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。According to the special shape and operate requirements of the torpedo, the structure and moulding process of the torpedo shell are established, in which the body and overlay block with grooves are moulded by fiber winding, and close moulding respectively with the adhesive by limited stop compression. in the light of the selection of raw material system, composite system with outstanding performance are defined, based on which the mechanical properties are tested., with the overall consideration of structural characters and design demands, the main factors which may have effects on the strength and stability ( including stiffness section dimension, stiffeners space, skin thickness and skin lay angle ) is optimized one by one for the structure design parameters on the base of the fem model of skin, stiffness and layover block by fem. as a result, the prototype with 1 : 1 proportion and its structure and lay optimization design are completed. the moulding technology for polyurethane foam moulding the stiffened shell is obtai ned in terms of the design, manufacture moulding, experimental mould and tooling
依據在研產品特殊的外型結構和使用要求，確定了該型號水雷復合材料殼體的具體結構形式和復合成型工藝路線，即由纖維纏繞工藝成型主體異形件，閉模成型帶通槽外貼塊，用限位加壓工裝實現粘接的工藝路線；通過對原材料體系的篩選，確定了綜合性能較好的復合材料體系，以此為基礎進行了力學性能測試；運用有限元方法，建立了蒙皮、筋條和外貼塊的分析模型，綜合考慮結構特點和設計要求，對影響結構強度與穩定性的主要因素（包括筋截面尺寸、筋間距、蒙皮厚度、蒙皮鋪層角度）分別進行了結構設計參數的優選，最終完成了復合材料異形耐外壓殼體1 : 1樣件和縮比實驗件結構及鋪層優化設計；完成了聚氨酯泡沫胎成型內置加筋殼體的成型工藝技術研究；對縮比件進行外壓性能測試，並給出了應力、應變測試結果。This paper discusses the mathematical methods involved in the displacement of the buildings of type 2, 3 and 4 for maintaining the right interrelationships between the street and the nearby building symbols when the ground size of corresponding street symbols are broadened for compilation of maps in smaller scales, and experimental results are given
摘要介紹了在地圖縮編中因道路符號所對應的實際尺寸加寬而破壞了建築物與道路符號的正確關系時，針對第二、三、四類建築物進行移位所涉及的數學方法，並給出了實驗結果。A vlsi very large scale integration architecture is also proposed to implement the improved motion estimation algorithm. experimental results show that this algorithm - hardware co - design gives better tradeoff of gate - count and throughput than the existing ones and is a proper solution for the variable block size motion estimation in avs
考慮到avs主要面向圖像尺寸較大的高清數字電視壓縮，這種高復雜度的運算已經超過了現有通用處理器的運算能力，因此有必要設計專門的快速演算法和與這種演算法相匹配的硬體加速器。Wavelet transform becomes a superior timefrequency localization method due to its mathematical property itself it has muiti - resolution characteristics. by flexing and moving a base wavelet, which must satisfy some condition, we can analyze signals in multi - scale finely, so it is called " math microscope "
它具有多分辨分析的特點，通過某個滿足一定要求的基小波的伸縮和平移等運算功能對信號進行多尺度細化分析，因而能聚焦到信號分析的任何細節，被譽為「數學顯微鏡」 。Wavelet transform is a time and frequency local transformation and it can withdraw the information from the signal. through the calculate function making the muti - scale analysis it resolves many difficult problems which fourier transformation ca n ' t resolve. in recent years the researches and the applications of wavelet transform on the image compression are flourish, but because wavelet transform is very complicated and its apply has certain localizations
小波變換是一個時間和頻率的局域變換，因而能有效的從信號中提取信息，通過伸縮和平移等運算功能對函數或信號進行多尺度細化分析，解決了fourier變換不能解決的許多困難問題。近年來小波變換在圖像壓縮的研究和應用都十分活躍，但是由於小波的理論很復雜，因此應用起來就有一定的局限性。China railway department have made out related technical standard and document to analysis and design it though it is touch and hard job to design the cylindrical spiral spring by manual. so it is urgent necessary to develop a special cad software. in this paper, the design thought and flowchart of special railway spring suspension cad software has been deeply described and some resource codes and instances have been inserted
對于鐵路車輛專用螺旋圓彈簧的設計，鐵道部制定了詳細的技術標準和規範文件，但是採用手工設計與驗算顯得十分繁瑣，計算量大，因此開發了鐵路車輛典型零件「圓柱螺旋壓縮彈簧」專用cad軟體，對于合理設計其結構尺寸，選擇適宜的結構參數，提高設計效率和設計質量具有十分重要的現實意義論文敘述了所開發的鐵路車輛典型零件「圓柱螺旋壓縮彈簧」專用cad軟體的主要設計思想和設計流程，並給出一些源代碼和例子。分享友人
