In such a medium, the direction of the Poynting vector monochromatic plane wave is antiparallel to that of its phase velocity. Because of that, DNG displays some unusual electromagnetic properties such as backward-wave effect, negative refractive effect, perfect lens and a limit situation, zero index of refraction materials.

在这种材料中，单色均匀平面波的相速方向和坡印亭矢量方向是相反的，因此使双负材料表现出一系列反常的电磁特性如：回波效应、负折射效应、完美透镜效应和一种极限情况即零折射率材料等。

Parikh and Wilczek further refined and extended the thought of Keski-Vakkuri and Kraus, the radiation was explained as a tunneling process crossing the barrier of horizon, and in literatures the method is called Parikh-Wilczek tunneling method. In our paper, we further studied the effect of Hawking radiation of the apparent horizon of the dynamical spacetime, the FRW universe, and the thermodynamics of the apparent horizon of the dynamical black hole modes, the Vaidya black hole and the McVittie black hole.

更为重要的是，近年来联系于视界热力学一些新的性质被发现：Einstein方程在视界上可以作为热力学第一定律的形式出现；在Friedmann-Robertson-Walker宇宙表观视界上，时空动力学方程(Friedmann方程)也可以写成一个所谓的统一热力学第一定律的形式；局域定义的FRW宇宙表观视界，也存在着在Kodama矢量观测者看来的Hawking辐射效应。

The invention is characterised in that the motion vector is computed from mathematical data derived from the synthesised script and defining the apparent motion of the different objects constituting the scene subject of the sequence.

本发明的特征在于该运动矢量是从推导自该合成脚本计算而得，并确定构成该序列的场景主体的不同对象的视在运动。

This research has studied the validity of vector diffraction field series solution and nonparaxial approximate solution.

本课题研究了矢量衍射场的级数解和非傍轴近似解的有效性。

Thus we can experiment study in frequency conversion control system using the arithmetic of speed sensorless vector control based MRAS.

这样就可以把基于MRAS无速度传感器的矢量控制算法用于DSP的变频控制系统中，进行实验研究。

The mechanism of performance enhancement is analyzed based on the electric field and Poynting vector distributions in array.

So the beamforming and the design of vector array are taken more and more attention, and these have become a hot topic in the underwater acoustics research.

矢量水听器成阵技术和阵型设计也受到人们越来越多的重视，成为水声工程领域令人瞩目的研究方向之一。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
