激发

Excitations from localized states to the conduction band account for the absorption edge shift toward lower energies observed in the case of N/TiO_2 with respect to pure TiO_2.Mixture of visible light absorption of nitrogen doping and oxygen defect gave no obvious onset in the whole range between 400 and 800nm were observed of the samples N/TiO_(2-)A and N/TiO_(2-)M.

UV-VIS-DRS分析掺杂N/TiO_2结果表明，N/TiO_2-H和N/TiO_2-T两种催化剂在490nm处有吸收带边，可见光激发途径是掺杂的N以填隙方式形成的杂质能级吸收电子发生的跃迁引起的；而N/TiO_2-A和N/TiO_2-M两种方法得到的N/TiO_2在整个可见光区域内具有可见光吸收，没有显著的可见光吸收带边，其对可见光的激发途径是掺杂N和氧空缺共同作用的结果。

This is a common phenomenon in semiconductors since the photon-excitation rate is the greatest at the absorption edge where the absorption index is fairly low and the dispersion is small.

激发光的主峰在吸收光谱的吸收边缘，这是由于在此条件下吸收指数相对低散射也很小，光子的激发速度最大）。

The results showed that the DF excitation spectrum was obviously similar to the photosynthesis action spectrum; the DF signal changes with the intensity of excitation light source variation behaved as 'photoinhibition' phenomena of photosynthesis; and the DF intensity has an excellent correlation with photosynthesis rate at room temperature.

实验结果表明：延迟荧光激发谱与光合作用谱存在着明显的相似，延迟荧光强度随着激发光源光强的变化表现出类似的光抑制现象，以及在室温条件下延迟荧光强度与光合速率有着很好的相关性。

According to the whole course of investigation, the result of activators was mainly depended on their chemical characteristics.

从激发剂研制的整个过程来看，粉煤灰早期活性的激发效果主要取决于激发剂内在的化学特性。

The maximal excitation wave of atriums and ventricles are 482.58±0.64 nm and 570.10±0.45nm respectively.

确定了激发心房组织的最大激发峰为482.58±0.64 nm，而最大荧光峰为570.10±0.45nm；而心室组织的最大激发峰为485.45±0.12 nm，而最大荧光峰为574.05±0.33 nm。

It is indicated that the Kelvin wave with large amplitude will have more important effect on response pro- cesses as well as the perturbation move eastward.

指出，由于西边界将激发出振幅大的Kelvin波，以及激发出能形成动力边界层结构的Rossby短波，这种结构使来自风应力的能量可在边界附近聚集和维持，并向东传播，表明了热带西太平洋对El Nio事件的形成和发展较热带东太平洋更为重要，因为后者只激发非色散的 Rossby长波。

Monitored at 614 nm, the strongest excitation wavelength located at 395 nm, which matched to the emission light of InGaN chip.

The excitation spectra of red PL indicate that there may be an energy gapof about 2.5-2.7eV in the samples.The excitation of lower energy(＜2.5eV)cannot excite the red emission.In the range of measurement,there are a seriesof quasi-continuous energy levels above the gap.

对样品激发谱的测量揭示出在激光制备的多孔硅的纳晶硅中可能存在一个大约2.5-2.7eV的带隙，低于这个能量值的激发光基本上已不能激发样品的红光发射，而带隙以上在所测的能量范围内则存在一系列准连续的能级。

The hyperfine effects emerging in all spectra of atomic Rydberg states are due to the nuclear effects including hyperfine structure and isotope shifts. The autoionizing Rydberg states converging to 6p〓 and 4f〓 5d6s 〓 [3/2] 〓 limits were investigated by three photon excitation. In the study of the spectra for those converging to 6p〓 limit, the ICE (Isolated-core excitation) model has been proved to be suitable for describing the excitation of the autoionizing Rydberg states with a lowly excited core.
