The second part of the dissertation comprehensively analyses geological background and erosional geomorphological conditions in the test regions, elaborates on evolution characteristics of erosional environment in the regions, probes regional distinguishing regularity of erosional geomorphological patterns as well as their developing and evoluting features in loess fields, and places emphasis on discussing developing and evoluting trends of soil erosion in the watershed.

本文的后半部分对试验区的地质背景与侵蚀地貌条件进行了综合分析，阐述了区域侵蚀环境的演化特征，探讨了黄土地区侵蚀地貌区域分异规律及其发展演化特征，并着重讨论了流域土壤侵蚀的发展演化趋势。

The four types of sequence interfaces embody ten types, such as paleocrust of weathering, drossy layer, river rejuvenation, palaeokarstification surface, scouring and erosional surface of slope gravity flow, erosional surface of basin turbidity current, volcanism surface, transfer surface of lithologic characters or lithofacies, onlap surface and maximum flooding surface.

以此为基础，将右江盆地泥盆系—中三叠统划分为6个二级层序和49个二级层序。

The relationship be-tween the erosional soil surface and the erosional soil modulus is nonlin-er,but a power relation,that is:M=

建立了土壤侵蚀面与区域侵蚀模数间的回归模型，M=

Following the rising and dropping of sea level, river erosional base have been changed severely, while there are some erosional or siltational processes happened in vertical direction at river mouth and in its low reach, there are also with large scale migration in plain direction.

随海面升降变化，河流侵蚀基准面发生重大变化，河流河口与下游段在发生侵蚀—淤积垂向变化的过程中，平面上亦表现为大范围的迁移。

Moreover, human activities play a more and more important role in the development of tidal flat. The concentrated coastal engineering change the dynamic environment of the tidal flat, and the exploitation of oil, natural gas and groundwater results in surface subsidence in the coastal area. In addition, sea level rise and the accompanied increase of storm surge frequency and intensity, will strengthen the erosional process, reduce the tidal flat area, coarsen the sediment, made the slope steep, and cause other environmental effects.

人类活动的环境效应对渤海潮滩发育的作用越来越明显，环渤海地区密集的海岸工程将改变原始的潮滩动力环境；石油、天然气、地下水的开采会导致海岸带发生地面沉降；海平面上升以及与其相伴随的风暴潮作用频率与强度的增加都将会使渤海潮滩的侵蚀过程加强、潮滩面积缩小、滩面物质粗化、坡度变陡，并产生一系列的相关的环境效应。

Cumulate plagioclase appears abruptly at the base of the F unit, which rests on an erosional disconformity.

堆积的斜长石在位于侵蚀假整合之上的F单元的基底突然出现。

Cumulate plagioclase appears abruptly at the base of the F unit, which rests on an erosional disconformity

堆积的斜长花岗石在位于侵蚀假整合之上的F单元的基底突然出现。

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.

综合岩相观察结果，建构一个符合台湾西南部更新世珊瑚礁与基底泥岩接触关系的沉积相模式；其中，基底泥岩顶部的不规则冲蚀面、充填碳酸盐胶结泥岩砾与碳酸岩烟柱的漏斗状沉积，以及块状冷泉碳酸盐岩的出露，可能均为区域地质构造活动时期所造成；至於与含化石泥岩同时沉积的砾岩相，可能均为基底泥岩在快速浅化的过程中所沉积，标志古环境由矽质碎屑快速转变为碳酸盐环境的过程。

The landform of this area is a thpyical erosional and depositional topography of semiarid one.

这个地区是一种典型的半干旱地区的腐蚀和沉积地形。

Based on the National '973' Project, National Physical Science Fund and, Science and Technology Project of Shanghai, this paper studies the complexity of erosional/accretionary evolution in the Yangtse Estuary.

另一方面，长江口及其邻近区域又是我国重要的经济活动区之一。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
