The observation quality of the baseline value is an important indicator to synthetically evaluate the observation data quality of geomagnetic observatories. 摘要基線(xiàn)值的觀(guān)測質(zhì)量是綜合評價(jià)地磁臺觀(guān)測資料質(zhì)量的一個(gè)重要指標。
In the Campania region, baseline and background values are often coincident, where the samples represent catchment basins away from urban or industrial areas. 在坎帕尼亞地區，樣品代表的是遠離市區或者工業(yè)區的匯水盆地，所以基線(xiàn)值和背景值經(jīng)常是吻合的。
