查询词典 photons

Confronting the run of RHIC, the study about the signals of deconfinement and partial restoration phase transitions under extreme environment is the hot topic in high energy circles. In particular, because the FM signals: dileptons and photons can pene- trate the medium almost undisturbed and are considered to be the clearest ones, have drawn much attention.

随着相对论重离子对撞机RHIC的开通运行，关于高温高密极端条件下退禁闭相变和手征对称部分恢复的相变信号的研究是当今高能核物理界的重大热点。

A stream of such photons, used for their penetrating power in radiography,radiology,radiotherapy,and scientific research.

X射线一束X光射线，可利用其穿透能力，应用到放射线照相术、放射学和放射疗法以及科学研究方面。

X-ray is a stream of such photons, used for their penetrating power in radiography, radiology, radiotherapy, and scientific research.

X光照片是X射线一束X光射线，可利用其穿透能力，应用到放射线照相术、放射学和放射疗法以及科学研究方面。

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. So LW white LED radiation power output has to consume 1.51 W electric powers and the luminous flux efficiency limitation of electrical to optical conversion for the white LED is 197.8lm/W at above condition.

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1W的光功率所需的电功率为1.51W，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197.8lm/W。

We will begin with light harvesting and follow photons to the sites of primary photochemistry: the photoreaction centers.

我们将从光的捕获开始，跟随光子来到原初光化学反应的位点：光反应中心。

EGS4, a Monte Carlo code, was used to simulate the transportation of electron photon clusters in the targets and the photon track lengthes were calculated by tracking the radiation photons to determine the photoneutron yields .

计算了电子加速器中不同能量的电子垂直入射到钨靶和金靶上时的光中子产额。

Two photons are created in the decay of the neutral pion.

双光子是在中性兀介子衰变中产生的。

Grosskopf himself believes that photons "pulsate" in the direction of light.

他相信光子循光的方向做有规律跳动。

This energy is transmitted through space in the form of bundles or concentrations of energy known as quanta or photons.

这种能量是以能束或能流的形式，通过空间传递的。

For light, the quanta have the wave length of the masked photons

对光来说，光量子的波长是掩蔽光子的波长。

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".
