near-vertical well 中文意思是什麼
near-vertical well
解釋
接近垂直的井-
It was well known that the main process of precipitation formation was collecting cloud water in the warm area and ice phase particles melting in the cold area. positive vertical velocity existed between 700hpa and 500hpa in the warm area and near surface in the cold area. wind convergence existed at the height of 700hpa, and divergence existed above and below the height of 700hpa
通過對降水雲系的綜合研究，建立了河南省春季層狀雲降水概念模型：暖區降水主要通過雲水碰並形成，冷區降水機制以冰粒子融化等冷雲過程為主;暖區700一50ohpa通常有上升氣流，冷區上升氣流分佈在近地面附近: 700沖a存在風場的輻合，其上下則主要是輻散區;水汽主要集中在7o0hpa高度上，暖區水汽來自南、東南方向，冷區水汽以西南輸送為主;暖區位勢不穩定分佈在o 。 -
It ' s proved by the simulation result that, the fuzzy logic model reference adaptive controller adapts the change to the grand crutch force well, which is brought from the vehicle pitch and vertical vibration during the brake process, and the change to the slippage ratio which is near to the perfectness
模擬結果證明，模糊模型參考自適應控制器對于在制動過程中由於車輛前傾和垂向振動引起的地面支承力的變化有較好的自適應能力，制動過程中輪胎縱向滑移率的變化更趨近於理想變化。 -
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。
