主要分析了這次過程中的多種物理量，包括渦度、散度、垂直速度、鋒生函數、視熱源、視水汽匯等，對這一暴雨過程有了比較系統的認識。結果表明：在江淮流域存在著有利於發生暴雨的物理量場配置，渦度、散度、垂直速度等物理量，與暴雨的落區都很吻合的；低空急流的產生不僅有利於水汽的輸送，而且高低空急流的耦合造成了有利於強上升運動的配置；鋒生強度隨著降水系統的發展變化，並影響降水強度。We can use the mm5 model in definite time, definite area weather forecasting. we conclude that : : the moving route of this necw in its developing progress was direct - south along latitude, the cold air is rough, and just this made the rough vertical velocity ; the necw southern moving and conflicting with the west pacification sub - tropical high makes rough jet steam. the plenty south - west warm and wet air made by the jet stream gave the rainstorm demanded vapor ;. the rough vertical velocity by jet stream is a main reason in this rainstorm ; the mm5 model uses four - direction analysis data as its input, this avoids some errors occurred in observe and transfer, thus made the result more useful
綜合分析認為： （ 1 ） 、這次冷渦在其發生發展過程中，其移動路徑是沿經圈直線南壓，攜帶的冷空氣勢力較強，形成槽后較強的垂直運動； （ 2 ） 、西太平洋副熱帶高壓偏北位置與東北冷渦南壓形成的急流軸，把源源不斷的西南暖濕氣流輸送到遼西地區，也就是急流軸的左前方位置，為這次暴雨的產生提供了充足的水汽來源； （ 3 ） 、低空急流不但為暴雨輸送水汽，其造成的較強的垂直環流也是產生強降水的一個主要原因； （ 4 ） 、 mm5模式以四維同化資料作為初始場，最大限度地避免了觀測誤差可能造成的積分不穩定，提高了模擬結果的參考價值。Strongly strengthening of the low level jet and releasing of the latent heat of condensation have effect on the occurrance of the disturbance of the moist potential vorticity in low lever, which is important conditions to the genesis and development of mesoscale vortex
低空急流的加強以及凝結潛熱的釋放均可以影響到低層濕位渦擾動的產生，從而有利於中尺度低渦的生成和發展。減弱低空急流的對比實驗證明了低空急流在對流層中低層中尺度低渦的生成和發展過程中起著關鍵性作用。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。The above analysis showed that this heavy rainfall event took on obvious meso - scale characters and was the combination of the three flows, so we can deduce : ( 1 ) surface southeasterly wind and topography may play the main role in this event ; ( 2 ) the easterly cold air rushing into the southern shaanxi province in the lower troposphere was strongly relative to the form of surface cold - front type of occlusion ; ( 3 ) there were two reasons for the secondary circulation ' s strengthen in the evening, one was the effect of a mountain - valley wind and the other may be latent heat leading to ascending motion ; ( 4 ) the shape of potential instability stratification corresponded well with the development of the warm - moisture advection ; and ( 5 ) the vapor providing essential thermodynamics was transported by a southwesterly low - level jet from the bay of bengal and the south china sea. furthermore, with the effect of terrain, the southern shaanxi province became the center of this extremely heavy rain process
中尺度結構分析表明，本次暴雨具有明顯的中尺度特徵，是由三支氣流共同作用的結果，分析發現（ 1 ）地面東南風和地形在這次大暴雨過程起主要作用； （ 2 ）東路冷空氣主要是通過中低層侵入陜南地區的，並與地面冷式錮囚鋒的形成密不可分； （ 3 ）夜博士論文:中尺度地形對陜南暴雨的影響研究間垂直次級環流發展加強可能有兩個原因，一個是由於地形山谷風的作用，另一個是降水的潛熱釋放激發了上升運動: （ 4 ）位勢不穩定層結的形成與低層暖濕平流的發展有很好的對應關系; （ 5 ）本次暴雨的水汽主要靠偏南風急流將孟加拉灣和中國南海的水汽輸送至西北地區東部，為暴雨的發生提供了必要熱力條件。The southeast low - air jet accompanying the tropical cyclone transported plenty of heat and moisture for the storm, the low - level heating and wetting weakeed the stability of the air, and the weak cool air intruded from the low - level and stimulated the convection, thus leading to the heavy storm
伴隨登陸熱帶氣旋生成的低空東南急流為暴雨輸送了豐富的熱量和水汽，低層增暖增濕促使層結不穩定加劇，而西風帶弱冷空氣的侵入對暖濕空氣具有抬升作用，可觸發對流發展和不穩定能量釋放，導致大暴雨產生。Various kinds of carbon steel, alloy steel, stainless steel, 90 and 180seamless elbow, sharp bend elbow, plate tube, concentrated pipe and all kinds of pipe fitting made by of company with intermediate frequency induction heating bending shaping craft are features in smooth surface both in inside and outside, even thickness of pipe wall and other advantages, and our products are proved by state science technology commission, national ministry of labor and other authoritative department after the quality inspection that the products of us conforms to the national standard and different standards of different industries

而它的設計開發方法不同於一般的機械產品，它除了完全按照訂單生產，要求供貨期短及設計工作量大以外，還涉及到熱工、機械、流體力學、結構力學、耐火材料及環境保護等多門學科，傳統的設計方法無法適應激烈的市場競爭，因此迅速改變舊模式，提高設計製造及管理水平，成為企業當務之急。Increasing scale of integration and consumption of power has led to the significant increase in power densities encountered in modern electronic equipment. if we do not pay attention to the thermal management of electronic equipment, the large amount of heat generated by the electronic device would not be under the control. especially in some atrocious surroundings, some devices " working temperature would exceed the rated temperature limit and lead to deteriorate the system stabilization or even make the hole system disabled
現代電子設備的集成度不斷提高、功耗不斷加大，使得熱流密度急劇上升，如果我們在設計階段不注重電子設備的散熱設計，那麼元件所產生的熱流將得不到有效控制，特別是在工作環境比較惡劣或電子設備比較復雜的情況下某些元件的工作溫度就有可能上升到導致整個電子系統的工作不穩定乃至失效。Technical personnel are eager to find the new wall materials, which can not only take place of the solid clay brick but also satisfy the requirement for the energy efficiency in buildings. under the background of the wall material innovation and the energy efficiency in buildings, this paper advances a new idea that the haojiao materials with lights weight and functions of heat preservation and insulation are filled into the cavities of common hollow betonblocks, and a new kind of composite bearing and heat preserving block ( composite block ) comes into being
