约束稀疏脉冲反演在GX气田开发中的应用研究

GX气田北部地区构造、断层特征较为复杂,地质建模较困难,而约束稀疏脉冲反演是一种基于地震道的反演方法,它是在波阻趋势的约束下,用最少的反射系数脉冲达到合成记录与地震道的最佳匹配。该方法对初始模型依赖性较小,中高频部分不受初始模型的影响,其反演结果能忠于实际地震资料,分辨率与地震资料接近,保真度高。以GX气田为例,通过约束稀疏脉冲反演技术对GX气田开展储层预测,其反演结果与实测井曲线吻合较好,能客观反映地质体在横向上的变化特征,该方法适用于储层横向变化快和非均质性较强的少井区块。     

高职院校《模拟电子技术》教材编写探讨

现有的《模拟电子技术》高职高专教材中普遍存在理论偏深、实践应用内容偏少的问题。高职高专教材应以高职教育培养目标为教材建设与改革的方向,以此选择教材内容并优化其结构,通过实践环节培养创新人才,增强学生学习兴趣,培养学生的实际应用能力。     

经济长波理论与网络文化产业发展

创新,是经济发展的本质规定。文化,是衡量世界发展的重要尺度。网络文化产业发展,正是一种创新性的发展。它既同经济周期、长波理论紧密关联,又具有反经济周期的特性,呈现出逆势上扬的特点。当然,网络文化产业的反周期与逆势上扬,并不一定是消费者直接付费的增长,而可能是其间接支出的累积,例如广告投入的力度加大。中国网络文化产业,正进入发展的黄金时期。

Rethinking Money as an Institution of Capitalism and the Theory of Monetary Circulation: What Can Modern Heterodox Economists/Institutionalists Learn from Karl Polanyi?

Modern heterodox theories of money reject the neoclassical conception of money as primarily a medium to facilitate exchange. These heterodox theories of money all have as common starting point an analysis of credit-debt relations in which production is a central feature, with these economies organized along capitalistic design. The Keynesian-Marxian framework describing the process of monetary circulation, traditionally referred to as the theory of the monetary circuit (TMC), perhaps best represents this comprehensive vision. This broad TMC analytical framework is compatible with institutionalist theories of money that also point to the importance of credit-debt relations. The question, however, is whether this more unified heterodox theory of money, which describes sequentially monetary relations under capitalism, can be used to understand pre-capitalistic monetary institutions. By conceptualizing money as a means of payment rather than medium of exchange, Karl Polanyi’s analysis offers social scientists crucial insights to understanding monetary relations in all types of societies in which credit-debt relations have emerged historically.     

倏逝波在一维氧化硅亚微米波导线中传输特性的研究

[HTK]基于光学倏逝波原理的光纤或波导传感器是目前光学传感器领域的重要发展方向之一,而倏逝波在其中的传输特性是决定该类传感器敏感特性的关键因数.利用倏逝场理论分析了直径102～103nm的一维氧化硅亚微米光波导在其直径与外部介质(折射率)变化时倏逝波的穿透深度.实验结果表明,亚微米光波导的传输损耗将随着波导尺寸和外部环境折射率的变化而变化,倏逝波的传输方式非常适用于高灵敏度探测,可应用于光化学传感器和生物化学传感器的设计.     

Feminism’s fourth wave: a research agenda for marketing and consumer research

Abstract

Three waves of feminism each reveal a very different relationship with marketing. This commentary considers these relationships in the light of what is now frequently being hailed as the fourth wave, a resurgence of feminism that is driven by younger women who harness the power of the Internet and social media to challenge gender inequity. The commentary looks at what distinguishes the fourth wave from its predecessors and highlights key areas in marketing and consumer research where feminist perspectives are sorely required.
