查询词典 photons

In this thesis, several problems of time-dependent systems in various branches of physics are investigated by making use of the generalized invariant theory and the invariant-related unitary transformation formulation. The problems are given as follows:(1) Spin model and geometric phase factor in the fiber We investigate the fiber experiment performed by Chiao-Tomita and the Chiao-Wu theory concerning the geometric phase factor in the optical fiber, and then show that the investigation of the propagation of photons inside the noncoplanar optical fiber can be regarded as that of a second-quantization spin model.

本论文用推广的不变量理论和与不变量有关的幺正变换方法研究了一些物理分支中的几个含时系统问题：(1)自旋模型与光纤中光子几何相因子问题重新考察了Chiao-Tomita光纤实验和Chiao-Wu关于光纤中光子几何相因子的理论，证明了在非共面弯曲光纤中传播的光子运动问题实际上可以化为二次量子化含时自旋模型研究。

In a fluid moving nonuniformly, however, the phonons' velocity is altered and their wavelength can become stretched, just like photons in a curved spacetime.

然而，在流动不均匀的流体中，声子的速度会改变，而且它们的波长也会拉长，正如同弯曲空间中的光子一般。

In the present work we have studied theses two complementary methods to identify photons in the electromagnetic spectrometer PHOS.

通常有两种方法来鉴别光子和其他粒子：之一，在PHOS前放置一带电料子反符合探测器CPV。

Photons and photoactive room temperature ionic liquid cations replaced conventional oxidants and metal complexes to promote the polymerization of aniline monomer.

在聚合反应过程中，光子和具有光化学活性的室温离子液体阳离子取代了传统的化学氧化剂和金属络合物促使苯胺单体发生氧化。

We have obtained illuminate illuminate image of a single Photobacterium phosphoreum which shows that its size is about 2.4×0.62 and the illuminate intensity is in the order of 100 photons persecond.

应用此系统拍摄到了单个明亮发光杆菌的发光图像，图像显示明亮发光杆菌的大小为2.4×0.602，单个细菌的发光强度在100光子／秒量级。

Therefore, there're only single charged parent ions of the sample gas molecule under the condition of photons' irradiation effect, and no fragment ions produced. Consequently, the mass spectra obtained from photoionization is very simple, and the sample gas can be detected without preseparation.

样品气体分子在光子的照射作用下只产生单电荷母离子，不产生碎片离子，以该电离方式获得的质谱图非常简单，因此气体样品不需分离即可进行检测。

In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).

1966年，肯尼思·格雷森、瓦迪姆·库兹民与乔奇·扎采品表示，充有高能量的粒子（大多数太空射线都属于原子核，因此也就具有正电）应该会由于太空微波背景下（渗透到整个宇宙的大碰撞所遗留下的辐射）的光子碰撞而减慢速度。

But a traditional repeater destroys the quantum states of the photons, such as their planes of polarisation.

然而传统的中继器会破坏光子的量子形态，正如时他们的水平面发生偏振。

The reality in question—admittedly rather a small part of the universe—was the polarisation of pairs of photons, the particles of which light is made.

这里我们讨论的实在——必须承认，这是世界的一小部分——是许多组光子[2]的极化。

Sweet photons,I do not know if you are waves or partides,but you go down smooth.

多好的阳光！不管是波还是粒子，照在身上总是那么柔和。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
