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。The precision of its calculating results has an direct effect on the design, construction and safe usage. in the typical calculation of the settlement of foundation, additional stress incurring by loading is calculated according to elastic theory which has the same characteristics in semi - indefinated space, the condesion of soil is decided by the condesion experiment of one - demension and the settlement is calculated by adding results of respective layer

面向對象建模支持環境研究及其工具的研製成為當今國際領域的研究熱點，何為優秀的面向對象建模支持環境，目前國際上並沒有統一的標準，各個研究機構對其亦持有不同的觀點，並根據自己的商業需要開發出符合自己特點的建模產品，這些系統仍存在著眾多的弊端，比如幾乎都是基於windows技術，通用性差，擴展性方面受到限制等。國內在這方面的研究仍處于起步階段，已有的建模系統大都基於結構化建模技術或者無法支持最新的面向對象建模技術如uml標準。本文根據作者近幾年的研究結果，結合目前和未來的技術從理論上探討了面向對象建模支持環境，提出了一些建模標準和觀點，並詳細介紹了基於這種研究成果下自行開發的面向對象建模支持系統umlware ，論述涉及該系統的研製技術、開發思路和建模策略。The flow equations are solved using finite difference technique. using body - fitted curvilinear coordinate system treated the boundary conditions. by iteratively solving the flow governing equation and the blade equation, the design of axial flow pump impeller in the quasi - three - dimensional rotational flow can be performed according to the angular momentum distribution, the blade which was designed in the lifting method, flow channel and the blade thickness given

在1898年馬建忠撰寫的第一部漢語語法專著《馬氏文通》問世到現在的一百多年裡，語法教學在中學語文學科中的地位始終沒有確定下來， 「淡化」甚至「取消」語法教學的觀點時而浮現于語文教學的理論與實踐中。問題的癥結何在?筆者通過定量與定性分析，現實調查與理論探討相結合，認為中學語法教學的主要癥結在於：中學語法教學確立的目標脫離廣大師生的教情與學情實際；中學語法內容體系來源於語法研究成果，而語法研究中存在著諸多弊端，從而直接或間接地影響著中學語法教學；人們對中學語法教學目的的認識也有一個不斷趨向科學的過程：語法教材也存在著內容及編排的局限性? ?中學語法教材的依據語法體系本身具有局限性，語文教材中的語法的內容與編排也具有一定的局限性，諸如沒有遵循學生的認識規律，高中沒有語法教學的內容和要求，語法初中沒有過關，高中則更趨回生等；再者，教師素質及教學方法不適應，沒有把靜態的語法教學與動態的語法教學結合起來，忽視了教學語法的實用性的特點；長期以來，中學語法教學的意義定位不準，不是偏高就是偏低等等，由此，筆者得出結論：由於上述問題的存在，導致了「語法無用」進而要求「淡化語法」甚至「取消語法」論調的產生，而並非語法知識本身無用，因此，今後語法教學改革的方向是解決這些問題，而不是淡化和取消。Above all, with the data acquired by tests, this thesis has analysized the lateral resistanc, longitudinal resistance and rail creep etc between ballast and sleeper before and after mass machine work, discussed the effect of mass machine on stability of continuously welded rail track, reseached the change regularity of fastening - down temperature of rail, which is resulted by mass machine work, and have settled the suitable range of work temperature which guarantees the stability of jointless railway. what ' s more, this thesis has put forward the appropriate work pattern, work temperature and work area for mass machine work in future. at the same time, this thesis has given rational suggestions about some conditions worth of attention in production of mass machine, which can in return raise the work productiveness of mass machine. at last, this thesis has considered formulating reasonable measures for operation organization and work standard, so that mass machine work can play an important role in maintenance, which can reduce work load, raise work efficiency and maintenance cost in daily maintenance

它可應用於任何復雜的傳播環境中，能找到發射機到接收機之間的所有電波傳播路徑而無須冗餘的計算，是一種準三維的預測模型；另外，從本質上講，它仍然是一種基於鏡像理論的點對點的射線跟蹤法，所以它無須進行接收測試；而且由於採用了反向演算法，運用數據結構中多叉樹的概念，先確定需要計算的場點位置，找出所有能從源點到達場點的射線，並且可一次性建立一個虛擬源樹，以後每次的計算只要通過對該樹進行後序遍歷即可，大大提高了運算速度，因而有較高的接收效率與精度。本文對該模型進行了相應的模擬，並將其預測結果與實測結果以及基於cost231經驗性模型和基於強力射線跟蹤確定性模型的預測結果進行了比較，結果表明了該模型的優越性。However, traditional mosfet models in hspice library are built for lateral mosfet with small power and they can ’ t represent the characteristics of power vdmos well
