The seismic methods, reflection and refraction, are currently used in mining exploration . 地震法包括反射波法和折射波法，常用于金属矿勘探。
Reflection will fall within a narrow wedge on the plot that is centered on its vertical axis . 反射波落在图上以垂直轴为中心的一个狭窄的楔状带内。
Finally, we determine the changes in the phases of the components of the reflected and the incident wave . 最后，我们求反射波和入射波各分量的位相变化。
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。
An interference field exists in space in the region where the two reflected waves are superimposed on each other . 两个反射波相互重叠的空间出现一个干涉场。
Even with the new kind of display, correlation of reflections is not always as simple as it may appear . 即使采用这种新型显示方式，反射波的对比往往亦非易事。
This first will be due to the incident blast wave and the second, a short time later, to the reflected wave . 第一个是由入射爆震波引起的，第二个是稍晚产生的反射波。
Any process that will compensate for such distortions of the initial pulse should improve reflection quality . 任何补偿这类初始脉冲畸变的处理，都能改善反射波的质量。
Such cables record reflections with less interference from noise than was usually possible with earlier types . 用这类电缆纪录反射波，干扰噪音比以前应用的各类电缆要小。
The conversion of observed reflection time to a correct geometrical picture of the subsurface involves a number of steps . 将观察的反射波时间转换成正确的地下界面几何图形，需经过好些步骤。
