To measure the radiation properties of relativistic diffraction generator （RDG） in Ka-band, a TMon modal excitation model is established, which consists of an overmoded circular waveguide and a coaxial line feeding probe. Using the transverse E-field mode matching and the conservation of complex power technique （CCPT）, we deduce the scattering matrix at coaxial line to coaxial line and coaxial line to circular waveguide junctions. Then using the overall cascaded junction scattering matrix, the numerical results for the reflection coefficient of the coaxial line and the power distribution of TMon multi-modal are presented. The numerical results are in agreement with HFSS simulation results and experimental results. The analysis shows that by choosing the appropriate position of coaxial line probe, the power proportion of the device operating mode excited in circular waveguide could be the largest.

为了提高冷链物流的运输效率,解决越库在冷链物流中的应用问题,提出了基于拉格朗日松弛算法的冷链物流的越库调度方法.首先进行了问题域的描述并做出了具体假设,基于问题域以最小化卡车等待时间和越库内部运输成本为目标,建立越库调度的整数规划数学模型.然后,提出了针对越库调度模型的拉格朗日松弛算法,松弛复杂约束后根据决策变量将松弛问题分解为若干子问题,采用次梯度算法求解松弛模型.最后,对各种不同规模的越库模型进行仿真实验,并与传统的贪婪算法进行对比,结果表明,所提出的调度算法适用于问题的求解,并可以在较短时间内获得良好的近优解.

本文将目前海外存在的教授华文的教学形式大体区分为华文教学和汉语教学两个方面,4个层次,并以此为基础分别讨论了各种形式的华文教学的质量及其控制问题。从有限的实地考察、访谈、邮件咨询和文献研究可知,海外华文教学在规模逐步扩大、层次逐步提升和质量逐步提高的同时,也存在着局部质量不高、适用的质量标准欠缺、质量控制亟需加强的问题。文章对海外华文教学中存在的质量及其控制问题进行了分类举例式主观评估,并从宏观方面提出了一些加强质量控制的对策建议。

利用特制的电弧放电装置,研究了水或液氮中碳电弧放电形成炭纳米材料的机理。借助高分辨率透射电子显微镜对电弧放电生成的产物进行了观察和分析。结果表明:在水或液氮中碳电弧放电可以生成多壁碳纳米管和碳纳米洋葱结构,液氮中碳电弧放电可以生成单壁碳纳米角,水中钴催化碳电弧放电可以生成碳包裹的纳米钴颗粒。横向低频交变磁场会影响碳纳米材料的形核过程,并且可以推测磁场交变的频率5Hz与纳米管、纳米洋葱等结构的生长周期存在某种拟合。根据实验现象,提出了一种解释液体中碳电弧放电过程纳米材料生成的理论模型。

本文依据组织社会学制度主义、马克思主义和网络范式三大主流范式,结合目前西方组织社会学的主要发展,回顾了中文文献近10年来组织社会学的研究进展,并作了简要述评和展望。文章提出中文文献的组织社会学研究需要在西方文献领域继续深入研究的同时,还需要从本体论上建立一套自身的理论话语。这种理论话语的建立可以从两个方面入手:一是将国家引入组织场域发展并完善国家-组织场域理论;二是兴起和发展严谨的文化范式。本文从理论范式的角度来梳理回顾中文文献的组织研究,旨在推进组织社会学的进一步发展。
