chemical weathering

基本解釋

The results show that the soils have, in varying degree inherited some properties of purple sedimentary rocks for their very weak chemical weathering.
結(jié)果顯示，紫色沉積巖發(fā)育的土壤，在一定程度上繼承了母巖的特點(diǎn)，化學(xué)風(fēng)化作用微弱。
The variation of frequency curve's mode peak content with the increasing of depth, shows not only the trend of chemical weathering but also variation gradient of weathering extent.
頻率曲線眾數(shù)峰含量隨深度的變化，不但指示了化學(xué)風(fēng)化趨勢(shì)，而且反映了風(fēng)化程度的變化梯度。
And, in the maritime Antarctica, various modern periglacial processes play an important role in weathering, material transportation and soil formation. Besides, chemical weathering processes, incl…
闡述了本區(qū)內(nèi)化學(xué)風(fēng)化的主要過程、機(jī)制與產(chǎn)物，同時(shí)指出生物因素在本區(qū)的巖石風(fēng)化與原始土壤形成過程具有重要意義。

化學(xué)風(fēng)化
We suggest that the felsic component rocks were dominant in the source area which has undergone middling chemical weathering. These sedimentary rocks were deposited in active continental margins.
它們具有巖石地球化學(xué)相似性,其源區(qū)物質(zhì)以長(zhǎng)英質(zhì)巖石為主,中等化學(xué)風(fēng)化程度,原巖沉積于活動(dòng)大陸邊緣構(gòu)造背景。

化學(xué)風(fēng)化
We study the chemical weathering and its rate in the drainage basin,CO_2 consumption rate(volume) caused by chemical weathering of rocks,and the transport characteristics of inorganic carbon. Preliminary conclusions are presented as follow:1.
本文通過2007年6月和7月對(duì)黃河流域的水文地球化學(xué)特征以及干流河水中無機(jī)碳進(jìn)行考察和研究,探討了黃河流域發(fā)生的主要化學(xué)風(fēng)化反應(yīng)、流域盆地的化學(xué)風(fēng)化率、巖石化學(xué)風(fēng)化的大氣CO_2消耗率(量),和無機(jī)碳的輸運(yùn)特征。
