光发射

That ashen glow is earthshine – sunlight that's reflected from Earth and back to the moon.

那淡淡的光就是地球的反照——日光从地球发射到月球的光。

EDFA includes a job to be in 980 or 1, the laser pump of 480 accept rice, it can raise the electron higher energy level.

假如领受到的光信号波长在L或C波段，那么在发射与输入光信号雷同波长的光子后，这些电子将降入低能量级。

But internal reflections an the boundaries of active medium can drastically enhance the onset of ASE, particularly if these reflections lead to a close path, i.e., a ray that is reflected upon itself. In the case, we have a strong feedback mechanism and as soon as the gain in the laser medium exceeds the reflection losses parasitic oscillations will set in.

但自发辐射的存在使得放大器工作介质会在信号光到达前开始发射激光，并且工作介质边缘的内反射能显著增大ASE的发射，尤其当这些反射能导致产生封闭路径时更是这样，当激光介质内的增益超过损耗时，就建立起寄生振荡。

After introducing solenoidal focusing near the photocathode, the beam emittance growth is suppressed dramatically.

Visual carbon stars whose mid-infrared spectra are mainly dominated by photospheric continuum and show large excesses at 60um, represent a transition phase which follows an interruption of mass loss from the oxygen-rich phase and begins a new phase of the mass loss of carbon-rich material. Excesses at 60um in these stars are the emission from the residual of oxygen-rich material.

光学碳星的中红外能量主要来自光球，在60μm处存在超量发射，人们认为其演化阶段处在抛射富氧物质终止和新的富碳拱星壳层形成之间，其60μm超量发射就是富氧物质的残余效应。

Diphenyl-5-pyrenyl-2-pyrazoline shows the emission characteristics of pyrene in solution or the emission characteristics of pyrazoline in films and bulk crystals.

但是，DPP超微粒则表现出了分别出自于芘坏386 nm、吡唑啉环465 nm和分子之间的吡唑啉坏-芘环电荷转移激子570 nm的三重发射，而且各自对应各自的激发光谱，即三重发射的光通道互不干涉。

Invoked. Once per day between dawn and dusk the Dawnstone can shoot forth rosy spheres of fire equal to a wizardly meteor storm that travel up to one mile distant at the bidding of the priest of Lathander touching it. Once per turn the Dawnstone can shoot two rosy-hued rays up to 100 yards distant; each is equal in effect to a flame strike. These rays can be guided and bent by a priest of Lathander touching the stone to strike at desired targets (who must be visible to the summoner) but they can also deliberately or inadvertently intercepted by other living beings. They stop as soon as they strike a living creature.

触发：每天一次从黎明到黄昏的这段时间内在洛山达的牧师接触它并发出命令之后黎明之石能对一英里之内的目标发射四枚明亮的光球效果等同法术&流星爆&；每回合黎明之石可以对100码之内发射两道灿烂的光束效果等同于焰击术；任何接触黎明之石的洛山达牧师可以依意愿对这些光束定位或转向以攻击特定的目标但这些光线也会有意无意的被其他生物所阻挡它们会在接触到任何生物时被阻挡住。

The results show that photocatalyst TiO2 improves the removal rate of toluene in not only the nitrogen plasma field (NTP-P-O2/N2) eradiating ultraviolet light but also the argon plasma field eradiating visible light. This supports the idea that both the UV light and the high-energy electron in the plasma field can activate TiO2. Furthermore, the toluene removal rate in NTP-P-Ar system is 5% higher than that in NTP-P-O2/N2 system, confirming that high-energy electron has greater effect on the degradation performance of toluene, as compared with UV light.

结果表明：在发射紫外光的氮等离子体场(NTP-P-O2/N2)中和发射可见光的氩等离子体场中，TiO2：均能提高体系的甲苯去除率，说明等离子体场中产生的紫外光和高能电子均能激活光催化剂TiO2；NTP-P-Ar体系中的甲苯去除率较NTP-P-O2/N2：体系中的约提高5%，说明等离子体场中高能粒子对甲苯降解性能的影响要强于紫外光的影响。

Luminous intensity is the intensity in a given direction of visible light.

可见光在某一特定方向内所发射的强度就是光强 I，一般来讲，光线都是向不同方向发射的，并且强度各异。
