该原则同样适用于侧光：侧光源离被摄主体近时，整个画面的光线衰减将比光源离主体远时更明显。
The same holds true for sidelighting: With a light close to the side of your subject, the falloff of light across the frame will be more pronounced than if the light is farther away.
近炮检距处地震波的衰减较之远炮检距的相应衰减量更能准确反映地层的岩性信息。
The attenuation of seismic wave in near offset can more correctly reflect the lithologic information of formation than that in far offset.
由于卫星通信信道长，传输距离远，电波要穿过对流层和电离层，易使信号衰减，引入噪声，造成误码。
Due to satellite communication's long channel, far distance transmission and its wave through troposphere and ionosphere often brings the signal deamplification, noise and wrong code.
