您要查找的是不是:
- For distributions in several variables, singular supports allow one to define wave front sets and understand Huygens' principle in terms of mathematical analysis. 对于多变量的分布,奇支集也可以更精确地被描述为,从而可以利用数学分析来理解惠更斯原理。
- The news from the front set him in the twitters. 前方来的这则消息使他紧张不安。
- 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。
- Just like in the roving step, the front set of rollers rotates faster than the back one. 与粗纱工序相似,前罗拉的转速高于后罗拉的转速。
- 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。
- In spinning,the front set rotates about30 times faster than the back set. This difference in steed attenuates the yarn and makes it even, smooth and uniform. 一般前面一对罗拉的转速是后面一对罗拉的30倍,这样速度的差使纱条抽长拉细,变均匀,变光滑。
- 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。

- 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。
- Coming in a handy reusable container, the front set contains 6 various springs while the rear set has 7, making for a cost effective way to obtain all possible spring combos. 未来在一个轻便的可重复使用的容器,前六集包含各种温泉的同时,后方载有7名,使一个符合成本效益的方法以取得一切可能的弹簧组合。
- 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。
- 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。
- Such wave fronts are seperated from one another by one-half wavelength. 这种波阵面彼此间隔半个波长。
- 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。
- Such wave fronts are separated from one another by one-half wavelength. 这种波阵面彼此间隔半个波长。
