We also considered the 3d presentation and analysis of the planation surface 文章還進(jìn)行了夷平面三維顯示和分析的初步探討。
The age of planation surface means the end of the planation 夷平面的年齡就是夷平作用停止的年代,即夷平面開(kāi)始破壞解體的年齡。
Chronology of planation surface is one of the most important part of the study 夷平面的測(cè)年是夷平面研究中非常重要的一個(gè)方面。
This paper ' s main aim is to narrate the technology and the principle of agent planation in two layers of metal process 摘要本文主要敘述了雙層金屬布線中介質(zhì)平坦化的工藝及原理。
Different type of planation surface has different formation , the difference of planation results in the difference of planation surface 不同類(lèi)型的夷平面有不同的形成過(guò)程,夷平作用的差異導(dǎo)致了夷平面類(lèi)型的差異。
Phase - transition analysis , age - boundary line analysis , correlation and crust of weathering analysis are all used in determining the age of the planation surface 本文介紹了相過(guò)度法、年界法、相關(guān)沉積法和風(fēng)化殼法等測(cè)定夷平面年齡的方法。
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 更新世中期本區(qū)湖沼廣布。更新世晚期是本區(qū)平原化的主要時(shí)期。塑造了北京平原現(xiàn)時(shí)地貌的基本格架。
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 夷平作用大致可分為準(zhǔn)平原化夷平作用、山足夷平作用、凍融夷平作用和雙層水平面夷平作用等幾種類(lèi)型。
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 夷平作用是以侵蝕為先導(dǎo),輔以搬運(yùn)、堆積、伴隨有地形的蝕低蝕退,以接近侵蝕基準(zhǔn)面為目標(biāo)的一種外力組合。
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 夷平面理論研究與初步模擬? ?中文摘要影響夷平面形成的主要因素有前期大地構(gòu)造、侵蝕基準(zhǔn)面、氣候、巖性、時(shí)間和后期構(gòu)造運(yùn)動(dòng)等。
the process of erosion whereby a level surface is produced
百科解釋
Planation is a geomorphological process which creates nearly flat surfaces by fluvial (river), aeolian (wind) and marine processes. The process is erosional and takes millions of years, and its legacy from the tertiary period (65-2Ma) is present in many of today's landscapes.
