Data used in this work are north pacific ssta, 160 stations precipitation of china, and ncep reanalysis data. main results are as follow : ( 1 ) it is found that a apparent transition of north pacific ssta in later 1970 ' s : eastern and middle - equatorial pacific ssta turns from cold to warm with area extending, and mid - latitude pacific ( west wind drift zone ) turns from warm to cold. during this transition of ssta, different characters also appear in el nino and la nina : before 1976, la nina happens more frequently, and its duration is longer, el nino zone develops from negative ssta in the early stage ; after 1976, el nino happens a little bit frequent and longer with more intensity than before, el nino zone develops from positive ssta in the early stage ; the course of ssta variation has an enso cycle of 2 - 6 years, annual oscillation of 8 - 9 years, and decadal variation of about 22 years
本文採用1950 - 1999年北太平洋海表溫度（ sst ） 、中國160站夏季降水和ncep再分析的歐亞500hpa高度場等資料，利用eof 、 svd 、小波分析、合成分析和相關分析等方法，在分析北太平洋海溫時空分佈特徵的基礎上，著重探討了海溫異常及其年代際變化對我國東部降水的影響，並對降水、高度場和海溫三者之間的關系進行了分析，以試圖尋找三者異常之間可能的聯系，主要結論如下： （ 1 ） 1976年前後，北太平洋海溫經歷了一次明顯的轉變，赤道中、東太平洋厄爾尼諾海區由冷轉暖，暖水范圍增大，中緯度西風漂流區海溫由暖轉冷；在這樣的年代際背景下，厄爾尼諾、拉尼娜事件在不同的時期也有不同的特徵：在76年前，拉尼娜事件發生頻率高，持續時間長，事件起始於負海溫距平；而76年後，則是厄爾尼諾事件發生頻率略高，持續時間長，強度增大，事件起始於正海溫距平。 -

Guided by the basic theory of high - resolution sequence stratigraphy, and based on the core observation, the analysis of chemical composition of rocks, and data of natural potential logging and apparent resistivity logging, authors have set up the high - resolution sequence stratigraphy framework of the ore - hosting yaojia formation, and discussed the relation of the stratigraphic structure of the middle cycle, as well as the paleotopography, the micro - facies to the formation of uranium deposit
在高解析度層序地層學基本理論指導下，筆者通過巖心觀察、巖石化學組分分析、自然電位及視電阻率測井等手段，建立了賦鈾巖系姚家組高解析度層序地層格架，探討了中期旋迴內地層結構、古地形和沉積微相與鈾礦床形成的關系。 -
This system is utilized the programmable controller ( plc ) bearing of substitution rule ( the figure is apparent the form, writing instrument, individual loop controller, the hand is holded the utensil and is reached to assist the bearing unit and await ), achieve the 29mw ' s cycle stream of water warmhearted water boiler, oxygen remover, warmhearted net system control system together with monitoring voluntarily of electric section together with control being living, the rule to call off greats quantity displays the bearing in that system, boiler, oxygen remover, the warmhearted net operation is achieved crt and is supervised completely, manipulates personnel staff is living inner place the control cabin completely completees failure - free operation and trouble removal operation. the predictive target of putting ino production queen is the boiler, oxygen remover, the warmhearted net is achieved comprehensive self - regulation, moreover be able to be over a long period of time, steady secure operation
本系統利用可編程式控制制器（ plc ）替代常規的儀表（數顯表、記錄儀、單迴路控制器、手操器及輔助儀表裝置等） ，實現29mw循環流化床熱水鍋爐、除氧器、熱網系統控制系統與電氣部分的自動監測與控制。在該系統中取消大量的常規顯示儀表，鍋爐、除氧器、熱網的運行實現crt全面監控，操作人員在控制室內全部完成正常運行及事故處理操作。投產后的預期目標是鍋爐、除氧器、熱網實現全面自動調節，並能長期、穩定、安全運行。 -
Moreover, seasonal cycle also has apparent decadal - scale variety from 1909 to 2002 : monthly mean temperature in winter time from 1983 to 2002 is obviously warmer than that from 1909 to 1931 ( 3. 7 warmer in february ), while colder in summer ( 0. 2 colder in july and august ) and annual range of temperature is lower 2. 5
季節循環也有明顯的年代際變化： 1909 1931年， 1932 1982年和1983 2002年三個時段，第二時段接近平均狀態，第一和第三時段冬、夏季對比有明顯差異，第三個時段的冬季明顯高於第一時段（ 2月份高3 . 7 ） ，夏季低於第一時段（ 7 、 8月份低0 . 2 ） ，年較差減小了2 . 5 。 -
By synthesis and reanalysis of recent research results on dry and wet deposition of nutrient elements in the southern yellow sea and the east china sea, the results suggest that the concentrations of nutrient elements in aerosol and precipitation show an apparent seasonal cycle with the maximum values in winter and the minimum values in summer, which is close related with the seasonal variations in prevailing winds and precipitation
通過對南黃海及東海海域營養鹽大氣入海通量的研究結果的綜合與再分析，說明黃海及東海海域營養鹽氣溶膠濃度和降水中的離子濃度都有較明顯的季節變化，基本上冬季最大，而夏季最小。這與該區盛行風系和降水量的季節變化有關。
