风化壳上部是发育好的红色古土壤，中部是含铁质胶膜的风化破碎黄土，下部是不含铁质胶膜的风化破碎黄土。

It is considered that the Tertiary unconformity in Jiyang Depression can be divided into three types: typeⅠ1, typeⅠ2 and typeⅡ. Unconformity generally consists of weathered clay, semi-weathered rock and unweathered rock.

研究认为济阳坳陷第三系不整合可划分为三类：Ⅰ1型结构、Ⅰ2型结构和Ⅱ型结构，完整的不整合结构包括风化粘土层、半风化岩石、未风化岩石。

The evaporation of some oils and their emulsifies was modeled with pan evaporation method, and the characteristics of the evaporation in different states was inspected. The equations of evaporation rate and the factors of inhibitory action of emulsification on evaporation have been obtained. The dynamics mechanism of emulsification has been discussed based on the observation and analysis of the characteristics of oil and water motion. The processes of spilt oils weathering have been integrated by the composition and states of oils in this prediction model.

本文主要是从目前研究的薄弱环节作为研究突破口，用浅盘蒸发法对原油及其乳化物的蒸发进行模拟，考察不同原油在不同阶段和乳化状态下的蒸发特征，得出蒸发速率方程及乳化对蒸发抑制作用因子；观测和分析油水运动规律，分析乳化动力学过程；以组成和状态是决定风化特征的主要因素和联系各风化过程的纽带这一思想为基础建立溢油风化预测模型。

The interlayer oxidized zone and the concentration of uranium has the typical characters of low temperature geochemical processes. Interlayer oxidized zone can be defined from the bedrock to horizon C under hypergene weathering by such parameters as chemical metamorphosing、index of chemical weathering and index of mineral chemical differentiation.(2)Major elements can be divided into sensitive group、 active、 weak active and inert groups according to chemical metamorphosing parameter and fractional migration potential. For major elements of multivalent in the active group( Fe_2O_3、 FeO) and U, the migration and concentration trend in interlayer oxidized zone is apparent.
