吉赫兹横电磁波传输室内导体侧边形状的研究

GTEMCell可以用较小的输入功率在内部建立均匀的电磁场 ,是理想的电磁兼容测试设备。为便于加工 ,以往的GTEMCell过渡接头中的斧形过渡块均采用近似设计 ,即在其宽度方向上采取直线过渡。这样做的结果是特性阻抗在GTEMCell过渡段的分布不理想 ,与标称值50Ω相差较大 ,妨碍了GTEMCell内行波状态的建议 ,降低了GTEMCell应有的良好性能。为对其进行修正 ,该文首次给出了精确的斧形过渡块侧边的连续曲线方程 ,对连续曲线方程进行了求解 ,并对曲线进行了描绘和比较。

复合材料成形过程中模具-构件作用的一种表征方法

利用光纤Bragg(布拉格)光栅(fiber Bragg grating,FBG)传感器,结合理论模型,对碳纤维复合材料(CFRP)热压罐成形过程中模具-构件间的作用力进行了研究.结果表明,在模具表面涂覆脱模腊的条件下,模具与构件界面间不仅存在滑动摩擦力,还会发生粘接作用.固化完成后,温度下降使模具与构件产生不同程度的变形,导致粘接力上升,达到极限值时发生脱粘现象.脱粘首先发生在边缘,沿模具长度方向向中心移动.模具与构件热膨胀系数的差异是摩擦力产生和构件发生变形的主要原因.     

Improvement of image sticking on liquid crystal displays with polymer layers produced from mixed monomers

As a model of polymer-sustained-alignment liquid crystal display (PSA-LCD), the LC cells having the polymer layers produced from the homopolymers and copolymers of 4,4?-dimethacryloyl-oxy-biphenyl (4,4?-DMABiph) and 2,6-dimethacryloyl-oxy-naphthalene (2,6-DMANaph) were prepared and investigated image sticking phenomenon with evaluations of residual direct current voltage (V_rDC) and difference in pre-tilt angle before and after application of alternate current (AC) voltage (Δtilt). The V_rDC was effectively improved by adding a small amount of 2,6-DMANaph to 4,4?-DMABiph because the concentrations of radicals and ions in the LC layer were decreased due to increase in the rate constant of the polymerisation with the addition of 2,6-DMANaph under UV light exposure. The Δtilt was proportionally increased with increasing the weight ratio of 2,6-DMANaph in the mixed monomers of 4,4?-DMABiph and 2,6-DMANaph. We confirmed that the range of the weight ratio for 2,6-DMANaph in the mixed monomers of 4,4?-DMABiph and 2,6-DMANaph from 10 to 25 wt% was useful for obtaining the small level of image sticking in the PSA-LCD.     

肖邦《^bD大调（雨滴）前奏曲》形态分析

肖邦《^bD大调（雨滴）前奏曲》在肖邦的钢琴作品中,虽说仅仅作为小型、亲切的钢琴小品（肖邦的前奏曲、夜曲、圆舞曲被称之为第二类作品）出现,但它自身在乐谱文本中蕴藏的种种音乐要素,以及在这些作曲技术之下承载的音乐情感和创作理念,却为肖邦的第二类钢琴作品同样赋予了钢琴诗歌的美誉。     

A simple method for simulating viscoelastic fluid flows in slit channel

A low-cost semi-analysis finite element technique, named the finite piece method (FPM) is presented in this article. It aims to solve three-dimensional (3D) viscoelastic slit flows. The viscoelastic stress of the fluid is modelled using an K-BKZ integral constitutive equation of the Wagner type. Picard iteration is used to solve non-linear equations. The FPM is tested on flow problems in both planar and contraction channels. The accuracy of the method is assessed by comparing flow distributions and pressure with results obtained by 3D finite element method (FEM). It shows that the solution accuracy is excellent and a substantial amount of computing time and memory requirement can be saved.
