摘要時間序列數據庫中相似子序列的搜索，常用滑動窗口、分形插值逼近等方法將時間序列分割成各子序列，線性擬合各分段子序列，計算查詢序列與各子序列的歐氏距離，滿足距離閾值條件的為相似子序列。In some time - critical situation, continuous ssi is computation bottleneck of some solid modeling system. conventional approach for solving continuous ssi often uses intersection algorithm iteratively without taking the characteristic of the surface into account to simplify computation. the dissertation analyzes the intersect curve structure of continue surface, from the point of intersect curve ' s evolution, it describes the relationship between topology of offset surface intersect curve and topology transmit point ( ttp )
等距曲面和運動曲面在cad cam領域中有著重要的應用，在一些時間敏感場合例如數控加工動態模擬，等距曲面和運動曲面等連續變化曲面求交運算已成為這些系統的計算瓶頸，連續變化曲面求交問題的通常解法是採用曲面求交演算法反復迭代計算交線，沒有考慮連續變化曲面交線之間的相似性進行求交簡化，效率上一直不能有很大的提高。The fiber raman amplifiers ( fras ) are more and more attractive for its particular virtues such as on - line, wide band, and low noise etc, and they are very fit for dense wavelength division multiplexing ( dwdm ) system of next generation charactered by its super large capacity and long transmission distance. fras are unsubstitutable in the fields such as optical fiber communication over the ocean, long haul transmission and exploitation of the entire low - loss band of fiber
光纖拉曼放大器因其特有的在線、寬帶、低噪聲等特點而越來越被人們關注，是一種非常適合下一代超大容量、超長距離dwdm系統的光放大器，尤其是在海底跨樣光纖通信、超長距離光纖通信以及開發整個光纖低損耗窗口等方面有著不可替代的優勢。Because of radio wave propagating along the ducts with enhanced fields on the order of the free - space field, the problems of the co - channel interference are more complicate for communication systems with the results of intersystem interference and the formation of other system, and therefore affecting the determination of the coordination distances or the optimization of the distribution and separation of delay, and for surveillance system such as radar system the problems can be radar holes or the extensions of detect range
對于通信電路，它使系統間的相互干擾問題變得復雜，既可能幹擾其他系統又可能形成另外的系統，從而影響系統的有關參數如中繼電路的最佳組合（分佈、間隔）和協調距離，對于探測系統產生的則是雷達空洞、超視距探測等問題。這些問題對相關無線電系統特別是軍事應用系統可能是致命的，因而以波導傳播為代表的反常傳播特性研究受到極大重視。Pythagorean hodographs exhibit remarkably attractive properties for practical use. for example, their arc length is expressive as a polynomial function of the parameter, and their offsets are rational curves
Ph曲線呈現出非常優良的實際應用價值，例如它的弧長可表示為曲線參數的一個多項式函數，其等距線是有理的。The motion of the two rotors with single - threaded, equal pitch trapezoidal profile was theoretically analyzed to eliminate the tooth interference
摘要本文針對無油螺桿式真空泵中一種常用的單頭等螺距梯形級齒的螺桿轉子型線，研究討論了二轉子級齒間的干涉問題。Not only was man now able to see with measured precision independently of visibility, but he could now “ see ” such objects as aircraft at ranges far in excess of those possible even under ideal optical conditions with normal vision
人不僅可以不受視線（能見度）的限制而看得很精確，並且可以「看見」諸如遠方的飛機等物體，其距離遠遠超過用正常的視力並藉助于最理想的光學儀器所能達到的。It compared some of linearization methods of platinum resistance ' s characteristic. it introduces a new subsection linearization method : unequal distance arithmetic, it improves the measure precision and decrease the calculation load. in the voltage and electrical current measure section, it use a measure chip which includes a / d conversion, dsp and arithmetic procedure, so it improves the mearsure precision greatly
