花岗岩风化壳剖面适用六分法（残积土层、全风化带、强风化带、中等风化带、微风化带和未风化带）。

By an analysis of the sporopllen time sequences from samples of 38 sections, a discussion of the vegetational and environmental megaevolution in China during the time of 1.6MaBP ～0.8MaBP was made,with the result that we have 2 zones of the sporopollen assemblages and 2 palynoclimate events.

摘 要：通过对已有38个剖面的孢粉时间序列分析，探讨了1.6MaBP～0.8MaBP的植被与环境巨变，划分出两个孢粉带及两个孢粉气候事件，提出该时段是更新世环境最恶劣的时期。

In the two test sites, the soil water movement numerical models of vertical-one-dimension and cross section two-dimension have been established with the softwarer Vadose/W and self-programming code, of which the advantage is that it can deals with lower boundary and the upper boundary (such as meteorologic, vegetational, etc) conditions in convenience. The fitting between the model and observation data from sites indicates that the models are relatively high precision. So the models can be used to study problems such as soil evaporation, infiltration to recharge groundwater and so on under various conditions.

运用包气带水分运移软件Vadose/W和自编程序，建立了两个试验场垂向一维和剖面二维土壤水运移模型，该模型的优势在于可灵活地处理下边界和上边界条件，试验场观测数据拟合表明模型精度较高，可用于研究各种条件下土壤蒸发、土壤水分下渗补给地下水等问题。

Based on palynological records of the Qangzê section in Zanda basin, Ngari, Tibet, the authors have preliminarily defined the Neogene-Quaternary boundary in the area and revealed the vegetational and environmental history of the area since the late Pleistocene.

摘 要：通过对西藏阿里札达盆地香孜剖面的孢粉分析，初步定出该地区新近纪和第四纪的界线，并得到更新世晚期以来该地区植被与环境发展的历史。

Therefore, local wave decomposition technology was introduced into the logging date extrapolation method constrained by time-phase model to gain the seismic instantaneous phase. The relationship of logging and seismic data was established through the wellside strata correlation. High resolution attributes inversion profiles were generated through the extrapolation of logging constrained by equiphase surface established based on seismic data.

为此，在时间－相位模型约束的井资料外推方法中，引入局域波分解技术来求解地震瞬时相位；通过井旁地层对比，建立测井资料与地震资料之间的联系，把测并信息在地震资料建立的等相面约束下外推出去，以获得高分辨率的属性反演剖面。

SUMMARY A more accurate steady drillstring tension-torque model has been established by taking into account of drillstring, wellbore condition , drilling operation and drilling parameters. This model has been used in scientific calculations of directional and horizontal wells, such as determing the friction factor between wellbore and drillstring, calculating the hook load and rotating torque, ckecking the strength and stability of drillstring, optimizing well trajectory, computing the WOB while drilling by downhole motor and predioting the maxinum allowable length of horizontal section.

综合考虑钻柱、井眼环境、作业过程和作业参数的影响，建立了更完善的钻柱稳态拉力和扭矩模型，并将其应用于确定钻柱与井壁的摩擦系数、计算大钩负荷和转盘扭矩、校核钻柱的强度和稳定性、优选井眼剖面、推算井下动力钻进的实际钻压和预测水平井段的最大可钻长度等定向水平井的科学计算中。

The contents of MBC decreased with the increasing of soil depth.

从垂直剖面分布来看，微生物量碳含量总体变化趋势是随着土层深度的增加而逐渐减少。

MicroloG logging has high longitudinal resolution and reliable division of thin interheddings and interlinings. It is a indispensable in sand mudstone profile combination logging.

微电极测井曲线的纵向分辨能力强，划分薄互层和薄夹层比较可靠，是砂泥岩剖面组合测井中不可缺少的测井方法。

The high-grade metamorphic terrain of Hengshan located at the hinderland of North China Carton in northern part of Shanxi province, China, is a middle-lower crustal transition area of the typical continental crustal profiles of the Wutaishan—Hengshan—Datong—Jining of the early Precambrian etamorphic terrain in China.The Hengshan gneisses of the amphibolite—granulite facieses metamorphic terrain consist of the TTG gneisses and the horizontal adding mantle materials. The Supracrustal rocks in this area are composed of the mafic volcanic rocks and sedimentary rocks. The plenty of granitoid magma activities are the result of anatexes.
