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。 -
Due to the short distance among the planes which fly in a group, the conventional low resolution radar can not distinguish them in both distance and azimuth ? if we use the technology of isar to resolve the difference among doppler frequency of the targets and obtain a fine resolution cross - cross image, we may separate them, but a long time of coherent processing is needed <, for the formation targets, it can be approximately divided to rigid body and nonrigid body, so for the formation targets, that can be regarded as rigid which has a relative position and an identical movement, can be approximately considered as a large target, and be compensated by translational phase with the rule of minimum entropy, but for the most those cannot accord with the approximation of rigid, being the doppler - frequency of the aim is linear changed, by the relax method with short data, increases the resolving performance of multiple target to the aim in the frequency domain, since cross - range resolution is based on the accumulative time, so it is greatly improve the resolution to formation targets by the instant cross - range image which produced by radon - wigner transformation
低分辨isan成像及干涉技術應用研究一因此直接無法分辨編隊目標的架數，我們借鑒isar的技術，通過較長時間的相干積累，在多普勒頻域上對目標進行分辨。而對于編隊目標，可分為近似剛性的多目標和非剛性的多目標，所以對于可以近似為剛體的編隊目標相對位置固定，運動方式一致，可以近似看作一個大目標，採用最小墑準則對平動相位的進行補償，但是大多數並不滿足剛體近似的編隊目標，由於目標在相干積累時間的多普勒頻率近似呈線性變化，通過對較短數據利用relax的時頻分析方法，提高了頻率域上目標分辨的性能。由於橫向解析度取塊于橫向積累時間，所以利用radnwigner變換得到瞬時的一維橫向距離像大大提高了對編隊目標的分辨，對模擬和實測數據的大量分析結果表明此方法的有效性和可行。 -
Such planes could fly to their destinations with the speed of their short wings, then extend their inflatables to burn less fuel while they loitered or slowed down for landing
這麼一來，這類飛機可用較短的機翼提高速度飛到目的地，並在盤旋或減速準備降落時，拉長充氣式機翼，以減少燃料消耗。 -
Baking - free brick was made by using fly ash, sand, cement and other industrial wastes, which makes the cost of material low. furthermore, when it was made, the degree of mechanization is very high, using few workers, production cycle is short, thus the cost was lowered
免燒磚是採用粉煤灰、砂子、石粉、礦渣等工業廢渣按一定比例加入水泥振動，強力壓制而成，原料來源價格低，加之生產時機械化程度高，用人少，生產周期短，因此成本低，免燒磚的價格比紅磚低，裝卸時不容易損壞邊角，且沒有粉塵，衛生條件好，對人體的呼吸道傷害小。 -
Based on the studies, it is proved that lime fly - ash mixture is provided with more time to compact during construction compared with other base materials in forming even higher structure strength but not in reducing strength within 1 ~ 3 days period of time. meanwhile, structure strength of the mixture which has been destroyed by some reasons can be recovered in a great extent if original structure is regained. on the other hand, during the high temperature summer season or under other conditions promoting the mixture to form strength, continuous construction process between lime fly - ash base course and bituminous pavement can be carried out to complete the building process in short time
確認二灰基層材料與其它類型的基層材料相比，在施工時具有較長的施工碾壓成型時間，在一定時間里延遲成型的二灰基層強度不僅不降低，反而還有一定程度的提高；與此同時早期受到破壞的二灰材料在恢復整體性的條件下，結構強度能夠在很大程度上得到再恢復；另一方面，在夏季高溫季節以及在強化基層強度形成的前提下，二灰類基層和瀝青面層可以採用連續施工的方式在較短的時間里完成路面鋪築工作。
