- A new algorithm is given, in which the factor of spherical wave front is removing explicitly.Thus the propagation of a focused beam could be evaluated indirectly from propagation of an unfocused beam. 为此提出了一种新算法:将球面波因子提出,将会聚光束的传输过程转化为非会聚光束的传输,从而间接地求得了聚焦光束的光场分布。
- spheric wave front 球面波前
- At each interface the spreading wave front is made discontinuous. 在每一分界面上扩展的波前出现间断。
- It starts with zero and grows to a maximum slightly behind the wave front. 它从零值开始，并在稍后于波阵面处增长到最大值。
- The formula of the first term for spheric wave propogating in ealstic medium has been derived,including the first terms of direet wave,reflection wave,and transmitted wave. 本文推导了球面波在弹性介质中传播的首项公式,包括直达波、反射波和透射波的首项。
- The radii are proportional to the time which has elapsed since the wave front occupied the position wi. 半径与波前占据wi位置以来能经过的时间成正比。
- This assumption is reasonably justified in the early stages, when the wave front is not far from ground zero. 这种假定在初期阶段波阵面离地面零点不远时是相当合理的。
- Theory of spherical wave decompositon and realization of dip stack. 球面波分解理论及其倾斜叠加方法的实现
- If a refraction or a reflecting body is irreqular, the wave front undergoes a deformation. 如果折射体或反射体是不规则的，波前即产生变形。
- The planes of the wave front and the reflecting surface are also normal to the plane of the figure. 波阵面的诸平面与反射面都与图面垂直。
- If a refraction or a reflecting body is irregular, the wave front undergoes a deformation. 如果折射体或反射体是不规则的,波前即产生变形。
- When the incident wave front reaches this point, the reflected wave is still some distance away. 当入射冲击波波阵面到达这一点,反射波离开它还有一段距离。
- Successive wave fronts in this case form a series of concentric spheres. 相继波前形成了一系列的同心球面。
- spheric wave reciprocity calibration 球面波倒易校准
- High-pressure acting on samples were produced by shock wave front converging in metallic ball. 在该装置上 ,利用冲击波由金属球体表面向中心汇聚形成的高压 ,对样品进行了冲击处理 ;

- All elements are radiating in phase, and the resultant wave front is perpendicular to the axis of the element array. 所有单元发射相位一致，合成的波前垂直于单元阵列轴线。
- Radiation from air shock wave front produced by explosion is an excellent microsecond illuminant. 炸药爆炸产生的空气冲击波阵面的辐射是高速摄影中的一种良好的微秒级持续时间的照明光源。
- The pressure in wave front is greatly attenuated while the shock wave propagates through the small opening of rocks. 当冲击波在破碎岩块间传播时，湍流流动受壁面的影响很大。冲击波在通过孔隙后其波阵面的压力衰减程度较大。
- In intersatellite communications, wave front aberration is main factor in affecting far-field behavior of signal beam. 星间光通信中,波前畸变是影响信号光远场特性的主要因素。
