每天有很多馬來西亞上班族駕車行駛在這些密如蛛網的公路上，但每逢節假日，當人們離開吉隆坡和一些大城市去度假時，高速公路的運輸壓力就顯著增加，各種交通事故的數量以及因此而死亡的人數均會上升。The analysis of the large - scale synoptic situation shows that strong precipitation is closely related to the explosion of monsoon and the intensification of cross - equatorial flow which bring a lot of vapor and meet with cold masses at the eastern of northwest district on 8th, june causing extremely heavy rainfall ; that subtropical high - level jet at 200hpa, subtropical high at 500hpa and low - level jet at 850hpa are the weather backgrounds favorable to strong precipitation ; that the pattern of eastern highs and western lows and the establishment of a low - level jet and the coupling between upper - and low - level patterns that determine that the rain occurred in the east of the northwest china ( on average, this is the rainy season for the south of china, but not for the northwest china ) ; that water vapor comes from southerly and easterly flow which converge at the eastern of northwest district with convergence mainly in lower levels and pbl ; that the high value of the whole - level apparent heat source < q1 > is near the area of large rainfall in the direction of northeasterly - southwesterly agreeable to shear line very well and the condensation latent heat releasing is main heat source with vertical advection item playing key role in q1 and q2 ; that there is a vertical secondary circulation crossing low - lever jet whose ascending branch is at the area of large rainfall ; that the construction of convection instability and conditional symmetry instability results that there is not only deep thermal instability, but also moisture influx and triggering mechanism of thermal instability causing strong torrential rain
作為對比，本文還對2002年6月24 - 25日發生在北京地區的強地形雨進行了分析，並討論陜南、北京地區兩地暴雨的異同點以及地形作用的共性和個性，為兩地暴雨預報提供有益的參考，得出了一些很有意義的結果： 1大尺度環流背景分析表明： （ 1 ） 「 02 . 6 」強降水與6月上旬越赤道氣流和季風爆發密切相關，攜帶大量水汽的偏南氣流與冷空氣於6月8日交匯在西北地區東部，導致了這次強降水的發生； （ 2 ） 200hpa的副熱帶西風急流、 500hpa副高以及850hpa的低空急流的配置非常有利於本文分析之陜西強降水的發展與維持。大尺度形勢分析表明，東高西低形勢場、低空急流的建立和高低空形勢的配置決定了這場降雨出現在西北地區東部。與暴雨區相聯系，存在一支橫越低空急流的經向垂直環流，暴雨區處于該垂直環流的上升支； （ 3 ）偏南和偏東氣流水汽通道在西北地區東部交匯，水汽的輻合積聚主要在對流層低層和行星邊界層內完成； （ 4 ）整層的視熱源< q _ 1 >高值區在暴雨區附近呈東北-西南向分佈，與切變線走向非常一致，降水產生的凝結潛熱釋放是強降水區大氣的主要熱源。On the other hand, the status quo of air transportation keeps increasing, altogether with the quick pace of the economy ' s going up. the density of airplanes in the sky is increasing, meanwhile, the distance between them are much smaller. therefore, it is pivotal to guarantee security of these airplanes
加上我國幅員遼闊，改革開放以來，隨著經濟的持續快速增長，航空運輸業的發展導致了空中交通流量的日益增大，使得空域中飛機密度增加，間距縮小，因而空中交通安全問題十分突出。With expeditiously development of national economy, construction of road traffic are becoming more important. due to the increase of tunnel " s length and quantity, and the increase of density of road traffic, fatalness of fire in a roadway tunnel are raising gradually
由於隧道數量和隧道長度以及公路交通密度的日益增長，以及隧道內火災特性的特殊性，公路交通隧道內火災的危險性呈上升趨勢，因此，特長公路隧道內火災的安全性顯得至關重要。With expeditiously development of national economy, construction of road traffic with security and comfortable circumstances are becoming more important. due to the increase of tunnel ' s length and quantity, and the increase of density of road traffic, fatalness of fh - e in a roadway tunnel are rising gradually
隨著隧道數量和隧道長度以及公路交通密度的日益增長，公路隧道內火災事故發生率以及危害的不斷擴大，為隧道提供安全、可靠、舒適的運營環境越來越受到各國專業人士的重視。分享友人
