From a. d. 878 to a. d. 978, there was a large population immigration at the end of tang dynasty and the five dynasties in wenzhou, its causes were : huang chaos army ' s military activities in the south of the yangtze river caused the migration from the harassed around areas ( especially eastern fujian ) into wenzhou ; that zhu bao controlled and separated wenzhou kept it relatively more stable society for more twenty years than its around areas ; different political situation of qian ' s regime in wu and yue and wang ' s regime in mm and yue caused large - scale migration from fujian to southern zhejiaug ; the good political achievements of qian ' s local officials of stratocracy promoted wenzhou ' s development
摘要溫州唐末五代出現人口大量內遷的100年（ 878 - 978 ） ，其原因是：黃巢義軍在南方的活動導致周邊被擾掠地區（特別是閩東）向溫州移民；朱褒割據的溫州與周邊州縣相比維持了20多年的相對穩定；吳越錢氏與閩越王氏的不同政局構成福建大規模向浙南移民；錢氏軍政地方長官的良好政績更促進了溫州的開發。 -

It s interesting, just before we came on stage here, i was reflecting on the different and varied day i d had, beginning reasonably early this morning, but it included a speech earlier today on migration and the difficulties of coping with large migration flows and that s one of the subjects that confronts countries right round the world in a way that is dramatically different from a few decades ago
就在我站在這個講臺上之前，我還在回想我剛剛度過的多彩的、與眾不同的上午。這一天開始的比較早，早些時候我做了一個有關移民和應對大規模移民潮所遇到的困難的講話。這是當今世界上許多國家共同面臨的問題，而幾十年前的情況與現在是多麼的不同。 -
By this equation, 3 - d migration of seismic data for an irregular acquisition geometry can be done directly
利用該方程可實現對不規則測區直接進行三維偏移。 -
On the basis of former working experience ( reference literature ), and using methods of 3d seismic data interactive interpretation systems including logging constraint seismic inverse technology, an exact geologic model of kinxi area including recent exploration wells, borehole loggings, well loggings, and complete 3d seismic data has been established. there exist two kinds of hydrocarbon pool - forming models, these being the lateral and vertical migration - accumulating models. using as the base of the dynamic systems for pool - forming, all associated reservoir types and d istribution have been studi ed, incl uding accumulation and pool - forming models
筆者在以往工作的基礎上，利用新鉆探井、錄井、測井、地震等資料，運用地震資料人機聯作解釋系統，進行地震資料的測井約束反演等，建立墾西地區的精細模型，並利用成藏動力學系統的理論，研究墾西地區的油藏形成、分佈及運聚模式，提高了對地下油氣藏情況的客觀認識，有效指導該區的勘探開發工作。 -
