协商理论简介

本文对协商问题的研究,特别对其与经济理论的联系作了一个简要的说明,重点按照公理形式探讨了协商理论的发展及其成果,并对协商问题在多人情形下的推广和关于协商问题风险性分析等都作了一些介绍。本文还对策略形式探索协商理论的主要发展“轮廓”作了描述。对有关协商理论各分支的研究现状和动态亦作了些评述。     

区域资源空间分配的数学原理

文章根据经济学的择扰分配原理和区域经济地理学的区划思想，提出资源在地域空间上合理配置的数学规划方法，并指出了应用此方法的有关问题及解决办法。在探讨方法论的同时，文章也得出如下结论：资源的空间分配法则不是域均衡，而是边际收益的空间统一。     

浅析变换思想在平面几何教学中的渗透

数学教育改革历程中,几何学课程受到变换几何思想越来越大的影响。变换使得几何学由静态转向动态,能使学生加深对图形的理解,培养几何直觉。     

Illustrations with Real Examples of Using Ecological Regulation Strategies Against Crop Pests in China

In this paper, a series of examples from China, including those using ecological regulation strategies successfully to keep crop pests under control and those making more damages of crop pests caused by wrong cropping systems, crop distributions or extensive cultivation, were given and analyzed. From these, two pieces of experience were enlightened as follows： the first, the refoms of cropping systems and crop distributions must be beneficial to pest control or at least not increase the damage of crop pests; the second, we should further clarify the relationship between population dynamics of pests and cropping system/crop distribution, the basis for correctly laying down the ecological regulation systems.     

Bernoulli数模2r和3r的同余式

设{Bn}为Bernoulli数,m、n为自然数,本文证明了同余式(2-22n)B2n≡1-4n ∑mk=1(2n)/(2k)24kB2k (mod 24m 3)与(3-32n)B2n≡2-6n 2∑mk=1(2n)/(2k)32kB2k (mod 32m 1).取m=1,2,得到[5]中宣布的(2-22n)B2n(mod 27)与(3-32n)B2n(mod 35)的简单同余式.     

弱Hopf代数wslq2的代数结构

将弱Hopf代数的一个特例弱量子群wslq2分解为％（sl2）和二元多项式代数的直和，从而将wsl12的表示归结为％（sl2）和二元多项式代数的表示。还研究了wslq2的限制表示，证明了wslq2（m，n）同构于Uq（m，n）和一个带关系的二元多项式代数的直和，从而将wslq2的限制表示归结为％（sl2）和一个带关系的二元多项式代数的表示。     

金属在福州地热水中的腐蚀热力学研究──(I)、铜—地热水系统

作者从热力学角度以电位－ｐＨ图探讨金属在福州地热水中的腐蚀趋势．本文报导铜－地热水系统，采用ＢＡＳＩＣ语言编制程序在ＡＰＰＬＥ－Ⅱ微机上计算高温热力学数据，并以ＤＸＹ－８００绘图仪绘制电位－ｐＨ图．同时，测定了铜在福州Ｇｗ２井地热水中的实际腐蚀电位．结果表明：在此地热水中，当温度低于３１８Ｋ，铜表面生成Ｃｕ２Ｏ膜，高于３１８Ｋ，生成ＣｕＯ膜，二者都位于钝化区．     

Functional magnetic resonance imaging of amphetamine craving

The aim of this study is to identify the brain activity associated with amphetamine craving for understanding the neurobiology of addiction by watching pictures of happy, sad or amphetamine. Brain activity was measured in 12 amphetamine addicts and 12 healthy subjects by fMRI while the subjects watched pictures designed to elicit happy feelings, sad feelings, or the desire to use amphetamine. The result demonstrated that amphetamine cues led to abnormally high cingulate and low frontal lobe activation in amphetamine addicts, who showed abnormalities in affect-related brain activation.     

An ERP study for the degrees of the difficulty in visual search

The present study mainly probed the relationships between ERP components and the degrees of difficulty in visual search. Three experimental and one controlled conditions were randomly selected. Results showed that the P1, N1, and P2 amplitudes and latencies had no significant differences among the three experimental and one controlled conditions, and the ERP waveforms of low perceptual load of visual search were different from that of high perceptual load. These results might indicate that the latencies and amplitudes of initial P1, N1 and P2 in high and low perceptual load conditions were almost the same. The ERP waveforms of parallel search were very different from that of serial search, and the ERP waveforms of serial search were very similar. The P3 amplitudes increased as the degrees of the difficulty in visual search decreased.     

《红字》译本对象征、比喻手法的移植比较

名著《红字》迄今为止已有10多个译本出现,且不同时代有不同译本,说明其复译的必要性和可行性。《红字》中大量运用了象征、比喻手法,不仅对烘托主题、刻画人物起到了举足轻重的作用,而且具有含而不露,耐人寻味的修辞效果。通过对3个译本进行比较,旨在探讨译本在移植原著象征、比喻手法上的成败得失,为后人复译提供借鉴。
