The study of Namurian Flora is not so well advanced because of the limited geographic distribution of the plants in the world, even the stage had been taken place by Serpukhovian and Bashkirian due to the middle borderline between Upper and Lower Carbeniferous passing through the ammonite subzone E2 and subzone H1 of Namurian A, thus there are not so many practical papers subjected to the plants of this stage like the other periods these years.

纳缪尔期植物群的研究工作因受到该期地层分布的局限性而不如其他地史时期植物群研究地深入，甚至由于纳缪尔阶A期菊石E_2与H_1亚带之间的界线亦是上下石炭统的分界线，所以在近年来的《国际地层表》中该阶名也逐渐被塞普霍夫阶和巴斯基尔阶所代替。

It is found that,through sliding zone soil mineral component and water-soil interaction analysis,the principle reason of landslide is that coal measure strata turves soil contains certain proportional hydrophilic mineral ,and its mechanical index will fall greatly after water-soil interaction.

以京珠高速粤境北段k18+170~k18+225滑坡为例，研究了煤系地层滑坡机理，通过对滑动带土的矿物组成及其物理力学性质分析，发现该类边坡滑坡的主要原因是煤系地层中的泥炭土含有一定比例的亲水矿物，在水的作用下力学性质发生大幅度降低。

The deposit of tungsten and the output of tungsten concentrate in Ganzhou, each take 30% that of total in China. Among them the deposit of high grade wolframite takes as much as 70% that of total in China and 60% in the world. So Ganzhou is called as "Tungsten capital of the world".

而赣南地层中钨的富集为世界地层钨平均值1.33ppm的7倍以上，高达9.53—12ppm，钨矿储量及钨精矿的产量均占全国30%，其中高品质黑钨保有储量占全国同类矿的70%，世界的60%；于是赣州，成为誉满五洲的"世界钨都"。

Based on the above research, we analyzed regional metallogenic conditions from geology, geophysics and geochemistry. Considering regional strata, some source beds with ore-bearing strata controlled apparently metallogenesis. The strata contained hydrothermal siliceous rock or siliceous albitite ether formed some favorable source beds and established substantial foundation for later diplogenetic metallogenesis e.g.

从区域地层上来看，含特殊层位的矿源层对成矿有明显的控制作用，其中含热水沉积成因的硅质岩或硅质钠长质岩的地层或形成有利的矿源岩，为后期叠生成矿奠定物质基础，或直接形成工业矿床；另外，区内黑色页岩（包括碳质板岩、碳质泥岩、碳质页岩和含碳钙质板岩等）也是很好的矿源层。

This rapid continuous inversion method utilize well logging curves to delaminate formation,and integrate auto-delaminate and human-computer interaction delamination to provide reliable initial model for iteration inversion calculation,and in the same time apply resistivity comparison and gamma as the constraint condition to reprocess the data from the inversion, all these improve the precision of this inversion and get the logical resistivity curves of both filter layer and impervious bed.

快速连续反演方法利用测井曲线划分地层，进行自动分层与人机交互分层相结合的方法，为迭代反演计算提供出可靠的初始模型，同时应用电阻率比值、自然伽玛作为约束条件对反演得到的数据进行约束后处理，提高反演的精度，得到合理的渗透层和非渗透层的电阻率曲线，并在理论地层模型和实际测井模型中均进行了测试。

On the basis of analysis of the movement characteristics of horizontal layered foundation and the relationship between soil parameters and eigenvalues and eigenvectors of the soil system, frequency domainid entification method of the layered foundation parameters is suggested by correcting the deviation between the measured soil data and theoretical calculation results.

在分析水平层状地基运动特征的基础上，通过研究地层系统的特征值和特征向量与地层参数之间的关系，修正测量得到的数据与理论计算结果之间的偏差，建立了层状地基参数的频域识别方法。

The strata between the carbonate rocks of the Chaguoluoma Formation (Devonian-Early Carboniferous) and carbonate rocks of the Xiala Formation consist mainly of clastic rocks with limestone, which are marked by glaciomarine deposits in terms of sedimentation and mixing of Gondwanan and Tethyan faunas in terms of fossils.

古生物群混生的现象为石炭纪—二叠纪的特提斯生物区与冈瓦纳生物区之间的地层和古生物对比建立了一座桥梁。永珠组中上部地层中同时产有牙形石和腕足类，牙形石的研究表明其时代为晚石炭世莫斯科期，而腕足类的研究则表明其为早二叠世萨克马尔期。

The course of heat conducting in the drills has a detailed analysis first time, and it's pointed out that the loss of heat energy can be decreased through the reduce of distance between heating resistant element and inner casing of the subterrene drills, and thickness of the shell.

钻进压力对钻进速度的影响与地层中的空隙和孔隙有关，即地层越松散，钻压的影响越大，可以与热熔器的热功率一样，采用比钻压的概念，即在热熔器单位横截面积上的钻压值。

The main body of the outcropping rock layer is composed of deep gray trachyte of Baitoushan formation of mid-Pleistocene series and yellow, brown yellow volcanic-tuff crust of weather. This kind of structure that weak layers and hard layers emerge alternately contributes to the instability of rock mass.

长白山一带出露的地层主体为中更新统白头山组深灰色粗面岩及黄色、褐黄色火山凝灰岩、火山灰风化壳，这种软硬相间的层状地层组合为岩体的失稳创造了条件，岩体失稳产生的堆积物为泥石流准备了充足的固体物质。
