查询词典 photons

Atom, molecule or radical can be excited to a specific intermediate state by absorbing m laser photons, then the parent ion can be produced by absorption of another n laser photons. The ion yield can be increased drastically due to resonant absorption, comparing with the ion yield in non-resonant absorption. This multiphoton process is usully called Resonance Enhanced Multiphoton Ionization. REMPI technique plays an important role in detecting the high electronic excited states of atoms, molecules and radicals.

原子、分子、离子或自由基在同时吸收m个光子从下态共振跃迁到中间态后再吸收n个光子使其电离的过程中，下态和中间态的多光子共振吸收使得产生的离子信号强度比相应的非共振多光子电离得到的离子信号强度有很大的增强，该过程称为共振增强多光子电离REMPI。

Therefore there exist the so called vacuum fluctuations. In the QED, for example, there exist the effects of zero-point oscillations of photons, the effects of vacuum polarization of electron-positron paris, and so on. They all could result in observable consequences , such as the anomalous magnetic moment of the electron, the spontaneous emission of atoms in excited states, the Lamb shift and the Casimir effect, which have been verfied in experiments.

例如，在量子电动力学中真空中存在着光子的真空零点振动效应，正负电子对的真空极化效应等等，它们都导致可观测的物理效果，如磁矩反常、激发态原子自发辐射、兰姆移动、卡西米尔效应等。

To analyse the signal test, binomial probability law was used for significance testing of signals in the images emitted from human hand in different period of time, which proved that human hand can emit ultra-weak bioluminscence, the photon inensity emitted from fingers is in the range of 300～550 photons/s and the whole hand in 850～1200 photons/s.

The result showed that the luminous flux for LW white LED radiation power output is 298.7 lm and the total photons are 2.7×1018. If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons.

在理想情况下，注入一个电子-孔穴对产生一个蓝光光子，设荧光粉的量子效率为1，因此，注入的电子-孔穴对数亦等于白光光子数，进而计算出白光LED每辐射1 W的光功率所需的电功率为1.51 W，上述白光LED发光光谱对应的白光LED的电-光转换的理论极限流明效率为197.8 lm/W。

Hello, hair removal is recommended that you go to a regular hospital for plastic shed, for hair removal methods currently being used for hair removal using photons, the photons unhairing this unique light and heat treatment technology, full use of the combined effect of light and heat, through the launch special spectrum of pulsed light, penetrate the skin to reach the depth of different organizations, was the corresponding depth of the hair follicle, hair dry, and melanoma cells, such as target tissue absorption of heat generated by the formation of an instant local high temperature, dry and damage hair follicles, and obstructed and the termination of hair growth, to achieve permanent hair removal results.

您好，脱毛建议您去正规的整形医院进行脱毛，对于脱毛目前采用的方法是采用光子进行脱毛的，光子脱毛这种独特的光热治疗技术，充分利用了光和热的综合效应，通过发射特殊谱段的脉冲光，穿透皮肤到达不同的组织深度，被相应深度的毛囊、毛干、黑色素细胞等靶组织吸收，产生的热量形成瞬间局部高温，破坏毛干及毛囊，阻碍和终止毛发的生长，达到永久性脱毛的效果。

That means everything we picked up is the result that we release photons to the environment or draw on photons from it continuously. Because a group of photons are taking in the information of environment, so we may say it's not only photons that the object absorbed from environment, but photons information. After absorbing photons, the object reissues photons carrying its own information to be absorbed by others and perceived one's being.

就是说我们看到的所有物质，都是自己不断与环境作用光子，不断地从环境中吸收光子，由于这一群光子携带有环境的信息，我们说物质从环境中吸收到的不仅仅是光子，而是光子信息；物质吸收之后，再发出携带有自己的光子信息，供其它物质吸收感知我的存在。

Moreover, the first-quantized theory of photons is established, and a quantum-mechanical equation of photons inside a waveguide is presented, these are important for us to study photons locality in three dimensional spaces.
