  1. Using monthly mean rainfall and temperature data in north - west of china ( nwc ), the characteristics of rainfall anomaly at rainy season in nwc and the inter - annual varieties of drought / flood are diagnosed by means of eof, reof and wavelet analysis et al. and the ncep / ncar monthly reanalyzed data are employed to analyse the evolution character of water vapor flux and it ' s divergence flux, 500hpa height and u, v wind field. results show that ( a ) the space distribution of rainfall anomaly can be separated into seven climate sensitive areas, the first and the third region have the same rought / flood trend

    本文使用西北（區） 168個站1961 2000年6 9月（主汛期）月平均降水、溫度資料，運用eof 、 reof 、小波分析等方法診斷了主汛期月降水異常和旱澇的年代際變化；同時利用ncep ncar月平均資料，分析了強（弱）季風年西北空中水汽通量及其散度場、 500hpa高度場、 u 、 v風場的演變特徵，結果表明： （ a ）西北汛期降水可分為七個氣候異常區，第一、三異常區旱澇趨勢相同。
  2. ( d ) in the weak monsoon year, nwc lies in the northwest airflow region, west and south wind, as well as moisture transportation are remarkably reduced. except part of the first field, there is vapour flux divergenceon in nwc ( e ) in the strong monsoon years, the height field is low on the west and high on the east, west and south wind, and it ' s vapor flux transportation, are evidently boosted up. there is vapour flux conflurnce in the he first and sixth region

    （ d ）弱夏季風年，西北區高度場西高東低，處于脊前西北氣流的控制之下，西風和南風明顯減小，水汽通量輸送也大大減少，除一區的甘肅河東大部（ 30 35 n ， 101 105 e ）存在水汽通量輻合外，其它地區為水汽通量輻散（弱的輻合） 。 （ e ）強夏季風年，西北區高度場東高西低，西風和南風明顯增強，水汽通量輸送同樣顯著增強，一、三區存在大范圍的水汽通量輻合。
  3. That is to say, the so - called drought trend in the east of nwc, is not only point to the evolution of precipitation on the ground in the long term, but also to the vapor content in the whole troposphere

    這是上世紀九十年代中後期天水重大幹旱事件發生的一個背景條件。這說明，所謂西北地區東部乾旱化的趨勢，不僅表現在地面降水量的長期演變方面，而且表現在對流層整層水汽含量方面。
  4. It is not practical to supply full wavelength converter in a network because of some problem such as long price and complex techniques. so no wavelength converter ( nwc ) and spare wavelength converter ( swc ) are considered in our following chapter. chapter 3 : prototype of ilp model of static rwa issue is proposed here

    由於光跡是較新的一種設計方案，現有的光跡模型只是最基本最簡單的模型，還是很粗糙的，並且還沒有涉及波長一致性約束，因此，本章在改進了光跡模型描述的基礎上，增加了考慮到波長一致性條件時光跡及其保護模型的描述，建模和模擬。
  5. Secondly, the mean seasonal climate characteristics of atmosphere water vapor and its transport flux over nwc respectively in january, april, july and october during the past 50 years was discussed

    其次分析了50年來1 、 4 、 7 、 10各月份西北地區大氣水分和水汽平均輸送的季節性氣候特徵。
  6. ( 4 ) the intensity of the vertical movement of the air over the east of nwc, from the 1990s ", it tended to weaker, which is regarded as a dynamic background condition

    （ 4 ）西北地區東部垂直運動的強弱具有一定的年代際變化， 90年代以來，強度趨于減弱，成為該區90年代降水減少的一個動力背景。
  7. ( 3 ) the mean features of vapor water in the atmosphere in the east of nwc between during the great drought affair and dry years are contrasted and shows that, the precipitable water in the whole troposphere is evidently reduced, and the vapor transport is also weakened, the degree of convergence of water vapor is lessened

    （ 3 ）對比西北地區東部重大幹旱事件期間和典型濕年大氣水分平均特徵發現：干年西北地區東部全區整層大氣可降水量明顯少於濕年，且水汽輸送減弱，水汽輻合程度也有所減小。
  8. Lastly, the precipitable water ( pv ) and vapor transport flux during the great drought affair in the east of nwc in 1990s " have been analyzed and compared with what during wet years. the reason that resulted to that drought affair was studied from the point of water vapor in the atmosphere

    再次，對上世紀90年代西北地區重大幹旱事件期間大氣可降水量、水汽輸送等進行了分析，並與典型濕年進行對比，從大氣水分特徵的角度探討了這次重大幹旱事件的可能形成原因。
