  polarization coefficient
    Thus in common receiving gathers,firstly calculate the polarization coefficient of direct wave for each trace,and then use the resulted coefficients as weights to determine the main polarization direction in detector coordinates via weighted least square method,and finally,orientations of geophones are esti- mated.
    因而,可以在共检波点道集中,首先计算各道直达波的偏振系数,再用偏振系数作为权系数,采用加权最小二乘算法直接计算出检波器坐标中的主偏振方向,以此准确估算出检波器方位。

  polarization coefficient
Analytical calculation of a fourth-order vacuum polarization coefficient
      
A quadratic polarization coefficient of the gapK12?0.2 meV/(μC2 cm-4), independent of temperature, has been found.
      
Velocity and polarization coefficient are used to describe the activity and orientation of animals.
      
The polarization coefficient may change with an intrinsic rhythm: during the morning, the phototropic reaction is generally more positive than during the afternoon.
      
G test and variance analysis show that light intensity and wavelength can affect the orientation and the velocity of male individuals, but do not significantly affect the polarization coefficient of female individuals.

The orientation of crosswell 3-D component geophone is critical to processing of crosswell seismic data.Crosswell seis- mic observations are usually based on sectors.First arrivals in common receiving gather should have the same axis of polariza- tion.Thus in common receiving gathers,firstly calculate the polarization coefficient of direct wave for each trace,and then use the resulted coefficients as weights to determine the main polarization direction in detector coordinates via weighted least square method,and...

井间三分量检波器的方位确定是井间资料处理的关键。井间地震观测通常采用分扇区的观测方式,其共检波点道集中的初至波应该具有相同的偏振轴。因而,可以在共检波点道集中,首先计算各道直达波的偏振系数,再用偏振系数作为权系数,采用加权最小二乘算法直接计算出检波器坐标中的主偏振方向,以此准确估算出检波器方位。这种处理方式能得到稳定可靠的井间波场水平径向分量和切线分量。
