跃迁能

The relationship of optical gain with well width, lnAs composition and the carrier concentration is obtained by considering the energy band of the strain material, transition matrix, band gap shrinkage due to carrier concentration, and carrier intraband relaxation.

考虑了应变体材料的能带结构、光跃迁矩阵元、载流子浓度引起的禁带变窄以及载流子带内驰豫效应后，模拟得到了GaAs／InGaAs／GaAs应变量子阱光增益与阱宽，InAs给份及注入载流子浓度的关系。

According to the partial research work of a project supported by the NSFC, this paper made an investigation in detail on the dynamics, the performance and the cataphoresis effect of Ca+ recombination laser excited by high repetition rate pulsed discharge.

高频脉冲电泳式He-Ca+复合激光与传统的He-Ca+复合激光相比，具有避免阻挡光路、能够相对独立控制钙蒸气压强、维持长期稳定放电和较长寿命的特点，能同时输出几百毫瓦功率的近红外RM跃迁激光和近紫外的复合激光，在微电子技术、激光治疗和可调激光器泵浦源等方面具有广泛的应用前景。

This behavior is suggested to be originated from delocalization of the localized carriers by thermal activation.

由变温光激萤光光谱，观察到随温度增加能量峰值有下降、上升再下降的现象，此S型行为是因为载子受到温度的活化，脱离原本的局域态而跃迁到高能量能态。

The results show that, after treated with microwave radiation, the surface free energy of the powder is enhanced from 39.6mJm^(-2) to 41.8mJm^(-2), This is mainly caused by the rearrangement of electric charges on the grain crystal surface, and this phenomenon is coincident with the theory of electron transition caused by energy band splitting of the grain crystal surface.

测定结果显示微波辐射后硫酸钙粉末的表面自由能得到提高，从39.6mJm^(-2)增加到41.8mJm^(-2)，其主要原因是使硫酸钙表面能的极性成分得到了较大的提高。这一结果归于微波幅射引起晶粒表面的电荷重排，与晶粒表面能带分裂引起的电子跃迁理论是相吻合的。

Rather than using warp disrupt probes, the heavy interdictors use a module, the Warp Disruption Field Generator , which prevents all ships within its range from warping or jumping (including the heavy interdictor itself).

比起跃迁干扰探针，重型拦截舰可以使用更强力的装备，跃迁干扰场发生器，它能阻止场作用范围内所有的船只的跃迁，包括它自己。

Logging off inside a warp disrupt bubble (mobile warp disrupt or interdictor bubble) no longer triggers an emergency warp.

离开了跃迁抑阻设备后，将不能马上跃迁。

Especially, the difference of the nearest-neighbor hopping integral is due to the effect of the curvature of the carbon nanotubes. So, in fact there is a very narrow energy gap near the Fermi energy of unsquashed metallic zigzag carbon nanotubes, and, a slighter deformation is required to open a considerable energy gap in metallic zigzag carbon nanotubes than that in armchair nanotubes.

特别是，最近邻格点之间的跃迁积分的变化与碳纳米管的曲率紧密相关，因此实际上，理想金属型 zigzag 碳纳米管本身具有微小能隙，而施加比 armchair 碳纳米管小的多的压缩量，就可以使金属型 zigzag 碳纳米管在费米能处打开相当的能隙。

In the paper, what are introduced at first are the energy dispersions of quantum well, the interband transition and the exciton binding energy. Also some fabrication methods of GaN-based quantum well are mentioned.

首先，在第一章中介绍了量子阱的基本能带结构，带间跃迁以及激子束缚能，并简单介绍了几种量子阱的制备方法。

At last, Hartree-Fock and Density Functional Theory was used to calculate the Mulliken bond orders, HOMO and LUMO. The "principle of the smallest bond order" and the "principle of the easiest transition" were selected to judge the decomposition potential of the nitration products, and the results indicated trinitrotoluene would decompose easier than other product, and it was consistent with the experimental results.

最后，采用Hartree-Fock方法和密度泛函方法计算了各硝化反应中主要有机物的Mulliken键级、最高占有轨道能和最低空轨道能，采用&最小键级原理&和&最易跃迁原理&判断出三硝基甲苯最易分解，这与实验结果一致。

This is because that the solvent polarity affects ICT process in two ways: on the one hand, the ICT state is better solvated in more polar solvent, which favors the ICT process; whereas on the other hand, the rates of non-radiative decay and intersystem crossing of the ICT state are increased, which unfavors the ICT process.

这是因为溶剂极性增大，一方面ICT态被更好地溶剂化，ICT过程活化能降低，有利于ICT过程的发生；另一方面ICT态非辐射跃迁和系间窜跃速率增大，导致ICT荧光猝灭。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
