It is further pointed out that simulation experiments combined with geology , petrology , geochemistry and geophysics ( especially for high resolution seismic technique ) in studying mantle ( hotspot ) - ridge interaction will play an important role in such reseaches as plume - ridge interactions 在肯定地幔柱假说的基础上，对洋脊地幔柱（热点）的模拟实验以及三大洋中不同扩张脊与热点相互作用的最新研究作了系统的介绍和评述，指出室内模拟实验以及地质学、岩石学、地球化学和地球物理学（特别是高分辨率的地震技术）的结合研究将是本领域研究的发展趋势。
The results show that some factors , such as cation concentration , accompanying cation , flow rate , have significant effects on the diffusion of cation through clay . on the basis of the aforementioned tests , influences of the geoenvironmental characteristics of clay on the effectiveness of clay liners are analyzed in this thesis 本文还通过室内模拟试验研究了污染物在粘土中扩散的试验方法和影响因素，并发现水头的存在对污染物离子在粘土中的扩散具有明显的促进作用，不利于填埋场衬垫的防污性能。
To offer the scientific bases for tracking the n2o sources and sinks processes well and reducing soil n2o discharge flux , effects of the farming practice of clear plastic film mulch on the changes of soil nao discharge flux in the winter wheat field in shannxi guanzhong area were studied by field and incubation experiments 在此前提下，本丈通过田间和室内模拟试验，研究了陕西关中地膜覆盖的农作措施对冬小麦田土壤中n _ 2o排放通量的影响，旨在为大气中n _ 2o源汇的探索研究和土壤中n _ 2o的农业减排措施的研究提供科学的依据。
On the basis of construction technique of large diameter bored hollow pile of prestressing force concrete , through simulation test , this paper simulates the interaction of pile with side mediator and pile with end mediator respectively under different conditions of injected cement paste , analyses the changing regularity of ultimate skin friction in different depths and different mediators , and also studies the changing regularity of end resistance in different end mediators 本文在对大直径钻埋预应力混凝土空心桩的施工工艺分析研究的基础上，通过室内模拟试验，分别模拟桩与桩侧、桩端介质不同注浆情况下的相互作用性状，分析了桩侧介质变化时不同深度处桩侧极限摩阻力的变化规律和桩端介质变化时桩端承载力的变化规律。
( 2 ) the results of the rainfall - affected runoff scouring experiments in lab . when the rainfall intensity was less than l . omm / min , the soil erosion caused by the combination of rainfall and the upslope runoff was more than that caused by only the simulated rainfall . when the rainfall intensity was more than 2 . 0mm / min , the upslope runoff strengthened the effect of the runoff yielded in the local area on the dyke slope surface , and the effect increased with an increase of rainfall intensity 2 、室内模拟降雨+放水冲刷试验结果雨强小(如i 1 . 0mm min )时，上游注入水量对戗坡侵蚀作用比降雨在戗坡上所产生径流的侵蚀大；雨强大时( i 2 . 0mm min ) ，上游水量下泄与当地降雨径流一起增强对戗坡面的侵蚀作用，雨强越大，侵蚀作用也越大。
