level landing
解釋
水平著陸-
Because the well reservation of the advantages of traditional large sacle advertising airboat, thoughtful design and argumentation on every level has been made, the dimension of the airboat reduced to 9 - 16 meters, adaptable area remarkably increased, flying agility obviously improved, a place as large as a playground is enough for it s taking off or landing, a space as size as a bus warehouse is sufficient to store the airboat, the advertising area of the airboat on it s two sides become less to 9 - 12 square meters, the altitude where such airboat can fly is much lower than that that drives person, presenting a little difference in views of the people on the ground, so capable to take the place of human - driving airboat, on the other hand when the size reduced, the operation, use, freight and maintenance become very easy, easy operation become it s first advantage : remote controllable, no professional driver needed, common personal can operate it after a short trainning, trainning time ranges from 3 - 5 days single, 15 - 30 days for people
是因為它完美的保留和發展了大型載人廣告飛艇的優勢，為此我們進行了方方面面且深入細致的設計和論證，首先縮小了飛艇的尺寸， 9至16米長，大大的增加了飛艇的適用范圍，使飛行的靈活性得到了改善，學校操場大小的地方就可從容的起飛降落，大客車或大貨車的車庫便能存放，廣告面積雖然也小了，每單側9至12平米，可遙控飛艇的飛行高度也比載人艇的飛行高度低很多，以地面的視覺效果來看效果相差非常小，足以代替載人艇，其次是飛艇縮小后，整艇的操作使用運輸維護也都大大的簡化了，操作簡便是它的第一大優點：由於是遙控飛艇，就不需要專業的駕駛員來操作，普通人經過短期的技術培訓就可勝任，培訓期每單人為三至五天，多人視人數十五至三十天。 -

A large planar microphone array, which consists of 111 microphones, was successfully applied to obtain a two - dimensional mapping of the sound sources on a landing aircraft. the focus of study in this paper is on the landing gear noise source. the spectra, directivities and sound pressure levels of flap side - edge noise of 7 narrow - board commercial aircraft and 7 wide - board commercial aircraft are presented. it is found that the landing gear noise spectrum is broadband with some single tones in some cases. the directivity of the total sound pressure level of a landing gear noise resembles that of a horizontal dipole. the level differences between the various aircraft landing gears are larger than those expected from the airspeed differences. it is thus expected that the louder noise emission of the landing gears can be reduced by redesigning
應用由111個傳聲器組成的平面傳聲器陣列對當前流行的民用客機進場著陸過程中的機體噪聲源進行了實驗測量，本文對七架窄體客機和七架寬體客機的起落架噪聲進行了分析，得到了起落架噪聲的頻譜特性、指向特性和聲級變化.研究發現，起落架噪聲的頻譜是由寬頻隨機噪聲與一些較為明顯的單音噪聲源組成，起落架噪聲的指向性類似於一個水平放置的偶極子.不同飛機起落架噪聲的聲級相差較大，這說明可以通過重新結構設計降低起落架噪聲。 -

China is one of the countries which are harmed by storm surge both tropical and temperate cyclones, the disaster of storm surge can occure every seasons and from south to north in china ' s coastal area. based on the analysis of the features of temporal and spatial changes of storm surge disaster in the recent 50 years, this paper focuses on the frequency changes of historical records in recent 500 years and measured data in recent 50 years of storm surge disaster and the relationships between storm frequency change and climate fluctuation. meanwhlie, the effects of future increase in the frequency of tropical cyclones landing or affecting china and relative sea level rise with global warming on storm surge disaster of china ' s coastal area also discussed. the results show that, in recent 500 years, there are direct relationships between storm frequency change and climate fluctuation, i. e., high global mean temperature correspond with high storm frequency and low mean temperature correspond with low storm frequency. storm surge disaster in china ' s coastal area will be exacerbated with global warming
中國是全球少數幾個同時受臺風風暴潮和溫帶風暴潮危害的國家之一，風暴潮災一年四季，從南到北均可發生.本文基於中國沿海近50年風暴潮災時間變化和空間分佈特點的分析，著重探討了近500年全國及長江、黃河、珠江三角洲的歷史記錄和近50年實測風暴潮災發生頻次的變化及其與氣候波動的關系，並對未來全球變化背景下，中國沿海風暴潮災的變化趨向進行了討論.結果表明:近500年來，中國沿海的風暴潮災在氣溫較高的偏暖時段比氣溫較低的偏冷時段明顯增多.近50年實測臺風暴潮災的變化也是如此，而溫帶風暴湖的變化則與此相反.未來全球變化引起的登陸影響中國的熱帶氣旋頻次增加和相對海平面的上升，均將導致風暴潮災呈加重的趨向 -
