在无限和真空的空间中,地磁场在强度上随距离3次方而衰减。
In a infinite and empty space the geomagnetic field falls off in strength with the third power of distance.
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.
背压对贯穿距离、喷雾锥角、喷雾轴心速度和浓度衰减率的影响均大于启喷压力。
It shows that the effects of back pressure on penetration, spray cone Angle, and decline rate of centerline velocity and concentration of the spray are greater than that of fuel injection pressure.
So this squared at the origin is going to be a very high probability, and it decays off as you get farther and farther away from the nucleus or from the center, and that's independent of the angle.
所以这个平方,在原点处非常高,随着离核子的距离,越来越远,它逐渐衰减,并且它和角度是没有关系的。
