent interaction expand inquiry “teaching process and links combine, realize the teaching concepts, teaching contents, teaching methods and teaching process, the teaching link organically combined and high unification.

Method of Ranking Medical Journals of CSTPCD and Scoring Method for Evaluating Papers and Citation Quality
医学期刊的层次划分及评估论文、引文质量的赋分方法

李众,孙瑞,亚明,王若涛
中国科技期刊研究 , 2003,
Abstract: 本文应用布拉德福区域分析法对国内医学期刊进行层次划分,并依据各层次期刊的影响因子(IF)均值对分布于相应层次的论文和引文赋予不同的分值,指出所划分的各层次医学期刊IF的分布基本符合布拉德福定律中的离散现象。认为所进行的层次划分和赋分方法可应用于对期刊所载论文及引文质量进行评估。

中国沙漠 , 2006,
Abstract: Based on the fractal theory,the spatial fractal character of China desertification land has been quantitatively analyzed in this paper.Some conclusions are drawn as the followings.(1) The relationships between size and frequency of patch area and patch shape index objectively exist for China desertification land.(2) The relationships between perimeter and area of patches objectively exist for different types of China desertification land,which shows that the spatial fractal structure exists for China desertification land.(3) Fractal dimensions of different types of China desertification land are calculated.Fractal dimension of Latent wind-drift sandy land is the largest with value 1.5148,while smallest for Shifting dune with value 1.2422,reflecting the most complex for Latent wind-drift sandy land and the simplest for Shifting dune in spatial structure.(4) The complexity of spatial structure of different types of China desertification land is listed in this paper.(5) Stability indexes of spatial structure of different types of China desertification land are calculated and listed too.Stability index of Shifting dune is the largest with value 0.2578,while smallest for Latent wind-drift sandy land with value 0.0148,showing the spatial structure of Shifting dune is the steadiest,while the most unstable for Latent wind-drift sandy land.(6) The special attention should be paid to the ecological protection and restoration to prevent Latent wind-drift sandy land and Latent desertification land from further degradation now.

麦类作物学报 , 2011, DOI: 10.7606/j.issn.1009-1041.2011.01.016
Abstract: 为了研究不同春小麦品种年际间碳同位素分辨率(Δ)的稳定性及其与叶绿素含量的关系,选择不同生态区的小麦品种,分析不同年份不同品种Δ及不同部位Δ的差异,并分析了Δ与叶绿素含量的关系。结果表明,不同年份同一品种的Δ差异很小,稳定性好,同一年份不同品种的Δ差异较大,旱地小麦品种的Δ低于水地小麦品种。同一品种不同部位Δ存在较大差异,叶片Δ与茎秆Δ很接近,且高于籽粒Δ。不同品种的叶绿素含量差异较大,旱地小麦品种的叶绿素含量低于水地小麦品种,Δ与叶绿素含量呈极显著正相关。
计及运行风险的多目标发电优化调度

中国电机工程学报 , 2012,
Abstract: 针对电网运行中面临的不确定因素以及传统确定性安全准则的缺点,将风险理论引入到发电优化调度中。从支路过载和节点电压越限的角度定义运行风险指标,采用效用函数度量故障后果以反映不同故障间的相对严重程度。构建基于风险的多目标经济调度(risk-basedmulti-objectiveeconomicdispatch,RBMOED)模型,该模型以同时降低系统运行风险和机组燃料成本为目标函数,并满足基态下的安全约束条件。为求解RBMOED模型,首先应用改进多目标差分进化算法获取运行风险和经济性之间的权衡关系,进而根据电网运行的协调性准则辅助调度人员进行决策。对IEEERTS-79测试系统进行计算分析,结果表明,所提发电调度方法能给出全面的关于系统风险水平的量化信息,并且可辨识出电网中的薄弱环节。
