Dianci bileiqi, 2023 目前国内柔直换流阀全部采用支撑结构型式，支柱绝缘子是支撑结构的核心部件，其力学性能对柔直换流阀整体结构特性影响显著。由一次整体拉挤成型的大直径芯棒和法兰压接而成的复合支柱绝缘子强度高、韧性好，在现有柔直换流阀中广泛应用。对于压接式支柱绝缘子有限元模型的构建大多采用法兰面与芯棒表面直接刚性连接，这使得仿真模型刚度与实际模型偏差过大，模型失真。基于此，本研究提出了一种基于MPC(Multi-Point Constraints,多点约束)的新型压接复合支柱绝缘子有限元简化模型 ...

Study on the Kink Angle of Multiwall Carbon Nanotubes [PDF]
, 2005 自从碳纳米管被发现以来，人们便一直关注这个纳米尺度管的特性。对纳米碳管特性的研究主要在电磁性能、力学性能、热学性能、光学性能、储氢特性和电化学性能等方面。由于碳纳米管具有以上的特性，人们开始探索在实际商业制品中如何应用它们。碳纳米管分为多壁碳纳米管和单壁碳纳米管。碳纳米管的结构多样，实验观察到十二边形的环状多壁碳纳米管，每次碳管弯曲的角度为30度。对碳管弯曲角度的研究，前人提出了两种模型，一种是五边形－七边形对模型，另一种是应用分子动力学模拟的方法。这两种模型仅限于解释单壁碳纳米管的弯曲 ...

Theoretical Studies on Nonlinear Optical Materials and Biological Enzyme Systems [PDF]
, 2009 材料化学和生物化学是近年来化学领域中最具应用前景的两个研究方向，也是计算化学探讨的热点方向。在材料化学中，非线性光学材料是近四十年才发展起来的一种新型材料。从技术领域到研究领域，它的应用都十分广泛，如制成电光开关、实现激光频率的调谐、进行光学信息处理等。本论文前四章即是针对无机和有机非线性光学材料进行计算，并讨论了非线性极化率和体系电子结构之间的关系。在生命活动中，生物酶起着至关重要的作用，和我们的生活也密切相关。但对它们酶催化反应机理的研究，无论在实验测定还是理论计算领域，仍存在着诸多挑战 ...
