After the operation of the Three Georges Project,change the water and sand arrive condition of the lower reaches riverway of the reservoir, the lower reaches riverway of the dam erode long time and long distance.

认真翻译很少的话认真给分！！1三峡工程蓄水运用后，改变了水库下游河道的来水来沙条件，坝下游河道发生长历时长河段的冲刷。

After operating the method of storing clear water and discharging muddy water in Sanmenxia Reservoir, the main reason for erosion and deposit in riverway is the change of running water level in flood season .

三门峡水库蓄清排浑运行以来，决定潼关以下库区河道冲淤主要是水库运行水位的高低，汛期水库运行水位的高低对潼关高程的升降起着主要的作用，因此汛期潼关高程的变化主要由水库运行水位决定的。

By performing core displacement and micro pore model displacement experiments, the mechanism and changing law of saliferous reservoir parameters were studied.

通过岩心驱替以及砂岩微观孔隙模型驱替实验，研究了高含盐油藏水驱储层参数变化机理和规律。

The result shows that the changing law of saliferous reservoir parameters is a nonlinear relationship with several variables, and it is a very complicated process.

研究结果表明，高含盐油藏储层参数变化呈多元非线性函数关系，变化规律复杂；渗透率变化存在临界值，大于临界值时，渗透率随着驱替速度、驱替量和含盐量的增加而增大，小于临界值时，渗透率随着驱替速度、驱替量和含盐量的增加而减小；注入水性质会对参数变化过程有影响，而对最终变化结果无影响；盐的溶解是储层参数变化的根本原因，岩石颗粒的脱落和运移是储层参数变化的直接原因。

Based on PVT and sand packed tube, the high pressure characteristics such as viscosity, expansion coefficient and minimum miscibility pressure were measured for mixture of crude oil and carbon dioxide, and the oil and gas production during multi contact experiments under constant and declined pressure was investigated, Lastly, the production performance of sand packed tube similar to low permeable reservoir.

通过PVT筒和填砂管气液平衡等模拟实验，测定原油与CO2体系的黏度、膨胀因数和最小混相压力等高压物性参数，研究了恒压和降压下5次CO2接触过程中原油和气体的产量变化，并对比研究模拟特低渗填砂管与PVT筒CO2吞吐实验的开采动态。

At the same time of changing watershed intrinsic natural relation, people destroyed its crude system. Watershed is faced with more and more serious crisis in water environment and water lack, which result in water quality worsened, more sandiness, reservoir silted.

人类改变流域原有的自然联系的同时，也破坏了流域天然系统，使流域面临着愈演愈烈的水生态环境危机和严重的水资源短缺问题，从而导致流域上游水质恶化，河流含沙量加大，中下游水库淤积严重。

This paper has guidance to acidizing design of sandstone reservoir.

对于砂岩油藏的酸化设计具有一定的指导作用。

Some problem in development are discussed, and some new knowledge about development of low permeability sandstone reservoir are offered, and some

发中的某些问题，以期为该类油藏的合理开发提供参考。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
