It could be found by the investigation and statistics in World Health Organization (WHO)\'s International Electromagnetic Fields Project that the adoption of the international standards recommended by WHO has become the international main trend and it should be paid enough attention in China.
通过世界卫生组织(WHO)"国际电磁场计划"的调查统计可以看出,采用WHO推荐的国际标准已成为国际主流趋势,中国需要引起重视;目前国内输变电线路正常运行时周围环境中的磁场水平确实不高,但并不表明可将磁场限值降低到某个任意的水平,相反还需考虑到线路运行状况、采用新的导线技术和电缆运行等因素,这些均会使工频磁场水平显著增高。
2) International Geomagnetic Reference Field
国际参考地磁场

Based on the 8th generation of International Geomagnetic Reference Field, the global average westward drift rates of geomagnetic potential harmonic W-1～W-(10) during 1900～2000 are studied by using the Briggs method.
根据第8代国际参考地磁场的资料,本文采用Briggs方法对1900~2000年期间m=1~10次谐波的磁位的全球平均西向漂移速度进行了计算和分析,得出了与Hide的理论预测完全不同的频散特征,即地磁场西向漂移呈现出负频散特征。

IGRF(International Geomagnetic Reference Field) are the models of geomagnetic main field and secular variation.
IGRF(国际地磁参考场 )是有关地球主磁场与长期变化的模型 ,IGRF的误差主要来源于 :忽略外源场、球谐级数的截断、台站分布的不均匀、测量、忽略地壳磁异常场等 。

Based on the seventh generation International Geomagnetic Reference Field,the geomagnetic secular variation grid values were calculated,and the secular variation charts (,,,,,,) were drawn over China and adjacent areas for 1995～2000.
根据最新的第七代国际地磁参考场，计算并绘制１９９５～２０００年中国及邻区地磁长期变化图，分析了长期变化的空间变化。
