The asteroids are the most important small bodies in the solarsystem, and they mainly lies in the two locations - a main belt between the mars ' s orbit and the jupiter ' s and the near - earth space. the most feature of the orbits of near - earth asteroids ( neas ) is that the semi - major axes of the orbits are nearly equal to that of the earth or the perihelia distances are approximate to or even less than the mean distance between the sun and the earth, thus they could move into inside of the earth ' s orbit, so that they might close approach or even colliside with the earth ( or other planets, such as the venus, the mars, etc. ). the characteristic brings about some difficulties in the numerical research during their orbital evolution, which leads to the failure of the normalization technique in the general removal impact singularities of celestial mechanics methods and the symplectic algorithm which is successfully applied to the investigation in quality. by comparing the computation effects of several common numerical methods ( including symplectic algorithm ), and considering the nature of the movement of the small bodies, the corresponding treatments are provided here to improve the reliability of the computation
小行星是太陽系最重要的一類小天體，主要分佈在兩個區域；火星和木星軌道之間的一條主帶和近地空間.近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深入到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞.這一特徵給其軌道演化數值研究帶來一些困難，包括天體力學方法中一般消除碰撞奇點的正規化處理以及對定性研究十分成功的辛演算法都將在不同程度上失效.通過對幾種常用數值方法（包括辛演算法）計算效果的比較，根據小天體運動自身的特性，給出了相應處理措施，從而可提高計算結果的可靠性But in flood years, the convergences in mid - and low - level of troposphere are strong. divergence departure in 200hpa is positive, so the pumping cause the updraft stronger. as we all know, the updraft is better to the rain

通過調查、研究、對比、分析，將元謀縣域經濟發展的現狀定位在：元謀縣是邊疆少數民族地區典型的農業縣，具有農業主導縣所具有的典型特徵，同時也具有山區縣經濟類型的基本特徵；與全國縣域經濟的平均水平相比差距較大，為25左右；與雲南省的平均水平相比僅為50左右；元謀縣由於具有一定的自然優勢，其熱區作物、綠色產業已經非常突出地成為了該縣的主導產業，加之政府能動力發揮得較好，其「龍型經濟」正在逐步形成，發展勢頭看好，縣域經濟的規劃、發展思路清晰明了；工業仍然是元謀縣經濟發展最為薄弱的一環， 「無工不富」是時時懸在縣委、縣政府頭上的一個警鐘。產業結構的調整，二、三產業的大力發展是元謀縣無法繞開而又必須面對的非常艱巨的任務。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。The characteristics of precipitation anomalies in summer, previous and simultaneous ssta and preceding winter accumulated snow depth anomalies corresponding to positive and negative phases of 10 - yr mode and 25 - 30 - yr mode are discussed respectively. no matter for 10 - yr mode or for 25 - 30 - yr mode, reverse characteristics corresponding to positive phases and negative phases appear in the above fields. it proves that the decadal variation of sah have a good relation to the decadal variation of other key element of climate system and we can regard sah as a strong signal of the anomalies in the climate system
（ 4 ）夏季南亞高壓東西振蕩具有明顯的年代際變化特徵，本文分別討論了對應於10年周期態的正位相年和負位相年及25 - 30年周期態的正位相年和負位相年時夏季我國降水距平、前期及同期海溫距平及前冬青藏高原積雪距平的分佈特徵，發現無論是10年周期態還是25 - 30年周期態，對于夏季南亞高壓東西振蕩的正位相年和負位相年以上各要素場呈現為很好的反位相特徵，說明夏季南亞高壓的年代際變化與氣候系統中其他要素的年代際變化具有很好的關聯性，可將南亞高壓看作氣候系統中大氣子系統異常的強信號，通過分析南亞高壓的年代際異常可以更直接地研究和預測區域氣候異常。( 4 ) in summer, tropic west pacific ssta decadal change infect precipitation decadal change in south and north of changjiang river maybe by : positive ssta in tropic west pacific weaken the summer monsoon circulation, lead more precipitation in south of changjiang river and less precipitation in north of it, vice versa ; middle north pacific ssta decadal change infect precipitation decadal change in mid - down valley of changjiang river maybe by : when ssta is negative in middle north pacific, the height field in tropic rises obviously, the subtropical high strengthens and extends westward, the northern limit retreats southward, leads upper trough retreats northward and move eastward, meiyu front moves northward, then leads more precipitation in mid - down valley of changjiang river, vice versa ; middle northwest pacific - low latitude mid - east pacific infects precipitation in north china possibly by change the activity of northeast china cyclone
（ 4 ）熱帶西太平洋ssta年代際變化影響夏季中國長江南北降水年代際變化的可能機制是熱帶西太平洋海表溫度正（負）異常減弱（加強）東亞夏季風環流，從而使江南降水增加（減少） ，江北降水減少（增加） ；夏季中部北太平洋ssta年代際變化影響中國長江中下游地區夏季降水年代際變化的可能機制是中部北太平洋海表溫度負異常，將導致熱帶地區高度場普遍增高，副高加強西伸，副高北界南退，致使高空槽北縮東移，梅雨鋒西移北進，中國長江游中游、中卜游降水增多，反之亦反；夏季中高緯西北太平洋一低緯中東太平洋反向距平分佈結構影響中國東北降水的可能機制是低緯中東太平洋海表溫為負異常。The development of the western region is to contain and narrow the development gap among all regions gradually and realize coordinating development of regional economy and purpose of social equality
