secondary deposit meaning in Chinese
次生沉积
次生矿床
二次矿床
Examples
- The prototype is made by a concave sphere primary and a plane secondary deposited the mo / si multilayer on the fused quartz substrates . the reflectivity peak and the reflectivity uniformity of the multilayer mirrors are respectively 25 % and around + 2 . 5 % at 17 . 1nm
望远镜主镜为球面,次镜为平面,所用反射镜为在熔石英基底上镀制mo si多层膜的euv波段反射镜,在17 . 1nm的反射率25 ,反射率的均匀性2 . 5 。 - 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
实验结果表明:粘粒粉沙比值能很好地指示粉尘堆积物的次生粘化作用;磁化率和全铁很好地指示生物风化成壤作用; sr和rb sr比值能很好的指示生物风化成壤作用和淋溶作用;总有机碳( toc )含量的高低,在一定程度上反应了土壤发育过程中气候和植被状况的变化,指示着成壤过程中腐殖质化的程度; caco3含量的变化,可以反映了黄土古土壤形成时的风化成壤作用的强弱程度,指示成壤过程中的淋溶作用和次生碳酸盐化作用;并且各指标所指示的成壤环境和成壤强度存在明显的区域差异,即渭河流域土壤的生物风化成壤作用、次生粘化作用和淋溶作用均表现出南部强于北部。
