拉伸區域
英文
tensile region-
Chagan sag is a secondary tectonic unit in chagandelesu depression, northeastern yingen - eji ' naqi basin, and the basement of the basin is a paleozoic fold belt of continental margin or island arc at the connection region of north china plate * tarim plate and kazakstan plate, with the character of erogenic belt. in working area and its adjacent area, the forming tectonic setting of indosinian intrusion was that orogenic belt pressed strongly, intracontinental subduction ; that of early yanshan movement epoch was the stress field transferred from compression to extension meanwhile the incrassate crust of orogenic zone turned to extensional collapse ; and that of early cretaceous volcanics was that the area structure extensional collapse further more during the post period of orogenic phase
查干凹陷屬于銀根?額濟納旗盆地東北端查干德勒蘇坳陷內的一個次級構造單元，其盆地基底為古生代時期華北板塊、哈薩克斯坦板塊和塔里木板塊交接部位形成的陸緣或島弧褶皺帶，具有古生代造山帶的性質。研究區及鄰區印支期侵入巖形成於造山帶強烈擠壓陸內俯沖的構造環境；燕山早期侵入巖形成於由擠壓轉向拉伸、造山帶的增厚陸殼開始發生伸展垮塌的構造環境；早白堊世火山巖形成於造山期后進一步發生伸展垮塌的區域構造環境。Thus, the paper focuses on mineralogy, petrology, petrogeochemistry, isotopic chorology, and sr - nd - pb isotopes of the mafic intrusions and dikes in fujian province, se china. in addition, we also discussed the process of the plate subduction, mantle evolution, crust - mantle interaction, lithospheric thinning and extension, and the reaction for crustal extensi on in fujian province, se china. ( 1 ) daiqianshan mafic intrusion is situated along the changle - nanao fault, which intruded in the metamorphic rocks
基於此，本文以中國東南部福建省的基性脈巖、巖體為研究對象，運用系統的礦物學、巖石學、巖石地球化學、同位素地球化學及同位素年代學證據，詳細論述了晚中生代中國東南部板塊俯沖、地幔演化、殼幔相互作用及巖石圈伸展減薄的地球動力學過程，探討了地殼拉張期次在福建省區域構造上的響應。A large amount of data of the latest regional geoglogy and the latest correlation data of layers and rock formation have been quoted, and a description of distribution of crystalline basement, formation, evolution as well as the distribution characteristic of the fracture belt of ordos basin have been made in this paper, and the paper also pointed out that the g - layer which lies between the base of the basin and tg reflector, is the extension of basinward of guandaokou of jixian system. the layer of changcheng system and jixian system, which had been divided before, can be correlated with the exposed huangqikou group and wangquankou group in helan mountain, and divided into qingbaikou system. so, the paper denied the viewpoint of the existence of aulacogen in hutuo period and middle proterozoic in this basin
文中引用了大量最新的區域地質資料和最新的地層、巖系劃分對比資料，對鄂爾多斯盆地結晶基底的巖系分佈、形成、演化以及斷裂的展布特徵進行了描繪，並指出盆地基底與tg反射層之間的g層是薊縣系官道口群向盆地的延伸，盆地中原劃分的長城系、薊縣系地層可以和賀蘭山出露的黃旗口組、王全口組對比，亦劃歸青白口系，從而否定了鄂爾多斯盆地存在滹沱期坳拉谷和盆地中有中元古坳拉谷發育階段的看法。The a phase can change to b phase by stretching. in the range of low temperature the higher content of b crystalline was achieved during the higher drawing ratio and the higher drawing temperature
拉伸有利於pvdf纖維的相結晶向相結晶轉變，且拉伸倍數越高相含量越高；較低溫度區域內（ 100 ） ，溫度提高有利於相結晶向相轉變，較高溫度區域內（ 100 ） ，溫度提高對相向相轉變作用不大。Secondly, we prove that the above conclusion is also true for the boundary correspondence of afbne str
然後，對于拋物區域與雙曲區域上仿射拉伸的邊界對應，通過計算，證明上述結論也成立。If there are high temperature gradient between cool liner and hot liner, compressive plastic strain appear at that transient time, which lead to gas film wall bearing high tensile stress at high temperature. high tensile stress is one of main reasons which destroy combustor
分析表明，起動過程中由於熱傳導滯后引發的溫度梯度可以導致火焰筒氣膜唇邊在起動瞬間發生較大的壓縮塑性應變，進而使得該區域在工作時承受較高水平的拉伸應力，高的拉應力會導致火焰筒萌生裂紋。Since the sheet metal in the wall area is relatively unsupported by the tool, the elimination of wall wrinkles is more difficult than the suppression of flange wrinkles
由於金屬板料在拉伸壁區域內相對無支撐，因此消除拉伸壁起皺比抑製法蘭邊起皺要難得多。It is well known that additional stretching of the material in the unsupported wall area may prevent wrinkling, and this can be achieved in practice by increasing the blank - holder force ; but the application of excessive tensile stresses leads to failure by tearing
我們知道在不被支撐的拉伸壁區域中材料的外力拉伸可以防止起皺，這可以在實踐中通過增加壓邊力而實現，但是運用過大的拉伸力會引起破裂失效。分享友人
