The rising temperature in the cave, the lamp - light ' s toasting and the convictive air made the humidity of the whole or part of the cave descend, which made the speleothem sightseeing dry, cracked and weathering. the acid air from the outer and the highly dense co2 would cause acid erode action to the speleothem sightseeing with water vapor. the existence of lamp - light offered a good chance for the lightloving plant to grow up, thus a lot of bryophyte covered the speleothem sightseeing
洞穴升溫、燈光的烘烤及空氣的對流致使洞穴濕度或局部濕度降低,使景觀產生乾裂、風化;氣流帶入的洞外酸性氣體及高濃度co _ 2在高濕的條件下,結合水汽對洞穴景觀產生酸侵蝕作用;燈光的存在為燈光植物生長提供了條件,使大量的苔蘚類植物生長于鐘乳類景觀的表面;洞外大氣粉塵的進入,給洞穴帶來了非常嚴重的破壞,粉塵在洞內高濕的環境下大量沉降,附著于鐘乳類景觀的表面,致使受污染面發黑,毫無光澤。The mechanism of the downburst formation was also investigated based on the cloud microphysics of the simulated storm and it was found that this downburst was primarily produced by hail loading, and enhanced by hail melting and rain evaporation. and the loading and the melting of hail played a very important role in producing the downburst. the gale at the surface was caused by the severe downburst
從雲微物理學角度分析了此次局地性大風的形成原因,認為由高空冰雹粒子的拖曳產生的負浮力作用是促發強下沉氣流產生的主要原因,其次是冰雹的融化和雨水蒸發冷卻對下沉氣流起加速作用,冰雹的拖曳和融化作用對下沉氣流具有決定性的作用。The descending air is cool and dense, and spreads out on hitting the ground
下沉的空氣較冷和密度高,在接觸到地面時會向外擴散。In contrast, in an area of high pressure, the air at low levels spreads outward and air descends from aloft
相反,在高壓區內空氣往外擴散,逼使上面的空氣下沉。The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition ; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event ; the subsidence flow at the middle and low tropospheric levels is favorable for the setting - up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region ; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event ; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation
結果表明:在中高層暖性高壓脊及地面變性冷高壓穩定維持的大尺度背景條件下,地表凈輻射引起的近地層冷卻是大霧過程的觸發和加強機制;中低空下沉氣流的存在有助於近地層的弱風條件和穩定層結的建立;低層暖平流的輸入和邊界層的淺層抬升是大霧長時間持續的原因;伴隨冷空氣南下的偏北大風是驅使大霧消散的動力因子。As a result of these two meteorological systems, air from the upper atmosphere subsided over hong kong and the rest of the pearl river delta region, inhibiting the upward movement of air that normally helps to disperse pollutants generated in the region
基於這兩種氣象情況,大氣高層的空氣下沉,令本港及珠江三角洲其餘地區所產生的空氣污染物無法隨空氣上升而擴散。In 1999, the dipole existed in between the okhotsk high and the depression in the north of northeast china, thus the okhotsk high became active and maintained, the subh was located to an area quite further south than usual. the high persisted in the east region of nw china, the cold air flowed to the mid - lower reaches of the yangtze river along the high. in the east region of nw china, air steam under troposphere was strong sinking motion, and formatted the negative vorticity region, the vapour flux divergence was divgence. lt was apparently that the rain could n ' t occur in the eastern portin of nw china. in 2000 year, okhotsk high was very weak or did n ' t exist in, there was high in the east asia - japan, the subh is located to an area further north than usual. in the east region of nw china, the trough maintained, air stream under troposphere was strong ascending motion, the cycolonic circulation was prevailing, the vapour flux divergence was intensive convergences the rain easy happened in the east areas of northwest china
4多梅雨1999年鄂霍茨克海阻塞高壓與我國東北北部低壓形成偶極子,使得阻塞高壓穩定少動,西太副高位置偏南,西北地區東部持續受高壓控制,冷空氣沿此高壓流經長江中下游地區上空;在西北地區東部對流層中下層氣流下沉運動較強,呈反氣旋渦度,水汽通量散度輻散,不利於西北地區東部降水。空梅雨2000年相反,鄂霍茨克海高壓減弱甚至不存在,東亞-日本為高壓,西太副高位置偏西偏北,西北地區東部處于西風槽中,對流層中下層氣流上升運動增強,盛行低壓環流,水汽通量散度強烈輻合,有利於降水生成。As a engineer, i have researched the technology of the deposition of the pyrolytic graphite grid ’ s rough in detail and deeply, in order that xuguang electric ltd. co. achieves the producing from the deposition of the pyrolytic graphite grid ’ s rough to grid. in this research, propane and nitrogen gases has been used in the deposition of the pyrolytic graphite grid ’ s rough at about 1800 and in vacuum

由於高、低空急流耦合,在高空急流中心左側產生的下沉運動和高空急流中心右側、低空急流左側產生的上升運動在鋒面上形成一次級環流,次級環流的下沉支運動為對流層高層干空氣和高位渦的下傳提供了動力條件;進一步研究發現,干侵入沿相當位溫密集帶向南向下伸展,引起對流層低層氣旋性渦度的發展;此外,高層乾冷空氣向下注入,導致地面溫度降低、氣壓升高、風速加大、低層輻合增強、上升速度加大,從而促進了新的對流運動,引起降水增強。Third, the fabrication of hollow fibers with sic films has been done with chemical vapor deposition ( cvd ), and the power - transmitting properties of the above samples have been obtained with an austar 360 ftir spectrometer and kyky - 2800 sem. the kind of fiber has a 950um inner diameter and 3m length, and its transmitting loss is about 0. 7db / m which can be suitable for many applications
