英汉例句
- It can be divided into 2 subfacies of fan delta-front and fan prodelta,and 6 microfacies.
可進一步分爲扇三角洲前緣和前扇三角洲兩個沉積亞相及六個微相。 - The sparse prodelta turbidite dist ributed on the eastern abrupt margin of the basin and the depositional systems came f rom the east .
後者發育於盆地中部的東緣陡坡帶 ,物源由東曏西推進。 - Distributary channel was well developed, prodelta was relatively not well developed and delta front was dominated by subaqueous distributary channel deposits.
研究區三角洲平原分流河道沉積極爲發育，前三角洲相對不發育，三角洲前緣也以水下分流河道沉積爲主。 - They include mainly subaqueous distributory channal,flood plain,river mouth bar,sheet bar,distal bar and prodelta clay sedimentary microfacies,and channel bar and flood plain splay submicrofacies.
不同沉積微相由於其儲層非均質性強弱不同，導致對油層物性、含油氣性以及油氣産能的影響不同。 - The interpretation of a typical sub-bottom profile reveals that the diapir of the Yellow River delta resulted from the interior deformation of soft prodelta layers at the delta front.
