Furthermore, we define a convolution multiplication between characteristic functions of constructible subsets by using push-forward functor from the category of algebraic varieties over C to the category of spaces of constructible functions. We construct geometric model for "intrinsic symmetry" of the octahedral axiom in a triangulated category. Using it, we deduce the multiplication satisfies the Jacobi identity of Lie algebra and then realize infinite dimensional Lie algebras.

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.

And tell you the principle concerning bike,we can learn how and when it was invented and its basic structure as well from the passage.we got the history of bike and when it become popular,these are really interesting.although we usually ride bike around,we're not familiar with the history and the basic structure of it.after learning the unit,it give me a fresh knowledge of bike,and also tell us commonsensibles like how to forbit downdipping while riding in muddinesses and so on.it's a great help for us.because why don't learn more to keep our bikes more safe?
而且从文章告诉我们自行车是怎么样发明的?什么时候发明的?它的构造又是怎么样的?让我们了解了自行车的历史。以及它是什么时候开始流行的。这些都相当有意思。虽然平时我们经常骑脚踏车,可对他的历史来源和它的简单构造也不是很清楚,但学了这单元之后,使我对脚踏车又有了一个新的认识。而且它还告诉我们,当我们骑在泥泞的地面时,怎么样避免下沉?等等一些常识性的问题,可以让我们在现实生活中运用到,这是起着很大作用的,因为多点了解就能让自己的行车得到更好的安全保证。何乐而不为呢?

Analyzing the model, especially the activity of Taihang Mountain piedmont fault, we got such main conclusion:1. Based on sequence stratigraphy, the strata is divided from the selected drills. And the Quaternary stratigraphic framework of Handan city is established, dividing the Quaternary strata into four parts- Qh, Qp3O , Qp2Y and Qp1G.2. With all the selected drill data of Handan city, a drill database is established. A quaternary strata 3D model of Handan city is imitated by GOCAD and ArcGIS, and so are the bottom structural map of each horizon.3. Analyzing the 3D model and the contradistinction section of drills, we got: the stratum of Qh and Qp3 is smooth and flat, with a feature of a higher west, little difference between south and north and undistinctness of faults; there are several depocenters along S-N and N-W in the stratum of Qp2, and the evolution of the stratum is controlled by a couple of ruptures, which means the tectonic movement is active in this period of time.4. Since quaternary, main tectonic movements happened in Qp2 and have been stable in Qp3 and Qh.
获得主要结论如下:1、利用层序地层学的方法将收集的邯郸市钻孔以及论文所依托项目野外施工的钻孔进行了具体的地层划分与对比,建立了邯郸市第四系等时地层格架,将邯郸市第四系划分为全新统、更新统上部欧庄组(Qp3O)、更新统中部杨柳青组(Qp2Y)和更新统下部固安组(Qp1G)。2、利用收集到的邯郸市水文、工勘钻孔以及所依托项目初勘和详勘两个阶段野外施工的钻孔数据,建立钻孔数据库,通过使用三维建模软件GOCAD和地理信息系统软件ArcGIS等进行模拟,得到邯郸市市区部分第四系地层三维可视化模型,并获得各个地层的底部构造图;3、通过对所天生模型和钻孔廊带对比剖面的分析,可以得到:全新世和更新世晚期(Qp3)时期地形整体较平缓,整体上显示西高东低、南北差异不大的格式,断裂显示不明显;更新世中期(Qp2)时期沿南北向和北西向存在几个沉积中心,地层发育受几条断裂的控制,反映了研究区的构造活动在更新世中期较为活跃;4、邯郸市自第四系以来,主要构造运动均发生于更新世中期,到更新世晚期及全新世时期逐渐趋于稳定,进而使更新统上部和全新统地层沉积均一且完好。

Connecting sand body migration systems may controls the forming of oil-gas reservoir due to bottom bed overlap. lithologic pinch out, and/or the fault barrier. The migration system consisting of unconfornfity surface, sand bodyunconformity surface, and/or unconformity surface-fault, may control the forming of the bedrock weathered crust type oil-gas reservoir. The migration system consists of fault, sand body-fault, and/or sand body-unconformity surface, may control formation of oil-gas reservoir due to fault block, anticline, structure-lithologic, and/or fault-lithology.
