This paper proposed a new monitoring method based on reflectionattenuation, which computes temperatures directly from the B-ultrasonic images and needs no more other equipments.
本文基于反射衰减法提出一种新的直接对B超图像进行处理得到温度的监测方法，无须增加其他附加设备。

The sphere affects the incident by the refraction, diffraction, reflection, absorption and attenuation of impurity.
这种球体对入射光存在折射、衍射、反射、吸收和杂质对入射光波的衰减作用等影响。

The ground reflection and attenuation must be properly accounted for in order to use the source spectrum measured at the site of the observer to predict the actual source spectrum in the free field.
