方差分析法在定点核旋观测资料质量检验中的应用

本文以地磁场的空间相关性为物理依据，以测点间测值线性回归方程的显著程度，为测点测值的质量检验标准，采用方差分析和相关系数法，以月为时段，分别计算了省内１９９２年１至１０月，１０个地磁台站的Ｆ，ｒ，Ｓ检验结果。结果表明，两种方法的检验效果相似。而方差分析法，在分辨率和准确性方面，明显优于相关系数法。按计算时段，选取标准台的办法，利于克服单一标准台的不足和空间磁场差异性变化对测点测值质量评估的影响。

APPLYING VARIANCE ANALYSIS TO QUALITY EXAMINATION OF OBSERVATION DATA OF NUCLEAT PRECESSION MAGNETOMETER

We take obvious degree of linear regression equation of observations val-ue for various observing station as the standard of quality examination of observed reading onthe basis of space correlation of magnetic field.Making use of methods of variance analysisand correlation coefficient, the observations of 10 geomagnetic stations,which are F,r andS from Jan. to Oct.,1992, have been computed, respectively. The results show that twomethods are similar for quality examination, and variance analysis method is to gain advan-tage over one of correlation coefficient as respects resolving power and accuracy.
