The thin layer of microbiotic crusts with lower bulk density, lower density, higher soil porosity and higher water-holding capacity will markedly influence the soil hydrological processes, such as the processes of penetration, the interception, the redistribution and the evaporation of precipitation, which will threat the soil-water environment in Shapotou area.

容重较小、比重低、孔隙度高和持水性能强的薄层微生物结皮对土壤水文过程产生了深刻的影响。在沙坡头地区，微生物结皮改变了降雨在沙丘土壤中的渗透、再分配、拦截和蒸发等过程，并最终导致固定沙丘土壤水环境的恶化。

Based on this idea, the author has chosen two typical loess sections of Luochuan, and Xifeng for this study, collected the successive loess columns; To probe the conditional experiments of BeO sample preparation and measurement, and improve the existing method; On the basis of the technology improvement, the author has finished 402 samples' BeO preparation and AMS measurement; Also at the same time, to separate quartz from samples at 1 cm interval for both Luochuan and Xifeng sections systematically, to carry out measurements of quartz grain-size, SUS, grey scale, carbonate content and bulk sample density; By using the grain size model, the author has set up the chronological framework for both Luochuan, and Xifeng sections and the time sequence of millennial scale abrupt climate events recorded in loess strata, and reconstructed the East Asian monsoon history over 130ka by using multi proxies; Finally, to discuss the possible mechanisms of palaeoclimatic changes tentatively.

详细地球科学的发展离不开高精度和高分辨率的研究。运用长寿命核素如〓Be作为环境过程的示踪，已成为不可替代的有效工具。本论文选择洛川、西峰两个典型的黄土剖面，连续采集柱状样；探索了BeO样品制备、测量的条件实验，改进了原有的方法，完成了402个BeO样品的制备和AMS测量；同时还系统地分离洛川、西峰剖面高分辨率（1cm）黄土、古土壤样品中的碎屑石英，测量了碎屑石英粒度，以及全样的磁化率、灰度、碳酸盐含量和容重等古气候代用指标；采用粒度年代模式建立了洛川剖面和西峰剖面的年代标尺，建立了黄土地层记录的千年尺度的气候突变事件的时间序列，多指标重建了最近130ka东亚季风变迁史；初步讨论了古气候变迁的可能机制。

Finally, the forming and localization course of shear band of tungsten alloy material have been analyzed. The influence of thermodynamics parameter of density, static yield stress, specific heat coefficient and heat conducted coefficient on shear-localized of tungsten alloy has been contrastively and individually analyzed through changing magnitude of each parameter. The result has shown that static yield stress and specific heat coefficient have bigger influence on the shear-localized of tungsten alloy.

最后对钨合金材料中的剪切带的形成和局部化过程进行了分析，并且在分别改变密度、静态屈服应力、比热容及热导率等热力学参数下，对比分析了它们对钨合金剪切局部化的影响程度，结果表明改变静态屈服应力和比热容对钨合金剪切局部化的影响较大。

In order to optimize the design of hot blast stove, a model of heat transfer in chamber of hot blast stove was developed and the software based on the model was established. The effect of the checker thermal characteristics such as thermal conductivity, heat capacity, density etc on the temperature of blast and checkers,the heat accumulation and heat release of checkers was determined.

为优化热风炉设计，建立了热风炉蓄热室内传热过程的数学模型，制作了应用程序软件，探讨了不同的格子砖物性参数，如导热系数、比热容和密度等对格子砖温度场分布、气体温度分布以及格子砖蓄热量和放热量的影响。

In this paper, the upper member of Eh〓, Shuanghe ～ Zhaoao area, Biyang basin, is treated as a case to study outer and iuner configuration of terrigenous sequence, based on the synthetical analysis of seismic, core, welllog and geological data. Using computer simulation technique of quantitative sequence stratigraphy, accommodation diagram, and baselevel analysis theory, the controling factors. formation, and procedure-responsed mechanics of terrigenous sequence are discussed.

文中以双河～赵凹地区下第三系核三〓段为例，综合利用地震、钻井、测井、地质等资料，剖析了泌阳断陷陆相层序外部构型和内部构型；采用定量层序地层学计算机模拟技术、可容空间图解方法及沉积基准面分析原理，探讨了泌阳断陷陆相层序控制因素、形成机理及其过程—响应机制。
