On the basis of previous research works, new exploration wells, new appraisal wells and 3d seismic material are added to new research work in which rock and mineral, sedimentary facies and oil bearing characters are studied deeply by employing the methods of petroleum geology, sedimentary geology and reservoir geology. the results of reservoir prediction on fluvial sandbody in the upper of formation of guantao group obtained by using coherent analysis and acoustical impedance inversion bring good effect to the exploration and development of chengdao oilfield
本文在以往工作的基礎上，補充新鉆探井、評價井和三維地震資料，運用石油地質學、沉積地質學、儲層地質學等原理方法，對埕島油田主力含油層系館上段地層的巖礦、沉積相及油氣富集特徵進行了深入的研究，對館上段河流相砂體進行了以測井約束地震反演為主的儲層預測研究，研究成果為繼續開展埕島油田的勘探開發提供了重要依據。 -

The acceptability our rejection and the depiction of some content in the course " mechanisms and machine theory " is discussed, ( e. g., group dividing, solving steps of the graphical method for vector equation, versions and methods for analytical kinematic analysis, inversion design for linkage mechanisms, crank angle between the two limiting positions, design formulae for cam mechanisms, classification of combined mechanisms, formula of the radius of addendum circle of gear, balancing of machinery, etc. ) and some new opinions are presented
摘要就《機械原理》課程的某些內容（如：拆桿組的方法、矢量方程圖解法的解題步驟、運動分析解析法的版本和方法、連桿機構的反轉法設計、極位夾角、凸輪機構設計公式、組合機構的分類、齒輪齒頂圓半徑公式、機械的平衡等）的取捨和敘述進行探討，提出一些新的看法。 -
Our group has prepared nanometer - scale metal films in layer structures on glassy carbon ( gc ) substrate by cyclic voltammetric deposition. by using co as probe molecule, we have revealed for the first time, abnormal ir effects ( aires ) on these layer nanostructured films. the alres consists of several abnormal ir features including the enhancement of ir absorption, the inversion of ir band direction ( anti - absorption ), and the increase of fwhm ( increase of the number of different adsorption sites )
本研究小組採用電化學循環伏安電沉積法在gc基底上制備層狀納米結構金屬薄膜，以co作為分子探針，觀察到異常紅外效應（ aires ）光譜特徵，即co等探針分子發生紅外吸收增強、紅外譜峰方向倒反（反吸收）和譜峰變寬（振動能級離散程度增加） 。 -
