摘要通過對世界上壓扭性盆地的成盆機制、演化模式和油氣地質特點分析，總結壓扭性盆地具有6個方面的石油地質特徵：壓扭作用期間盆地的沉積速率較高，一般形成較厚的粗碎屑沉積，它們常構成很好的油氣儲集層：盆地的烴源巖往住來自於前壓扭期砂成的富含有機質的巖石，但在強烈的壓扭作用期間，在沖斷帶的前緣深坳陷（前淵）中有可能發育深水半深水相的烴源巖；壓扭（張扭）作用期間形成的雁行式褶皺（包括背斜和斷鼻等）往住是很好的油氣圈閉；壓扭作用易於成藏；壓扭作用可以促進有機質的成熟生烴作用；壓扭性盆地的周邊沖斷帶是油氣賦存的有利部位。During my master " degree investigation, i mainly focused on the coarse - grain stratigraphy within mesozoic basins in chengde and pingquan districts, the eastern yanshan, and did systemic provenance analysis and paleo - current direction measurement and studied the relationship among basin evolution, volcanism and tectonism. then i summarized the mesozoic basin development and the coupling characters of basin and mountain. the evolution of basin and mountain in this area can be divided into several stages : the stage of compression uplift and flexural basin during the triassic through the early jurassic, the stage of structural compression - volcanism and foreland basin during the middle and late jurassic and the stage of rift basin in the cretaceous
在野外典型路線調查的基礎上，對燕山地區東段承德、平泉地區的中生代盆地中發育的粗碎屑沉積層，進行了系統的物源分析與古流測定，並在此基礎上重點剖析了盆地的發育、火山活動、構造變動三者之間的關系，總結了本區中生代盆地發育規律及盆山耦合特徵，並將盆山演化劃分為：三疊紀?早侏羅紀的構造擠壓隆升與撓曲盆地發育階段階段，中晚侏羅紀的構造擠壓?火山活動與類前陸盆地發育階段，早白堊世的拉張斷陷盆地發育階段。The results are as follows : ( 1 ) bst thin film prepared by pulsed laser deposition is well crystallized. the average grain size is 100nm and the surface roughness is about 10nm. when the electric field intensity is 3v /, the tunability of the thin film is about 30 % and the loss tangent is about 20 % under room temperature
研究結果如下： （ 1 ）採用脈沖激光沉積法制備的bst薄膜結晶良好，晶粒尺寸在100左右；表面粗糙度約為10 ；室溫下，當直流電場為3v /時介電系數變化率約為30 % ，介質損耗約為20 % 。In a way, the evolution to upward of distributary channel microlithofacies in shelf delta plain of later carboniferous epoch in this area is repeatedly and rapidly, and every time is a normal grading change from coarse to thin, at last it evolve into marshy deposit
應用馬爾柯夫鏈分析方法得到的結果是，本區石炭統上段礫石質三角洲平原分支流河道的微巖相旋迴的向上演化，是重復而迅速的，每次都是由粗到細的正旋迴，最後演化為沼澤沉積。3. at the vertical direction of the section, the grain - size distributional coarse and fine rhythms vary very pronouncedly with the alternation of sedimentary facies, which is clearly shown not only in the grain - size percentage in this section but also in the response from different grain - size parameters
在剖面的垂直方向，粒度的粗細韻律分佈隨沉積相的變化非常明顯。這不僅在剖面上粒度的百分含量可以清楚地反映出來，且各個粒度參數也同樣具有顯著響應。Typical temperature is 800 - 1000 in cvd diamond process, while the high temperature limits its application in optical window and coating such as gaas, zns etc. low temperature can not only make diamond crystal nucleus finer, reduce surface roughness of diamond films and lessen light dispersion, but also eliminate thermal stress
化學氣相沉積金剛石膜過程中，襯底的典型溫度為800 1000 ，這么高的溫度限制了其作為gaas 、 zns等低熔點光學材料窗口和塗層的應用。低溫沉積金剛石膜不僅可以使晶粒細化，降低表面粗糙度，減小光的散射作用，而且可以消除熱應力。( 6 ) the study of electroplating ni ~ co coating on silica fiber showed that a special pretreatment must be preformed before electroless nickel because of the smooth surface of silica fiber. ( 7 ) a ni - co coating was acquired by means of eletroless and electroplating
