斯托克斯用惠更斯原理推导的,用来表示一个波的主要能量向前移动、阻止向后传播的因子:  
(∂ blik’ wi tē) A factor derived by Stokes for use with Huygens’ principle to show that the major energy in a wave moves forward and to prevent backward propagation:  
 
  
 
<center><math> cos{\frac{\phi}{2}} \approx \frac{1+cos{\phi}}{2} </math>,</center>
 
<center><math> cos{\frac{\phi}{2}} \approx \frac{1+cos{\phi}}{2} </math>,</center>
  
 
where <math>\phi</math> is the angle between the directions of reradiation and of approach.
 
where <math>\phi</math> is the angle between the directions of reradiation and of approach.
