In the range of flight mach number mo = 3 ~ 7, in order to take the advantage of ramjet and scramjet, a fix - shaped dual - mode scramjet, in which both subsonic and supersonic combustion can be obtained, is used for hypersonic vehicle
在飛行馬赫數m _ = 3 - 7的范圍內，為充分發揮沖壓發動機的性能優勢，高超聲速飛行器採用了既能在亞聲速燃燒模態，又能在超聲速燃燒模態下工作的固定幾何形狀的雙模態沖壓發動機。 -
Dual - mode ramjet engine which gathers the advantages of both ramjet and scramjet is a new - style airbreathing propulsion device. it can operate over a wide mach number ranges ( m = 3 - 8 ). it is of remarkable performance and great potential application for hypersonic vehicle
雙模態沖壓發動機是綜合了亞燃沖壓發動機和超燃沖壓發動機優勢的一種新型的吸氣式動力裝置，它可以在比較寬廣的飛行馬赫數范圍內工作（ m 3 8 ） ，具有良好的工作性能和廣闊的應用前景。 -
Based on the characteristics of vehicle structure, the paper presents the check technique for traffic vehicle from the remote sensing images, introduces the transformation process from the grey scale of image to the dual value image, and finally expounds the marginal check ( contour tracing ), image dividing, mode distinguishing and the vision of machine
摘要在分析固定場景中車輛圖片結構特徵的基礎上，提出了從遙感圖中檢測車輛的方法，具體介紹了將遙感灰度圖像轉換為二值圖像，並進一步闡述了邊緣檢測（輪廊的跟蹤） 、圖像分割、模式識別、機器視覺等作用。 -
There are great differences between ground test of a flight vehicle ' s aerodynamics and that of a dual - mode scramjet when ground test facilities are used to do experiments on a dual - mode scramjet engine, the components of incoming flow and its parameters, including total pressure, total temperature ( or total enthalpy ) and velocity must be simulated. at the same time, since the fuel ' s resident time within a combustor is very short, on the order of one millisecond, it is difficult to measure the flow - fields
進行雙模態沖壓發動機地面試驗研究時，必須要求試驗設備能模擬實際飛行條件下來流氣體的組分、總壓、總溫（或總焓）以及來流氣體的流動速度；同時由於燃料在燃燒室內駐留的時間很短，一般為毫秒量級，從而使流場物理量的測定顯得非常困難。 -
In this thesis, can bus is used as the system bus, concentrating the research on the feasibility of using redundancy can bus technology in large - scale motor vehicle safety performance detecting & control system. this thesis first gives an overall design of the data collection and control system applied to the front end of a large - scale motor vehicle safety performance detecting & control system. regarding that the bus controller, bus driver and bus transfer medium would fail to function easily, the dual mode cold - redundancy structure is adopted in system to ensure the reliability
本文採用can總線作為系統總線，重點研究冗餘can總線技術應用於大型機動車安全性能測控系統的可行性並進行驗證:首先對基於冗餘can總線的機動車安全性能測控系統的前端數據採集與控制系統進行了總體設計，考慮到總線控制器、總線驅動器和總線介質都是容易出故障的部件，系統採用了二模冷冗餘結構來保障can總線通訊的可靠進行;其次，根據系統需要，設計了基於c8051f021的帶冗餘can總線通道的數據採集與控制模塊，用於採集與處理檢測現場的模擬信號和數字信號，並自行開發了can總線應用層協議以及應用軟體，通過冗餘can總線實現與上位機的可靠通訊;然後，為了驗證冗餘can總線設計方案的可行性，搭建試驗平臺並進行can總線故障切換的試驗;最後對課題的研究工作進行了總結與展望。
