介电常数

The effect of tilting in oxygen octahedra on the dielectric properties is due to the interoctahedral angle increasing to 180℃ consuming the thermal energy, which results in the less effect on polarizability with increasing temperature.

氧八面体扭转能使介电常数温度系数朝正的方向变化的本质是，氧八面体间角吸收热能朝180℃变化，导致纯温度变化对极化率的影响变小。

For the same reason, the Goos-Hanchen shift is negative for both the TE and TM polarization incident waves as the result of the negative pennittivity and negative permeability nature of NIMs served as the rarer medium when total reflection occurring at a PIM-NIM interface.

对于正—负折射率介质界面处发生全反射时的古斯—汉森位移的研究发现当下半空间的光疏介质为介电常数和磁导率均为负的负折射率介质，不管是对于TE波还是TM入射波，在界面发生全反射时古斯—汉森位移均是负的。

According to a known work frequency, the medium thickness and its dielectric constant, the micro-band line width, the sizes of the substrate, the quadrant metallic plate and high resistant surface gap are computed preliminarily then to determine its final sizes by optimizing and emulating utilizing the emulation software of HFSS8.0 edition.

The electrical properties, including surface resistance, volume resistance, breakdown strength and dielectric constant were researched mainly.

Reservoir bed is distinguished by providing the information about resistivity of formations using Electromagnetic Propagated Resistivity Logging method with several mega-hertz operation frequency. The information of dielectric constant of invaded zone is provided using Ultrahigh-frequency Electromagnetic Wave Logging method with above 200 mega-hertz operation frequency, which has no enough radial investigation depth but has a good vertical resolution.

几兆赫兹电磁波传播电阻率测井通过提取地层电阻率的信息来判别油层，以SPPRRYSUN公司源频率为2MHz的EWR-3D测井仪为代表。200 MHz以上的超高频电磁波传播测井具有很高的垂向分辨率，但探测深度太浅，基本上只能反映侵入带介电常数的信息，SCHLUMBERGER公司已推出源频率为1 。1GHz的EPT测井仪。

The simulated temperature field could not only overcome the shortcoming that only one spot temperature can be obtained in the experiments but reduce the experimental times and cost.

Smyth，Merchant和Pincombe提出用压缩坐标法来求解扰动方程[3，4]，在此方法中，电导率、介电常数、磁导率这几个参数都被假定为随温度变化是缓慢的，温度是依赖于功率来变化的。

To further study this problem, the optical axis is rotated by an arbitrary angle. A striking phenomenon is discovered that the Brewster angle is always equal to the rotation angle. This is because the waves in the direction perpendicular to the optical axis become evanescent since the permittivity is positive while the permeability is negative in this direction.

然后进一步的研究了主轴不垂直于界面的情况，发现主轴转动的角度恰好等于此时的Brewster角，这是因为此时垂直于主轴的方向上介电常数为正磁导率为负，只有倏逝波而没有可传播的波存在，因此反射系数为0。

All of the three dielectrics are thermally stable up to 500oC (in N2 ambient for 30 min).

在500oC以上温度的高温退火后，则由於水气的热脱附，使介电常数有所下降。

In contrary to the conventional high-k dielectrics, the AlN film has a very low dielectric leakage and hydrophobic.

不同於传统的高介电常数的材料，氮化铝拥有低的闸极漏电以及高的疏水性。

In this MS thesis, we employed the molecular beam epitaxy method to deposit amorphous HfO2 dielectrics ?

本实验室使用分子束磊晶的方法在矽晶片上成长HfO2高介电常数？

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
