求翻译：当无线信号在大气环境中传播时，由于多种因素的影响，信号强度会随着其传播距离增加而衰减，信号强度和传播距离间存在某种函数关系。是什么意思？

When the wireless signal propagation in the atmosphere, due to many factors, signal strength will increase with the propagation distance attenuation, signal strength and transmission as a function of distance.

When the wireless signal in the atmosphere when you spread in the environment, as the result of many factors, the signal strength increases with the increase of the distance attenuation, the signal strength and the distance between a function exists.

When the wireless signal propagation in atmospheric environment, since the impact of a variety of factors, will increase as its range and attenuation of signal strength, signal strength and range of a function relationship.

When the wireless signal disseminates when the atmospheric environment, as a result of many kinds of factor influence, the signal strength can increase along with its propagation distance weakens, between the signal strength and the propagation distance has some kind of functional relation.
