地层

Now, importantly, elsewhere includes the Lower Cambrian in China.

现在，重要的是，其他地方也包括了中国的下寒武统地层。

Especially before the Cambrian stratum, a typical development, has become the country's comparative study of key areas.

特别是前寒武系地层，发育典型，已经成为全国研究对比的重点地区。

The study indicates that the optimum windows width decides the layering precision, interface partition with sym6 wavelet is better than with db4, canonical wavelet decomposition of conventional logging curves can well meet the demand of coenocorrelation.

研究表明，选择恰当窗宽小波决定测井曲线小波分层精度、测井数据sym6小波分解的小层界面划分效果要稍好于db4小波、常规测井曲线正则性小波分解可以很好地满足高分辨率层序地层划分要求。

The term is used at various localities in North Africa, includes beds ranging from carboniferous to Early Cretaceous

在北非不同的地方使用这个名称，包括从石炭纪到早白垩纪的地层。

The term is used at various localities in North Africa, in cludes beds rang in g from carboniferous to Early Cretaceous

在北非不同的地方使用这个名称，包括从石炭纪到早白垩纪的地层。

Although there is a little carbonite caused by some magmatic dikes in the CarboniferousPermiam coal, most Carboniferous-Permian coal has no great differences in vitrinite reflectance, crystalline indices, bulk specific gravity, hardness, and the content of velotile matter from the Jurassic coal, and both are super-anthracite.

区内石炭—二叠系煤与侏罗系煤除了前者含有一些由侵入体造成的天然焦或半焦外，二者均为超无烟煤，在镜质体反射率、煤晶核结构、显微硬度、挥发份和容重等方面上均没有明显的差异，说明区域变质是在煤系地层沉积之后发生的。

Hot washing by moving hot washing truck and hollow sucker rod is efficient, less in washing fluid , no formation contaminant, no casinghead gas release. It adapts oil wells with low reservoir pressure and deep depth of plunger and serious paraffin problem.

活动热洗车配合空心抽油杆热洗清蜡热效率高、洗井液少、不伤害油层、不用放套气，适合于地层压力低、下泵深度较深、结蜡严重、常规洗井困难的油井。

Excessive formation back pressure may be due to limited or plugged perforations; subsurface or surface chokes; undersized gas-oil separator, flowlines, tubing, or casing; or excessive back pressure on flowline, casinghead gas gathering system, or gasoil separator.

183u 译文：过高的地层回压也许是由于有限的或堵塞的射孔孔眼；井下或地面油嘴；尺寸不足的气液分离器，流动管线，油管或套管；流动管线，套管头气体集输管线或气，油分离器上过高的回压。

This paper firstly made a brief review about Catastrophism Gradualismand Neocatastrophism in Geology and then did some researcles on event stratigraphy s formation, development, therotical essence and its importance in earth sciences.

根据近年来有关研究新进展，概括地评述了地质灾变论、渐变论、新灾变论及事件地层学的形成、发展、理论实质及其在地球科学理论与实践中的重大现实意义。

Ore source of celestite mineralization system is complex in this area. Weathering and erosion of the floor of the basin and the mountain around the basin, evaporite sediment in the earlier, deep water, Mesozoic and Cenozoic volcanism can provide the strontium. In particular, serving as initial ore source, oil-field brine supplies the majority of strontium.

该区矿源场分析表明，锶的来源有基底和周边山系风化剥蚀来源、老含盐地层补给、深部水和中、新生代火山活动补给；其中，盆地基底和周边老山风化以及深部水补给为主要来源，特别是油田水作为矿源层为锶矿床的形成提供了大量锶源。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
