本文将资源一号（CBERS-1）星内粒子探测器的观测结果与辐射带模式（AE 8/AP 8）进行了比较。结果表明，在南大西洋异常区的观测结果与模式的预测结果基本雅阁，而在南、北方极光带的电子通量观测值远低于AE 8模式的预测值。根据NOAA卫星的观测结果，认为这种差异是由于SAA和极光带区域粒子倾角分布的差异造成的。在南大西洋异常区粒子倾向于各向同性分布，而在极光带粒子各向异性明显，投掷角接近90°的粒子通量比0°投掷角附近的粒子通量大得多.
The observations of the particle detector inside ‘ZY-1' (CBERS-1) satellite are compared with the radiation belt models (AE8/AP8). It is found that the measurements in SAA(Southern Atlantic Anomaly) are in accord with the predictions by the models, while the measured electron flux is much lower than the prediction by the AE8 model in the regions of southern and northern aurora belts. According to the observations of NOAA satellite, this difference is considered to be caused by the difference of the particle pitch angle distributions in SAA and the regions of the aurora belts. The particle's flux in SAA is inclined to be isotropic, while in the regions of the aurora belts it is obviously anisotropic where the particles distributed near 90° pitch angle are much larger than that distributed near 0° Pitch angle.
