Benthic foraminifer fauna, ams14c dating and acoustic sub - bottom profile was analyzed in the core ey02 - 2 and ey02 - 1 drilled from the muddy deposit in the middle southern yellow sea and the mid - shelf of north east china sea. considering the results of core qc2 ? dz4 and the standard oxygen isotope curves, we discussed the late - quaterenary paleo - environment evolution, benthic foraminifer fauna, paleo - climate, the climate events and water mass in postglacial period, average sedimentation rates, paleo - water depth, origin of sediments, average sea level rise rate in the shelf of south yellow sea and east china sea. at last we discussed the condition of sea level rise in the east china, green house effect and the protection of coastal zone
本文根據南黃海中部泥質區和東海中陸架的兩個鉆孔巖芯的古生物、 ams ~ （ 14 ） c測年、淺地層剖面等，參考qc _ 2 、 dz _ 4成果及標準氧同位素曲線探討了黃東海陸架晚第四紀古環境演化、底棲動物群特徵、古氣候、冰後期以來氣候事件、古水團、沉積速率、古水深、沉積物源、海平面平均上升率，討論目前中國東部海平面上升的狀況、溫室效應及海岸帶保護。Surrounding these special problems met in gas hydrates exploration and through study of high - precision magnetic survey, the sea test by r / v haiyang 1y that is owned by guangzhou marine geological survey in dongsha area of the south china sea, systematical analysis of the test result and combination interpretation of magnetic survey with seismic profile, the authors successfully employ the method to recognize the truth or false of the diapir in seismic profile by integrating total field of high - precision marine magnetic measurement with its gradient change
本文就目前天然氣水合物調查中存在的這些特殊技術問題，通過對海上高精度磁力測量技術方法研究、廣州海洋地質調查局「海洋四號」船在南海北部東沙海域的海上試驗、對試驗結果的系統研究分析以及磁測和地震剖面兩種手段的綜合解釋，成功地嘗試了用高精度海洋磁測成果中的磁力總場和梯度變化特徵來識別水合物勘探中高解析度地震剖面上的泥底辟構造真偽的技術方法。Main achievements in this thesis are : one, by thoroughly studying the original ocean - bottom re - positioning software and corresponding algorithm, the author replant the original software from unix workstation to the ms windows environment with vc + + 6. 0 and visual fortran 6. 0 co - programming technique. two, the corresponding algorithm about picking up the first - arrivals and relocating of geophones are studied and realized
對原海底檢波器二次定位軟體進行了全面細致的研究剖析，並對其相關原理進行了較深入的研究，利用visualc ~ （ + + ）與visualfortran語言混合編程技術，將原來基於unix工作站環境的海底檢波器二次定位軟體移植到了微機環境下的mswindows平臺上。The software adopts eofs to describe the sound speed profile in the sea, and takes its bottom depth parameters from inputed digital chart. the software can process more complex 3 - dimension sound field
軟體中採用經驗正交函數來描述海洋中的聲速剖面，海底深度參數以數字海圖的形式輸入，可以處理較復雜的三維情況下的海洋環境聲場。To get the stability of shallow structure foundation and adjacent seabed in cheng dao shallow sea area, we have made an investigation on high resolution echo depth side sonar and shallow strata section etc. and made use of experiment analysis of core, in situ, indoor to compute, analyze and assess the stability on new computing method
為了得到埕島海域淺水區構築物地基及周邊底床穩定性，本文通過高解析度的回聲測深、旁側聲納及淺地層剖面等聲學儀器勘查，並結合鉆孔、現場和室內的實驗分析，採用新的計算方法，對埕島海域淺水區人工構築物地基及周邊底床穩定性進行了計算、分析和評價。Through the settling and analysis of these data, we find that the seabed sediments intensity appears heterogeneity on the plain and the profile under the action of wave loading, i. e., the random or periodic variation of seabed soil intensity in the plain, and hard soil layer in certain depth under the bottom
發現在波浪作用下，黃河口沉積物強度出現了非均勻化，即在平面上，沉積物強度呈現隨機性或間隔性變化；在剖面上，海底面之下一定深度范圍有硬層發育。Sub - bottom seismic profiling system
海底地層剖面儀Since this mehod is applied in the post - stack stage and the recognization of the multiple is subjective, so the application of this method should be made very carefully
本方法不僅對一般海底復反射的摘除有效，對于剖面上其他多餘能量亦能有效地加以去除，但由於摘取之過程是在重合后之剖面進行，且復反射之選取亦較為主觀，所以在應用本方法時必須十分小心謹慎。分享友人
