The extra electron fills up the lower-energy state in the conduction band, causing excited electrons to, effectively, spill over into the higher-energy, photon-emitting state.
这个额外的电子填充了传导带的较低能级，有效的导致了被激发的电子溢入较高，释放光子的能级。
Let's grasp the opportunities to link agriculture with the transition to lower carbon-emitting, climate resilient growth.
让我们抓住机会把农业与向低碳排放、气候弹性增长联系起来。
The least-cost option to lower the risk is to start now and steadily transform the global energy system over the coming decades to low or zero greenhouse gas-emitting technologies.
降低风险的最小开销方案就是现在启动政策并且在未来数十年内逐步将现在全球能量系统转变为低温室气体排放或零排放的技术。
The second strategy was to lower the energy difference between the two conduction-band states so that excited electrons would be more likely to spill over into the photon-emitting state.
第二步策略是减小两个传导带态的能量落差，这样一来受激发电子就更容易溢入光子释放态。
The pump light from the light emitting device 102 will excite the wavelength converting element 110 and light with lower energy will be produced.
来自发光装置102的泵浦光将激发波长转换元件110并且将产生具有较低能量的光。
When burned, waste oil biodiesel is also generally cleaner for the air than diesel, emitting lower levels of pollutants, including particulate matter.
废油制成的生物柴油燃烧后造成的空气污染通常也比柴油要小，包括颗粒物在内的污染物的排放量更少。
