The results show that : l ) there are three anomalous high temperature areas and three anomalous low temperature areas, and the whole area high temperature anomaly took place in the late 1980s, whereas the low temperature anomaly in the 1970 ; 2 ) the spatial mode manifests identical variations in the whole area, and the temporal coefficient curve is of 2 - 3 year period oscillation and an interdecadal abrupt in the late 1970s ; 3 ) the variance of interdecadal component is obviously larger than that of interannual in the most part of nespa ; 4 ) the interdecadal variation of the temperature is mainly linear ascendance in the late 1970s, the large range anomalous high ( low ) temperature occurs when the interdecadal and interannual anomaly are both positive ( negative ) in the year ; 5 ) the temperature anomaly is divided into four patterns : southern, northern, eastern and western patterns, in which the interdecadal variation of the southern and western patterns is relatively importance and the interannual variation of eastern and northern pattern is relatively importance
本文用夏季（ 6 - 8月）中國東北地區91個測站44年氣溫資料，對該區夏季氣溫的氣候平均和異常場進行分析，採用諧波分析將異常變化的年代際、年際尺度分量分離，分別分析兩種尺度上氣溫異常的時空特徵，最後應用reof進行了氣溫異常的區劃，研究局域異常變化的年代際、年際分量的變化特徵。結果發現： 1 ）東北夏季有三個異常高溫高發區和三個異常低溫高發區。全區性異常高溫（低溫）階段出現在上世紀80年代后（ 70年代） 。The activity of cold air and interannual variation of low level jet are important cause of interannual variation of the rainfall in april. interannual variation of subtropic high is the main cause of interannual variation of the rainfall in may over north china. there is significant negative correlation between interdecadal variation of the rainfall in april and that of sst in the areas of equatorial indian ocean and tropic middle - east pacifi
華北4月降水與熱帶中東太平洋、赤道印度洋海溫年代際變化呈明顯的負相關:華北5月降水與熱帶中東太平洋、赤道印度洋海溫年代際變化存在明顯的正相關:熱帶海溫的年代際異常引起的副熱帶高壓的年代際異常可能是影響華北4 、 5月降水異常的重要原因。The analyzing results show that, in four types of household activities in the scope of village, the disorder effect generated by the secondary industry is strongest, which by commerce and service activities is stronger, and which by agricultural activity is strong, and which generated by household reproduction and live activ ity is relatively weak. from 1990 to 2002, the disorder extent of household activities in three villages becomes increasing in turn. in terms of their seasonal change, the household activities of wugou and hutuo village mostly fasten on two traditional busy seasons in agriculture, however xiaonan village is in the other way, that is to say, the intensity of household activities is weak in the traditional busy seasons, which is strong around chinese new year
分析結果顯示，在村域農戶活動類型中，以工業生產活動對環境所產生的無序影響最大，其次為農戶商業等活動、農業生產活動、農戶自生產與生活活動；吳溝村、滹沱村、孝南村1990年、 2002年農戶活動無序度均表現出依次增大的特點；在農戶季節活動變化中，吳溝村、滹沱村農戶活動主要集中於兩個傳統的農忙季節，而孝南村則相反，在傳統的農忙季節里，農戶活動強度反而較小，而在春節前後，農戶活動則較為頻繁；在農戶活動月份差異中，滹沱村最大，吳溝村其次，孝南村最小；在農戶活動年際變化中，孝南村變化最大，其次為吳溝村，滹沱村最小。This they do so, in some cases, perhaps prematurely, by reference to their ability to manage the associated risks to monetary and financial stability on a continuous basis, in keeping with the demands arising from the changing scene, and changing risks, of international finance

在海氣系統異常的方差構成中，北太平洋區域以年代際異常為主，熱帶太平洋區域年際和年代際異常相當；表（淺）層海洋與大氣的年代際變化特徵對同一季節、區域是一致的，且20世紀70年代後期到80年代初均發生由低模態向高模態的轉變；北太平洋區域的7月與此不同，這與該季節近表層海溫層結穩定有關；年際尺度的海、氣異常與enso有關，且以熱帶太平洋區域1月最典型， 7月次之，北太平洋區域1月再次之， 7月無明顯關系。According to the rules and considerations which are based and taken into account in the practical work, this paper proposes a new model for distribution maintenance scheduling which intends to find the most economical maintenance schedule without violating any restrictions and also the paper makes a deep research of ga, sa and ts. by constructing two effective instructive rules which derive from the feature of distribution maintenance schedule and introducing ts into mutation operation of ga in the earlier generations, the proposed method improves the convergence of optimization and shortens the calculation time. the proposed model and method are applied to a practical system, and numerical results verify ' the correctness and validity of them
本文結合實際電力調度計劃工作中檢修計劃的制定原則和所要考慮的各種因素，抽象出適合配電網檢修計劃優化的數學模型：對遺傳演算法、模擬退火演算法以及禁忌搜索演算法等多種演算法進行了研究和分析比較，針對遺傳演算法的不足提出了通過對實際問題的分析抽象出一定規則指導演算法在解空間進行搜索和兩階段變異運算元兩項改進措施，並應用於配電網檢修計劃優化，編制了相應的應用軟體；應用該軟體對我國南方某地區供電局某月的檢修計劃進行優化的結果表明，本文所提出的模型和改進的優化方法是正確和有效的。In this paper, the circulation of 20hpa transits to anticyclone type first ( at april the twenty - fourth averagely ) and then the transition transmit downwards, 54 days later it arrive to 70hpa ( at june the seventeenth averagely ). the interannual variation of transition dates in higher layers of middle stratosphere ( 10hpa 20hpa and 30hpa ) is more remarkable than in lower ones ( 50hpa and 70hpa ). the transition dates of 50hpa and 70hpa have notable interdecadal variation feature : they are sooner before 1978 and later after 1978
多年平均20hpa環流最先轉為反氣旋型（平均在4月24日） ，然後逐漸下傳，至70hpa （平均在6月17日）歷時54天；而中平流層上部（ 10hpa 、 20hpa和30hpa ）轉型日期的年際差異較下部（ 50hpa 、 70hpa ）大； 50 、 70hpa層環流轉型日期具有明顯的年代際變化特徵， 1978年以前轉型日期偏早， 1978年以後偏晚。The frequency of the flood and drought has distinct interannual change, floods emergence more and more from 1980, especially in north, there are more and more droughts in north region and no flood from 1980. in autumn, there are least precipitation in south - west region and most precipitation in south - east region, the precipitation difference between them is exceeding 95 % significance level, the difference between them is most prominent in september
