Dr hon david li raised a question on combating regional air pollution problem, noting that the poor air quality was caused by a very still wind condition and incoming air pollutants brought in by an air stream from the prd region
李國寶議員提出有關解決區域性空氣污染問題的質詢，當中指出空氣質素惡劣，是因風力非常微弱及氣流將珠江三角洲地區的空氣污染物吹往本港所致。For instance, hot weather and rising air can help dispersion of air pollutants ; rainfall can wash out certain pollutants in the air ; an occasional phenomenon known as temperature inversion can trap air pollutants in the lower atmosphere ; and still wind conditions can inhibit effective dispersion of air pollutants. moreover, when a weak northerly wind prevails in southern china, the impact of regional air pollution on hong kong will become more serious
例如，炎熱天氣和上升的空氣有助空氣污染物消散；降雨可沖走空氣中部份的污染物；偶爾出現的逆溫層現象能把空氣污染物困在大氣的低層；風靜的情況可引致空氣污染物不能有效消散；及當華南地區吹微弱北風時，整個香港受區域性空氣污染問題影響也會特別嚴重。Second, negative dispersion without absorption, which leads to superluminal light propagation, is achievable in the central resonance structure of the dispersion spectrum. the negative dispersion is slightly weakened as the spacings between dressed states increase
其次，在色散光譜的中心區域，呈現出無吸收負色散，這種效應能夠導致超光速傳播，但它隨著修飾態間距增加而減弱。Regional difference in lower - level temperature dv and pressure dv are greatly weakened and dv of llj is distinctly faint without the nanling ridge. this result show that nanling ridge acts as a critical role in the establishment of dv of the lower - level temperature and pressure, which give rise to the dv of llj in south china
而當模式中僅僅去掉南嶺和武夷山山脈地形后，低層大氣溫度場日變化的區域性差異明顯變弱，梅雨低壓帶南側原南嶺山脈所在地的溫度日較差明顯減小，使得梅雨低壓槽與華南地區之間的南北向水平溫度梯度和水平氣壓梯度的日較差顯著變小，導致華南低空急流日變化的顯著減弱。The simulations results show that the spoiler is available to make the fuel and the oxidizer coming from the former to stay in the cavity for a long time, to let the fuel and oxidizer mix and burn completely. since there is a high temperature zone forming by vortex in the middle of the motor, it required a restricted thermal protection. the plate with holes decreased the vortex function in the cavity, which could not promote the combustion efficiency, but to decrease temperature in the cavity and be benefit to thermal protection of the wall
計算結果分析表明:擾流板可以使燃料和氧化劑在擾流腔內的滯留時間加長，促進燃料與氧化劑的摻混燃燒，提高燃燒效率，但由於渦流在發動機的中間部位形成了高溫燃燒區域，致使局部燃料和絕熱層燒蝕速率增大，加大了熱防護的難度;孔板結構減弱了擾流腔內迴流區的漩流作用，不能增加推進劑燃燒效率，但可以使擾流腔內的溫度降低，給壁面熱防護帶來好處。Not only is the production - oriented vat detrimental to the development of foreign trade, the advance of technology, the optimization of industrial structures, the balance of regional economy, the specialization and collaboration of production, the imposition of taxes, the sustaining increase of state revenue etc., but it also disrupts the optimization of the enterprises " organization structures, weakens the function of the tax lever, breaks the tax credit " chain ", increases the difficulty in tax credit based on invoices and leads to discriminatory tax burden among industrial and commercial enterprises
生產型增值稅不利於對外貿易的發展，不利於技術的進步，不利於優化產業結構，不利於平衡區域經濟，不利於專業化、協作化生產，干擾企業組織結構的優化，不利於稅款的徵收，不利於國家財政的持續增長，弱化了稅收杠桿的作用，不利於外資的引進，導致扣稅「鏈條」中斷，增加發票扣稅的難度，導致工商企業間的稅負不平衡。A developed simple m - s model for image segmentation in geometric active contour model is presented based on intra - region similar and inter - region dissimilar properties. the model constructs an energy ( cost ) function, which is made of intra - region variations and weighting squares of subtraction of region mean values. using gradient - descent methods, the energy function is minimized and we get a curve evolution equation that segments image
基於區域內一致性加權區域間差異性構造能量函數，利用最陡梯度法使能量函數最小化，提出了一種改進的簡化mumford - shah （ m - s ）圖像分割模型，該模型利用區域內方差描述區域內一致性，區域間平均灰度值之差的平方描述區域間差異性，實驗結果表明，通過調節加權系數，該模型對弱邊界圖像分割具有較強的適應性。The most of time in this period of time, the relationship between the people in this basin and the nature is opposite, thereby in a certain way it causes the further fragileness in its natural eco - environment and makes the direction of deterioration to be in constant transformation, and it has already seriously intimidated the normal producing live of the people in the basin
該時段的大部分時間，盆地內人與自然的關系基本上是對立的，從而在很大程度上導致了其自然生態環境更加脆弱並向惡化的方向持續變遷，已經嚴重威脅到該區域人類正常的生產生活。The results are as follows : ( 1 ) the first industry distribution is disperse and same with the agriculture resource ' s spatial distribution, the second industry distribution is centralized and same with the mineral resources, the third industry centralize on the large and middle cities and the tourism resources abundant region ; ( 2 ) the eco - environment effect of the industrial spatial structure is obvious in gansu ; ( 3 ) the eco - environment and the industrial spatial structure affect each other, strengthening the eco - environment regional difference and aggravating the frailty of the eco - environment
得出以下結論： （ 1 ）甘肅省第一產業分佈分散且與農業資源的空間分佈態勢基本一致，第二產業發展空間高度集中且與礦產資源分佈一致，第三產業集中在大中城市和旅遊資源豐富的地區； （ 2 ）甘肅省產業空間結構的生態環境效應具有明顯的空間差異； （ 3 ）甘肅省生態環境地域分異與產業空間結構分異交互脅迫，強化了生態環境的地域分異，加劇了生態環境的脆弱性。( 4 ) based on the ncar ccm3 simulations, the influence of the previously winter kuroshio ssta on the easm is investigated. results from the simulations are highly coincidence with the observations, namely, the winter kuroshio ssta may impacts the subsequent year east china summer rainfall by making influencing on the strength and location of the west - northern pacific high and the easm systems
（ 4 ）利用ncarccm3模式模擬冬季黑潮區域海溫異常對東亞夏季風的影響，模式模擬的結果與統計分析結果是一致的，即前期冬季黑潮區域海溫異常可以通過影響次年夏季的西太平洋副熱帶高壓的強度和位置變化以及東亞夏季風環流的強弱，從而進一步影響我國東部地區的降水，尤其是長江中下游地區。When a temperature inversion is formed in the pearl river delta ( prd ) region, or when a weak northerly or northwesterly wind prevails, ambient air pollutants ( including nitrogen oxides ( nox ) and volatile organic compounds ( voc ) ) in the region will be trapped easily in the lower atmosphere and cannot be dispersed effectively. the above factors, if coupled with strong sunlight, will generate ozone under photochemical reaction between nox and voc and lead to the phenomenon of photochemical smog
當珠江三角洲區域一帶出現逆溫層，或者吹微弱北或西北風時，區域內空氣中的污染物（包括氮氧化物及揮發性有機化合物）很容易會被困在大氣的低層，不能有效消散；如再加上強烈的陽光，氮氧化物與揮發性有機化合物便會產生光合化學反應，形成臭氧及引致光合化學煙霧現象。分享友人
