| 1. | We also considered the 3d presentation and analysis of the planation surface
文章还进行了夷平面三维显示和分析的初步探讨。 |
| 2. | The age of planation surface means the end of the planation
夷平面的年龄就是夷平作用停止的年代，即夷平面开始破坏解体的年龄。 |
| 3. | Chronology of planation surface is one of the most important part of the study
夷平面的测年是夷平面研究中非常重要的一个方面。 |
| 4. | This paper ' s main aim is to narrate the technology and the principle of agent planation in two layers of metal process
摘要本文主要叙述了双层金属布线中介质平坦化的工艺及原理。 |
| 5. | Different type of planation surface has different formation , the difference of planation results in the difference of planation surface
不同类型的夷平面有不同的形成过程，夷平作用的差异导致了夷平面类型的差异。 |
| 6. | Phase - transition analysis , age - boundary line analysis , correlation and crust of weathering analysis are all used in determining the age of the planation surface
本文介绍了相过度法、年界法、相关沉积法和风化壳法等测定夷平面年龄的方法。 |
| 7. | The late pleitocene was the essential duration for the planation of the region , when the basic frame - work of the present geomorphology of beijing plain was constructed
更新世中期本区湖沼广布。更新世晚期是本区平原化的主要时期。塑造了北京平原现时地貌的基本格架。 |
| 8. | There are lowering and backing of the ground when it was planated . planation can be classified into many types such as peneplaination , pedimentation , cryoplanation and double leveling surfaces planation
夷平作用大致可分为准平原化夷平作用、山足夷平作用、冻融夷平作用和双层水平面夷平作用等几种类型。 |
| 9. | Planation is a combination of external agents . erosion is the primary significance in that it cuts all the strata formed previously and in the combination with transportation and accumulation , directly affects the formation of planation surface
夷平作用是以侵蚀为先导，辅以搬运、堆积、伴随有地形的蚀低蚀退，以接近侵蚀基准面为目标的一种外力组合。 |
| 10. | According to geologic basement , it can be divided into stable - floor planation surface and active - floor planation surface . according to climate zone , it can be divided into pediment and pediplain , double leveling surfaces and etchplain , peneplain and cryoplain
夷平面理论研究与初步模拟? ?中文摘要影响夷平面形成的主要因素有前期大地构造、侵蚀基准面、气候、岩性、时间和后期构造运动等。 |
