  11. The two sunspots of a pair have different polarities, one would be a magnetic north and the other is a magnetic south. thus, we believe that there are magnetic field lines joining the two sunspots of a pair. the strong magnetic field locks the gas of the photosphere in places and inhibits the hotter gas below to rise at the sunspots

    黑子經常成雙成對出現，每對皆由極性相反的黑子組成，若一個為磁北，另一個必為磁南，由此我們估計每對黑子皆由磁力線所連系，強大的磁場牽制著光球層上的氣體，並阻止了下層較熾熱的氣體上升至黑子范圍，結果黑子比太陽表面其他地方溫度較低。

  14. The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north

    實驗結果表明：粘粒粉沙比值能很好地指示粉塵堆積物的次生粘化作用；磁化率和全鐵很好地指示生物風化成壤作用； sr和rb sr比值能很好的指示生物風化成壤作用和淋溶作用；總有機碳（ toc ）含量的高低，在一定程度上反應了土壤發育過程中氣候和植被狀況的變化，指示著成壤過程中腐殖質化的程度； caco3含量的變化，可以反映了黃土古土壤形成時的風化成壤作用的強弱程度，指示成壤過程中的淋溶作用和次生碳酸鹽化作用；並且各指標所指示的成壤環境和成壤強度存在明顯的區域差異，即渭河流域土壤的生物風化成壤作用、次生粘化作用和淋溶作用均表現出南部強于北部。
