总体上表现以半干旱的环境为主导化学风化作用相对微弱。

Indicating that the semi-arid environment was dominant with much weaker chemical weathering .

化学风化作用具有由南向北增强趋势；

In addition , there is the trend of increasingly strong weathering from south to north .

结果显示，紫色沉积岩发育的土壤，在一定程度上继承了母岩的特点，化学风化作用微弱。

The results show that the soils have , in varying degree inherited some properties of purple sedimentary rocks for their very weak chemical weathering .

Si/Al或SiO2/R2O3常常作为表生化学风化作用强度的重要指标。

The ratios of SiO 2 / Al 2O 3 or SiO 2 / R 2O 3 are usually used as indices of supergene chemical weathering intensity .

同时指出，泥石流沉积属于近源快速沉积，沉积时遭受的物理风化作用和化学风化作用均较微弱。

During the period of its deposition , the source area was quite near and quickly deposited , and both physical and chemical weathering were all rather weak .

寒冷时期，气候偏干，入湖水量减小，湖泊萎缩，流域化学风化作用减弱。

Whereas the cold-arid climate resulted in a decrease of inflow to lake , which corresponded to lake water level drop , lake area shrank and chemical weathering weaken .

生物无时无刻不参与地球表层矿物和岩石的风化，但以往的研究大多注重物理风化与化学风化作用，对生物风化作用关注很少。

Although organisms always participate in the weathering of mineral and rock on the earth surface , much attention was paid to the physical and chemical processes , but little attention to the biological process in previous studies of weathering .

而硅铝率（或Al2O3SiO2比值）和（高岭石+伊利石）石英比值在全岩研究中代表化学风化与侵蚀作用的共同强度；

The ratios of Al 2O 3 / SiO 2 and kaolinite + illite vs quartz for whole rock indicated the intensities of both chemical weathering and erosion .

Geochemistry and chemical weathering of Nelson periglacial sediments , Antarctica

黄土地球化学残积系数、钠钙比和化学风化指数数值增大、退碱系数数值减小时，指示化学风化作用增强，在很大程度上揭示出当时具有较强的夏季风活动。

The intensity of chemical weathering increases with increasing of eluvial coefficient constituted by geochemical elements , ratio of Na to Ca and the value of chemical weathering increasing , and decreasing of alkali index , which implies strengthening of summer monsoon .

研究结果表明：辽宁省景观地球化学标型元素是Al（强烈富集）和Ca（大量流失），出露地表的岩石以遭受化学风化作用为主；

The results suggest that the typochemical elements are Al ( intense enrichment ) and Ca ( heavy dilution ) in Liaoning geochemical landscape ; the chemical weathering is primary agent for the surface rock in Liaoning province ;
