Based on the studies of petrotexture, structural deformation and the relevant metamorphism, this paper indicates that this peridotite massif is the product of ultramafic magma cumulated at the crust - mantle transtion zone and has undergone the early stage of plastic deformation under the condition of granulite facies ( 800 ) and late ductile shearing at amphibolite and greenschist facies in relevance to uplifting
本文通過巖體的結構、構造變形及相應的變質作用研究,提出了該橄欖巖體是由超基性巖漿在殼幔過渡帶結晶而成,並經歷了與圍巖一致的麻粒巖相( 800 )條件下的早期塑性變形以及角閃巖相和綠片巖相退化變質條件下與逆沖上升有關的韌性剪切變形。The comparison study of the three belts indicates although they are distinct from each other all the three belts show many common features in the aspect of the metallogeny of large - rich vein uranium deposits, i. e : the important metallogenic areas are located above the old crystalline basement ; the paleo - rifting ( taphrogeny ) controls the development of the volcanic belt and at the same time it is favourable metallogenic tectonic environment ; the occurrence of uranium deposit does not depend on the lithology of volcanic rocks ; uranium metallogeny is obviously constrained by deep geologic processes and the connected fault - structural net is the necessary condition for the formation of large - rich uranium deposits
對比研究表明,雖然它們各具特色,就脈型富大鈾礦床成礦作用而言,它們又具有較多的共性:重要成礦區的火山噴發皆奠基在古老的結晶基底上;古裂谷(或裂陷)既控制了火山巖帶的發育,又是有利的成礦構造背景;鈾礦賦存對火山巖的巖性沒有明顯的選擇性;鈾成礦的深部控製作用明顯;聯通的構造網路系統是形成富大鈾礦的必要條件。A patch antenna with air holes in the substrate has been designed. the finite - difference time - domain ( fdtd ) method together with the perfectly matched layer ( pml ) boundary treatment has been used to study the performance of the antenna. it is shown that the surface waves are significiently suppressed, the frequency bandwidth is improved, the sidelobe levels are reduced and consequently the gain in the forward direction is improved by 14 db ( about 4 db higher than the value reported previously )
設計了一種基底鉆周期圓孔結構的電磁(光子)晶體貼片天線,用fdtd方法並結合pml吸收邊界條件對該天線進行了研究,結果表明本文所設計的基底鉆孔型電磁晶體貼片天線取得了多方面的性能改善,與普通天線相比,基底中的表面波受到很大抑制,天線的帶寬增加,遠場方向圖上天線的旁瓣和背瓣被明顯削弱,向前輻射的增益由原來的12db增加到26db ,增加了14db ,比文獻上報道的gonzalo等人的研究結果提高了4db 。6. on the ground of all these research works, we studied the magma crystallization - assimilationary mechanism that works on the shandong sapphire and its bands, we also analysed the relationship between this mechanism and the isolated or open condition
6 、在上述研究基礎上,討論了山東昌樂藍寶石及其環帶形成的巖漿結晶-同化混染聯合作用機制及其與封閉開放條件的關系。分享友人
