This paper analyzes the differences of the space paremeters between the ship and other objects, thereby the characteristics of the various return waves are obtained.
利用这些差异可以排除不需要的杂波，识别船舶目标的回波。
As soon as they hit the object in front, the waves will return to the glove.
一旦碰到前面的物体，波浪就会回到手套上。
These waves reflect (反射) off surfaces all around and return to my ears.
这些波段经过周围表面的反射后，又回到我的耳朵里。
While smooth surfaces send back a reversed, right-polarized wave, rough areas return left-polarized waves.
光滑表面会反射一个反向的优选极化波，而粗糙地区的反射波是左旋极化波。
The emerging sunspot region seems to boost the local speed of sound, thereby hastening the refracted return of sound waves passing through that part of the solar interior.
浮现的黑子区似乎能使当地的声速增加，从而使声波更快地通过这个区域。
SPWM is a set of constant amplitude but unconstant width rectangular serial pulse produced by control return circuit to approximate sinusoidal voltage waves.
(正弦脉宽调制)是由控制回路产生一组等幅而不等宽的矩形脉冲列，用来近似正弦电压波。
Love is constantly bursting in the long river of life the beauty of the waves, but the river can't return back due to appreciate the beauty of the waves.
爱情是生命长河中不断绽开的美丽的浪花，但长河不能因欣赏美丽的浪花而回流不前。
At layer boundaries, that is, a place where different materials with different elastic parameters come into contact with one another, components of the waves are reflected and return to the surface.
在地层的交界处(指具有不同弹性参数的物质相交地带)，部分震波会反射到地表。
