Modeling Dielectric-constant Values of Geologic Materials:An Aid to Ground-penetrating Radar Data Collection and Interpretation
Dielectric-constant Values Geologic Materials Ground-penetrating Radar
2009/10/20
Ground-penetrating radar (GPR) is a near-surface geophysical imaging technique used for non-intrusive subsurface geologic and engineering investigations. Dielectric constant is a critical parameter fo...
超低介电常数介孔氧化硅薄膜的制备及其表征（Synthesis of Mesoporous Thin Silica Films with Ultra Low Dielectric Constant）
TEOS蒸汽 甲基化 介孔氧化硅薄膜 超低介电常数
2010/8/24
研究了以正硅酸乙酯(TEOS)和甲基三乙氧基硅烷(MeSi(OEt)3)为混合硅源，十六烷基三甲基溴化铵(CTAB)为模板剂，采取旋涂技术，在硅晶片表面制备出二氧化硅透明薄膜，再经过正硅酸乙酯(TEOS)蒸汽孔壁强化后采用线性升温焙烧法脱除薄膜孔道内的模板剂，制备出具有超低介电性能的氧化硅薄膜。使用FTIR、XRD和SEM对样品进行了结构表征，并采用阻抗分析仪测量了薄膜的介电常数(k)，纳米硬度计...

In order to simulate the effects of hydrostatic pressure on protein folding/unfolding it is necessary to accurately describe the behavior of the dielectric constant and the density of the solvent (wat...
Effect of the Dielectric Constant on the Double Layer on Clays
Dielectric constant Double layer potential Gouy model Montmorillonite Water
2012/2/2
Electric potentials as a function of distance were calculated for a model of the double layer on clays in which a surface zone a few water molecules thick has a low dielectric constant. This zone is f...
