So the Poynting vector and wave vector are antiparallel, consequently, the light is refracted negatively, and also there are many other unusual behaviors in LHM like reverse Cerenkov radiation, contrary Doppler effect etc.

所以近年來有關左手材料的研究受到了廣泛的關注日本强伦姧人妻网站。2002年，科學家們發(fā)現(xiàn)當光波以一定角度入射到在光子晶體界面上時欧美日韩免费精品一，光波在光子晶體中的傳輸也會出現(xiàn)和在左手材料中相同的現(xiàn)象：比如負折射和超透鏡現(xiàn)象99XXOO视频在线永久免费观看。

Such a hypothetical particle (a tachyon, as opposed to the more familiar tardyon, or slower-than-light particle) might emit Cerenkov radiation analogous to the bow wave of a ship, and thus might perhaps be detected.

這樣一個假設的粒子（超光速粒子是相對于較熟悉的次光速粒子，或者是亞光速粒子而言的）可能放出類似于輪船渦流的契倫科夫輻射先峰资源网，因此可能被探測到。

In the experiments,beam bugs were used to detect the beam currents and the beam positions,and the Cerenkov radiation generated by the electron beams interacting with a quartz plate was used to get the information of the beams.

在實驗中wwwwxxxx.公共厕所，電子束流強度和電子柬心運動用電阻環(huán)進行測試一区二区三区精品视频免费播放，而電子束和石英玻璃的相互作用產(chǎn)生的契侖科夫輻射用來給出電子束包絡和發(fā)射度信息。

Methods According to the theory of Cerenkov radiation, different counting medium and condition on 32 P were studied.

方法根據(jù)契倫科夫輻射的原理操日色，對各種有閃爍液和無閃爍液測量介質和測量條件進行對比實驗研究久热综合。

A beam profile diagnostic system of high current, short pulse electron based on Cerenkov radiation is introduced.

Cerenkov radiation：契侖可夫輻射

Tamm(1895-)從理論上解釋這種現(xiàn)象,指出凡帶電的粒子在通過介質的時候如果速度比光快就會發(fā)射光叫做契侖可夫輻射(Cerenkov radiation),(見圖一). 他們?nèi)嗽?958年合得諾貝爾獎,也是俄人第一次得物理獎,晚於印度(1930)日本(1949)和中國(1957).
