| 1. | Constraints on silicate weathering rates in different settings : climatic or tectonic 不同构造带硅酸盐化学风化率的制约:气候还是构造 |
| 2. | The effects of cenozoic tectonic uplift on earth surface chemical weathering and global climate change 新生代构造抬升对地表化学风化和全球气候变化的影响 |
| 3. | Correlations between strontium isotope of river water and chemical weathering in karst areas , guizhou province 贵州河流河水的锶同位素与喀斯特地区化学风化作用 |
| 4. | For the mass balance equations , the average mechanical denudation rates would be estimated based on chemical weathering rates for the major basins of china 研究发现综合岩性整体上控制了中国主要流域盆地化学风化率的大小,但化学风化率一定程度上也受制于流域岩石的化学风化进程。 |
| 5. | ( 2 ) cia can not reflect the degree of chemical weathering of black shales precisely , and a - cn - k diagram can not reflect chemical weathering processes of black shales completely ( 2 ) cia值并不能灵敏地反映黑色页岩的化学风化程度, a - cn - k三角图解并不能完整地反映黑色页岩化学风化的整个过程。 |
| 6. | A combined effect of climate , relief , integrated lithology , vegetation and cultivated area seemed to explain the variability of modern chemical weathering and mechanical denudation rates 相比而言,西江和北江流域岩石的整体化学风化进程、 2大类岩性的化学风化程度均较之长江、黄河流域强烈的多。 |
| 7. | Samples and analysis methods hundreds of water samples from the upper reaches to lower reaches of the rivers were collected and stored in acid - washed polypropylene bottles from 1997 to 2001 in major watersheds of china 3条支流的硅酸盐类化学风化作用已达到了较稳定状态,而东江沉积物比西江、北江相 |
| 8. | In fact , as a very important part of material geochemistry cycle , chemical weathering and mechanical denudation plays a crucial role in affecting and changing the surface continent deeply 扣除大气降水、人类活动、大气co :等非岩石风化来源的物质后得到了中国17个主要流域盆地较为准确的化学风化率数值。 |
| 9. | The results show no obvious difference in the contents of major components in the different xiashu loess profiles , but some difference in the contents of readily leaching elements of loess and the chemical weathering intensity of loess among the different xiashu loess profiles 结果表明不同下蜀土剖面在主要组分含量上差异不明显,但在易淋溶元素含量和经历的化学风化程度方面存在一定差异。 |
| 10. | The 0 . 28xl0 ~ _ ( 9 ) t carbon derived from atmospheric co _ ( 2 ) is transferred from atmosphere and biosphere to the ocean by surface rock weathering processes . in order to monitor the quality of the river , it is also important to understand the natural flux of dissolved ions 珠江流域3条主要支流的化学风化过程存在明显差异,西江和北江流基本以碳酸盐类溶解为主,而东江河水扣除大气降水的来源外,溶解质基本出自硅酸盐类的风化。 |
