Study of Wallerstein's Capital Accumulation Theory

世界体系的动因是什么？这是世界体系学者首先必须回答的问题。世界体系论的奠基人伊曼纽尔·沃勒斯坦认为，无止境的资本积累是资本主义生产,也是世界体系发展的根本驱动力。在沃勒斯坦之后,其他世界体系学者,如萨米尔·阿明、贡德·弗兰克等人也都坚持这一理论前提,将资本积累视为世界体系的核心问题。对沃勒斯坦资本积累问题的探讨有助于我们理解沃勒斯坦的现代世界体系理论，了解20世纪后半期西方马克思主义者对资本主义历史进程的关注和解读，分析当前的国际形势。 本文旨在考察沃勒斯坦现代世界体系理论下的资本积累理论。“整体性”和“融合性”是沃勒斯坦资本积累理论的两大特点。“整体性”主要体现在分析方法上的创新，即在现代...What is the motive of modern world-system？This is the first question the world-system scholars must answer.Immanuel Wallerstein ,the founder of world-system theory,says endless capital accumulation is the basic motivation of Capitalist production and development of World-System.After Wallertein,other scholars,such as Samir Amin, Gunder Frank and so on,also hold this premise of the world-system the...学位：经济学硕士院系专业：经济学院经济系_经济思想史学号：1532006115078

Optical System for Asymmetrical Crossed Czerny-Turner Raman Spectrometer with High Luminous Flux

为克服分立式便携拉曼光谱仪光通量低的缺点,设计了一种集拉曼探头光路与分光系统于一体的光学系统。探头光路采用大数值孔径的非球面透镜实现样品的有效激发和信号的高效收集,通过胶合透镜组缩小会聚光路尺寸、消除轴向色差。分光系统基于交叉非对称Czerny-Turner结构,为获得期望的光谱分辨率和光谱范围,建立了分光系统光谱分辨率及光谱范围与交叉非对称Czerny-Turner结构参数的关系。由测得的汞灯谱图可知,分光系统的光谱分辨率优于6 cm~(-1)(0.37 nm),光谱范围为790~950 nm(200~2000 cm~(-1))。将设计的光学系统对CCL4进行测试,实验结果表明在相同积分时间内由这种整体式的光学系统检测到的CCL4光谱谱峰强度是用商业探头通过光纤连接分光系统检测到的近3倍,验证了光学系统设计的合理性。To overcome the low luminous flux in separated portable Raman spectrometer, an optical system embodies the probe of Raman spectrometer and monochromator is designed. An aspherical lens with high numerical aperture is used to obtain the effective excitation of sample and the efficient collection of signal in the optical system of the probe. A cemented lens group is used to minish the size of converging path and eliminate chromatic aberration.The monochromator is based on asymmetrical crossed Czerny-Turner structure. For the purpose of achieving desired spectrum resolution and spectrum range, the relationship between the spectrum resolution and spectrum range of the monochromator and the structural parameters of the asymmetrical crossed Czerny-Turner system is established. According to the tested spectrogram of mercury lamp, the spectrum resolution of the monochromator is better than 6 cm~(-1)(0.37 nm), and spectrum range is 790~950 nm(200~2000 cm~(-1)). A sample of CCL4 is introduced to examine the performance of the optical system, the experimented results demonstrate that the peak intensity of spectrogram of CCL4 measured by this incorporative optical system is almost three times as high as that using a commercial probe couples to the monochromator, which verifies the rationality of the design of the optical system.国家自然科学基金(21503171);; 中央高校基本科研业务费项目(20720150091、20720150094);; 福建省高端装备制造协同创新中心资
