| 1. | Pre - salt sediment group , salt sediment group and post - salt sediment group 在剖面上可分为三套地层组合,即盐下层系、含盐层系和盐上层系。 |
| 2. | The deep - water in situ deposits and deep - water allogene deposits develop flysch rhythmic sequences 深水原地沉积与异地沉积在剖面上组成了复杂的复理石韵律。 |
| 3. | With the enhancement of soil development degree , the difference in each physical and chemical characters are larger 随发育程度增强,表层厚度增加,各理化性质在剖面中差异增大。 |
| 4. | The change of ancient climate and environment was speculated according to the content change of caco3 on the section of hole 1146 根据1146孔caco _ 3含量在剖面上的变化,推测了古气候和环境的变化。 |
| 5. | Based on mass data analyses , the changes of sulfur , paraffin , colloid and asphaltene contents of crude oil in profile are studied 摘要根据大量分析资料,研究了石油中的硫、石蜡、胶质和沥青质在剖面上的变化规律。 |
| 6. | These internal - tide deposits possessed five types of vertical successions and formed rhythmic deposit combinations with cyclicity in the vertical section 它们具有5种垂向沈积层序,在剖面上常形成多旋回韵律性沈积组合。 |
| 7. | In conclusion , the variable degree of the soil water properties and bulk density in different layers is water content > wilting point > field capacity > saturation > bulk density 总的来看,各水分特性在剖面各层的变异情况为:含水量>萎蔫含水量>田间持水量>饱和含水量>容重。 |
| 8. | These nine environmental changes were well reflected by the variations of coarseness and fineness of grain - size of fluvial sedimentary profiles near dongweiqiao site of tang dynasty . 3 这不仅在剖面各层的粒度累计含量可以清楚地反映出来,且各个粒度参数一md 、 mz 、 o 、 sk和kg也同样具有显著响应。 |
| 9. | 3 . at the vertical direction of the section , the grain - size distributional coarse and fine rhythms vary very pronouncedly with the alternation of sedimentary facies , which is clearly shown not only in the grain - size percentage in this section but also in the response from different grain - size parameters 在剖面的垂直方向,粒度的粗细韵律分布随沉积相的变化非常明显。这不仅在剖面上粒度的百分含量可以清楚地反映出来,且各个粒度参数也同样具有显著响应。 |
| 10. | The variation of coarseness and fineness of the component particles in baijiaziu profile and mafangtan profile is caused by river impetus of weihe river , including runoff volume and velocity of flow , which is closely related with climatic factors in guanzhong basin , such as precipitation , temperature and rainfall 白家嘴与马坊滩河流沉积物剖面粒度变化与渭河水动力变化直接相关,而渭河水动力条件又与渭河流域区域气候变化有关。因此,粒度在剖面上的变化实质上是气候波动的结果,利用其变化可重建河流沉积物形成以来的水文、气候环境的演化历史。 |
