The regularity of accumulation distribution is ascertained and directs the exploration orientation. the main results obtained in this paper are : 1. the analyses of hydrocarbon - bearing rock, reservoir, caprock and oil & gas reservoir indicate the source of oil & gas, the space for reservoir, requirement for preservation, reservoir type and its basic characters. 2. it is realized by the analyses of sealing up capability of caprock and faults, and fault ' slatter stability from microcosmic and macroscopic that the wide - spread regional caprock of nm t prevented oil & gas of neogene from diffusing fault movement in neogene less violated and fault displacement decreased, which are advantageous for the preservation of oil & gas reservoir. and latter structure movement usually formed the accunulation of oil & gas in neogene. 3. the research of history of hydrocarbon generation and expulsion of main hydrocarbon - bearing rock in qikou depression reveals the threshold depth and the fime of hydrocarbon generation and expulsion
項目研究取得了如下認識： 1 、對烴源巖、儲集層、蓋層及油氣藏展開分析，明確了歧口凹陷上第三系油氣藏的油氣來源、儲集場所、保存條件和油氣藏類型及其基本特徵； 2 、從微觀和宏觀上對蓋層的封蓋能力以及斷層封堵和後期穩定性進行分析，認識到明下段區域蓋層的廣泛分佈阻止了上第三系油氣藏的油氣逸散，同時上第三系斷層活動減弱，斷距較小，對油氣藏的保存較為有利。 -
The probability of being or exceeding a given damage state of buildings by a given ground motion intensity is calculated from the spectral displacement corresponding to the intersecting point of the demand spectrum and the capacity curve, the median value of spectral displacement at which the building reaches the threshold of the damage state and the standard deviation of natural logarithm of spectral displacement of the damage state
文中，討論了非彈性需求譜的推算，將現行抗震設計規范中規定的反應譜換算得到的彈性需求按對應的譜位移折減，得到非彈性需求譜。依對應的譜位移在四個需求譜上的四個點和原點，構造了典型建築物的抗力曲線。 -
Then the de - lay differential method of detecting the milling cutter breakage is put forward according to the above research work and the changing characteristics of power signal and vibration displacement signal when the tool breakage occurs, the monitoring stategy of sensors fusion based on the artificial neural network is put forward. the monitoring system of milling cutter breakage based on the information fusion of the power signal and vibration displace - ment signal has been developed. the diff culty in giving a dectecting threshold due to the changeable character of character of cutting condition has been solved, and a good reliability is ensured over a wide range of conditions
在上述研究工作的基礎上，提出了基於人工神經網路用於多傳感器信息融合的監測策略，開發研製了以機床主電機功率信號和主軸振動位移信號特徵參量融合的銑刀破損監測實驗系統，解決了銑削過程中切削條件多變導致監測閾值難以設置的難題，保證了在較寬的工作范圍內具有較高的識別準確率。
