svea meaning in English
斯韦亚
Examples
- The corresponding numerical investigations are carried out and show that for the pulses as short as sub - cycle , svea will cause the spatial singularity for both transverse and longitudinal components of the light field
在第三节里，我们考虑了超短脉冲光束在傍轴近似下的矢量传输特性，并且得到了横向场和纵向场传输的积分解。 - In particular , based on the complex analytical signal theory , the solutions for the components of a pulsed gaussian - like beam in rectangular symmetry are derived and compared with those derived from slowly - varying - envelop - approximations ( svea )
本部分给出了时间波形为gauss 、 hyperbolicsecant和lorentz的脉冲光束奇异性的计算模拟，并给出了解决这些奇异性的复解析信号( complexanalyticalsignal )解。 - The condition , under which the paraxial approximation is valid , is given . 4 . starting from the rayleigh diffraction integral , the propagation equation of ultrashort pulsed beams in dispersive media has been derived without making the paraxial approximation and slowly varying envelope approximation ( svea ) , which allows for relatively large angles
从瑞利衍射积分公式出发，未作慢变振幅近似和近轴近似的条件下，导出了等衍射长度超短脉冲高斯光束在色散介质中非近轴传输方程，可用来处理色散介质较大角度的传输。 - The two movies , sjoman ' s " alfred " and eriksson ' s " the shark who knew too much " were made before swedish broadcasting laws allowed commercial stations to interrupt movies with advertisements , and the svea court of appeals upheld a lower court ruling saying the station violated the directors " integrity and copyright , since they had not given permission for the breaks
瑞典一家法庭曾就此事做出过判决，认为第4电视台在播放影片时并未得到可以插播广告的授权，所以它实际上已经构成了对于两位导演作品的艺术完整性和版权的侵犯。这一判决目前已得到斯维亚上诉法庭的明确支持。 - But the complex analytical signal ( cas ) theory can erase this spatial sigu - larity . in this section , gauss , hyperbolic and lorentz pulsed gaussian beam have been derived and compared svea and cas solution by numerical simulatio n . in section 3 , by using fourier transform technique and applying the paraxial approximation in frequency domain , we derive an integral solution for the transverse and longitudinal components of the light field propagating in free space
接着，考虑了几种特殊的脉冲gauss光束( pulsedgaussianbeam ) ，结果显示，在此情况下缓变包络近似( slowly - varyingenvelopeapproximation )理论已不再有效，其失效的原因是，该理论导致了脉冲光束解的空间奇异性，并使脉冲光束不再具有符合物理意义的光束行为，而通过复解析信号的分析方法可以消除这种空间奇异性。
