温度对电缆终端界面应力影响的仿真研究

open access: yesGaoya dianqi
电缆终端硅橡胶(SR)绝缘与电缆本体交联聚乙烯(XLPE)绝缘之间良好的界面压力,是保证电缆终端高效安全运行的关键。电缆终端内径处的径向应力为电缆终端与电力电缆间的界面压力,温度的变化导致界面机械应力、界面热应力以及SR绝缘应力松弛特性存在差异,进而影响电缆终端的界面压力。文中采用单变量法研究温度对于界面机械应力、界面热应力以及SR绝缘应力松弛特性的影响,通过实验测得SR以及XLPE试样的线膨胀系数随温度的变化规律,将其分配到三维模型中,利用SR绝缘的超弹性和粘弹性本构模型 ...

表面曲率对边界层的影响与边界层外缘附近的连结问题

open access: yes, 1957
利用一种严格的边界層外缘条件重新计算了不可压縮非粘性流体繞二維曲面的运动,求出曲度对表面剪力与速度剖面的影响。墨菲曾首次研究此題,其结果与本文的結果比較,在質与量上均有出入,因此說明如何准确連結边界層与势流对此类問題的重要性。 結果还表明凸面曲度使表面剪应力較平面的剪应力小,也使边界層內的速度比平面的小。反之,凹面曲度使表面剪应力較平面的大,也使边界層的速度比平面的大。又曲度对表面剪应力的影响小 ...

运行复合绝缘子芯棒-护套界面性能评估

open access: yesDianci bileiqi, 2022
芯棒-护套界面性能是表征复合绝缘子运行状态和老化进程的重要对象之一。为准确评估宁夏地区运行复合绝缘子的芯棒-护套界面性能,对宁夏电网运行6年及以上、35 kV~750 kV的33个厂家批次复合绝缘子进行剖检试验和带护套芯棒水扩散试验,并对水扩散试验结果不同的试品做傅里叶红外光谱分析。结果表明,在密封性能良好的情况下,有23个厂家批次复合绝缘子的芯棒-护套界面粘接性下降、耐水解及耐湿热老化性能下降;相同运行环境下复合绝缘子芯棒-护套界面的老化进程与伞裙表面的老化进程不一致;复合绝缘子芯棒 ...

Dual Modulation of Schottky Barrier Height and Width Enables High‐Performance p‐Type MoTe2 Transistors

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Efficient hole injection at metal‐semiconductor interfaces remains a central challenge for high‐performance p‐type transistors based on two‐dimensional (2D) semiconductors. Although substantial efforts have been devoted to reducing Schottky barrier height through contact engineering, the barrier width is rarely addressed, thereby limiting ...

界面张力引起的流动及界面特征研究

open access: yes, 2009
通过对单层流体浮力-热毛细对流和两层流体 B$\acute{\rm e}$nard-Marangoni对流的实验研究,探讨界面张力梯度引起的自然对流的特征及机理问题。考虑到表面张力是温度的函数,对上面是空气(或其蒸汽)的薄液层,加载水平温度梯度将使得气液表面上表面张力分布不均匀,耦合于地面的重力作用,将会驱动薄层流体形成浮力-热毛细对流运动。液层厚度和温度梯度的改变(引起系统长高比、Bond数、Rayleigh数以及Marangoni数的变化)直接影响到薄层流体的对流模式的变化,还可能使得浮力 ...
