激发

There are three parts in our design: first, the dual-band branch line coupler provides two equal-power signals with 90° or -90° phase difference in each operating band. Second, the wideband switching circuit controls the two output powers of branch line coupler to excite the antenna structure for producing linear polarization wave or circular polarization wave. Third, the L-shaped fed conventional planar patch antenna is provided to overcome the coupling effect.

整体架构包含三个部分：L形电容耦合馈入式平面天线是为了克服平面式微带天线窄频的缺点；双频枝干耦合器提供天线在操作的两个频率点上各输出两组相差正九十度与负九十度的讯号，最后宽频的切换电路是将枝干耦合器的两组讯号作分配用以激发不同方向的天线以产生线性极化模态或同时激发两个垂直的天线以产生圆形极化模态。

To investigate the dispersive character of cylindrical Rayleigh wave, a finite element model is developed to simulate laser inducing cylindrical Rayleigh waves on the surface of an isotropic cylinder.

为了研究柱面上激光激发的瑞利波的色散特性，建立了激光在各向同性圆柱表面激发瑞利波的有限元模型。

Therefore, disease in the population has become more common recently. In view of this, submicron Negative-Ion powders and excited materials were adopted in this research. The submicron NI powders and excited material powders were treated with a dispersing agent and a ball mill used first, then it was blended evenly into water-borne polyurethane by a planetary deaerate stirring machine, and finally the water-borne PU composite films were coated onto release paper with a coating rod. The main purpose of this work is to manufacture a permanent composite film which is able to release NIs. Such film is expected to not only release amounts of NI but also absorb smells and effectively create fresh air.

有鉴於此，本研究采用次微米负离子粉体及激发材，先添加分散剂后利用球磨机做处理，再将次微米负离子粉体与激发材添加至水性聚氨基甲酸酯中，经由行星式脱泡搅拌机均匀混合，再以湿式涂布法，经由涂布棒涂布於离型纸上，脱膜后成复合薄膜，制备出於空气中释放负离子、吸收异味且清洁空气之永久型复合薄膜。

Foster enthusiasm."When people understand the importance of work, they lend their mental strengths," says Lee Ducat. But, oh, when they get excited about the work, all their energy gets poured into the job. That's a massive force!

激发热情。"当人们理解了工作的重要性时，他们便会用心工作，"杜坎特说，但是当他们对工作充满激情时，他们所有的活力都会激发出来，全身心地投入工作，这是一种巨大的力量。

For as to be in pain or distress of any kind excites the most excessive sorrow , so to conceive or to imagine that we are in it , excites some degree of the same emotion , in proportion to the vivacity or dulness of the conception .

因为，正如任何一种身心痛苦会激发出最为过度的悲哀感那样，构想或想象自己设身于其中也会激发起某种程度上的同样，和对想象或构想的概念的明确性和迟钝性成正比的悲哀感。

It is established that one close channel will be thought in the partial wave cross sections of elastic collision and rotational excitation. Five close channels must be considered in the partial wave cross sections of vibrational and rotational excitation at least.

结果表明：在研究氦氢碰撞体系的弹性碰撞、纯转动激发时，可以只考虑1个闭通道的影响，但在研究振转激发分波截面时，至少要考虑5个闭通道，才能得到比较准确的计算结果。

Elastic collision and inelastic collision are considered in oxygen molecule, nitrogen molecule by electron impart. The mail simulation results were as follow:(1)The variations of drift velocity and the average energy of electron with the E/N in O2 and N2 are obtained. The number of electrons for excitation, ionization, dissociation and dissociative ionization collision with the E/N and the energy of electron are analyzed emphatically.

考虑了各种弹性和非弹性碰撞过程，在纯氧气、纯氮气中，给出了不同简化场E／N条件下的电子漂移速度和平均电子能量的变化；着重分析了激发、电离、分解及分解电离碰撞的粒子数随E／N、电子能量的变化，同时计算了激发发射光谱的波长。

The luminescence properties were investigated with PL and PLE spectra.Emission peaks were at about 450 nm.This emission was ascribed to the recombination between the sulfur vacancy-related electron trap donor having an energy level just below the conduction band and the Ag-related hole trap acceptor above the valence band.

通过发射光谱和激发光谱对产品的光学性质进行研究，发射峰位于450 nm左右，归属于硫空位相关的电子陷阱施主和银相关的空穴陷阱受主的复合；激发峰位于333 nm左右，归属于ZnS基质的带边吸收。

An excitation band at 218 nm is also observed in the excitation spectra, which corresponds to the electron transition from the ground state to the conduction band.

在其激发光谱中观测到218 nm的激发峰，这归属于电子从Mn2+基态到导带的电荷转移跃迁所致。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
