| 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. | 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。 |
| 5. | 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。 |
| 6. | 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。 |
| 7. | 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。 |
| 8. | This paper probed the theory and modeling on the planation surface through its definition , discrimination , classification , distribution , formation , dating , and so on . we also made 3d presentation and analysis of the planation surface by using photoshop , mapgis and excel
本文从夷平面的定义和识别、分类及分布、形成、年龄等几个方面进行了夷平面理论和实践的探讨，并利用photoshop 、 mapgis 、 excel等对夷平面进行了三维显示和分析。 |
| 9. | Planation surface is a wide - ranging and undulating surface formed by planation in a long and relative stable period or in a decreacing - development period . it is near the base level and there always exists some deposits such as crust of weathering above it . planation surface is often uplifted or buried by the later tectonic activities
夷平面是在长期的地壳相对稳定时期或地壳下降发展阶段，由广泛的夷平作用以截断面形式横切所有先成的地层和构造的接近侵蚀基准面的平缓的地表形态，其上常有风化壳等碎屑堆积，常遭到后期的抬升切割或埋藏，分布于地球的各纬度带。 |
| 10. | Original planation surface has some features , for example , it appears in large area with low altitude , small gradient and taking a long formation period , etc . discrimination of planation surface is based on plotting and field investigation and by using statistical methods and " 3s " technique
原始的夷平面具有分布面积较大(全流域范围) 、坡度较小、高度较低、形成所需时间较长、有夷平作用的痕迹等特点。基于野外考察和室内作图，可利用数学统计方法和“ 3s ”技术进行夷平面的识别，这加强了夷平面研究的精确性、客观性和定量性。 |
