1·Impermeable clay limits downward percolation of water and fulvic acids, reducing chemical weathering and podzolization.

不可渗透的粘土限制了水和黄腐酸的向下渗透，从而减少了化学风化和土壤灰化作用。

2·Chemical weathering was beginning to attack the unweathered bedrock.

化学侵蚀作用开始攻击还未侵蚀的岩床。

3·Because of discontinuity, chemical weathering can add water-rock interface and raise mineral dissolution rate.

由于非连续特性，化学风化可增大水岩界面，提升矿物溶解反应的规模及速率。

4·Strong chemical weathering underwent by the Xiashu loess might be related to strong monsoon climate in the lower reaches of the Changjiang River.

下蜀土较强的化学风化过程可能受长江下游地区较强的季风性气候控制。

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

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。

6·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.

频率曲线众数峰含量随深度的变化，不但指示了化学风化趋势，而且反映了风化程度的变化梯度。

7·It is important to ascertain the role of sulfuric acid in carbonate weathering so as to understand the chemical weathering rate carbonate rocks, CO2 consumption and global carbon cycle.

在碳酸盐岩地区，流域侵蚀过程中硫酸是否参与，对于我们正确理解流域化学风化速率，以及流域侵蚀对大气co2的消耗和全球碳循环等都有重要的意义。

8·Chemical index of the illite samples is higher than 0.5, indicating that clay minerals had undergone strong chemical weathering and interior of the Basin had a relatively warm and wet climate.

同时，所有样品伊利石化学指数值均大于0.5，说明粘土矿物经历了强烈的化学风化作用，盆地内部为暖湿气候。

9·Research is needed on chemical methods to accelerate the natural weathering process by which minerals form carbonates.

需要就化学方法加快矿物转化为碳酸盐的自然风化过程进行研究。

10·The ores with different weathering degree have different characteristics in mineralogy and chemical composition. Therefore, they can be quantitatively distinguished according to the chemical analysis.

不同风化程度的矿石有不同的矿物学和化学组分特征，因而可以根据化学分析结果作定量判别。
