中文拼音 [fēiguīlíng]
非歸零
英文
non-return to zero （nrz）-
The schedule of this kind of production can be formulated as assigning n parts to m machines. to find the optimal solution is an np - complete problem in theory
該類生產的調度可歸結為n種零件需經m類機器加工的復雜非流水型作業系統的排序問題。The fundamental problems are boiled to zero eigenvalue solutions and all their jordan normal form and non - zero eigenvalue solutions
將問題歸結為零本徵值本徵解和非零本徵值本徵解問題。This immediately tells us that the virtual quanta necessarily have to be short lived. thus the vacuum has a non - zero and very large value of energy density associated with it
能在極短時間內復歸于無，在不違反能量時間測不準定理的情況下，短暫的能量不守恆是容許的，所以真空可擁有一個非零而非常大的能量密度。The research for key techniques of turbo codes is processed. it includes, ? the design of optimal component codes and the performance of asymmetric turbo codes are analyzed ; ? a search algorithm for short random interleaver based on the distance spectrum and ids criteria is carried out and simplified ; ? random puncturing method to improve the weight distribution of turbo codes with some special code rates is analyzed and simulated. ? the effect of different schemes of trellis termination to the performance of turbo codes is analyzed ; ? a new low complexity decoder structure is provided ; 5
對turbo碼的部分關鍵問題進行分析和改進，主要包括： ?分析了最優分量碼的設計和非對稱turbo碼的性能； ?設計了基於距離譜和ids的短隨機交織器搜索演算法並進行了簡化； ?提出了採用隨機刪余方式改善特定高碼率turbo碼重量分佈特性的方法； ?分析了不同編碼器狀態歸零方案對turbo碼性能的影響； ?提出了一種降低實現復雜性的turbo迭代譯碼器結構。And then, a state equation is set up by the relationship among the input and output characteristic vectors as well as the state matrices ( sms ). the non - zero element in the sms characteristic is taken according to taylor series expansion, which is a transfer function of the basic mechanical unit
再次，闡述了狀態變換矩陣的形成過程，通過泰勒級數展開，提取其非零元素的特徵，並按照傳遞特徵值對基本變換單元加以分類，歸納了狀態變換矩陣的性質。Nonreturn to zero code
非歸零碼The use of wave packet to analyze the dynamics of quantum mechanical systems is an increasingly important method to the study of the classical - quantum correspondence. using the quantum gaussian wave packet analysis method, we calculate the autocorrelation function of the rectangular billiard, the peak positions of the autocorrelation function match well with the periods of the classical periodic orbits, which show that the period of the classical orbits can be produced by the time - dependent quantum wave packet method. we also discuss wave packet revivals and fractional revivals in the rectangular billiard, the results show that there are exact revival for all wave packet at each revival time. we find additional cases of exact revivals with short revival times for zero - momentum wave packets initially located at special symmetry point inside the billiard
利用波包分析量子力學體系的動力學行為在研究經典和量子的對應關系方面越來越成為一個非常重要的方法.利用高斯波包分析方法，我們計算了矩形彈子球體系的自關聯函數，自關聯函數的峰和經典周期軌道的周期符合的很好，這表明經典周期軌道的周期可以通過含時的量子波包方法產生.我們還討論了矩形彈子球的波包回歸和波包的部分回歸，計算結果表明在每一個回歸時間，波包出現精確的回歸.對于動量為零的波包，初始位置在彈子球內部的特殊對稱點處，出現一些時間比較短的附加的回歸Nonpolarized return - to - zero recording
非極化歸零記錄Though the compilation work on volume two was not as difficult as on volume one, it was nevertheless a hard slog. this was due to the scarcity of basic research materials. the great bulk of our information was sourced from newspaper advertisements and isolated bits of published film information gleaned from reviews
大全第二卷資料搜集和整理工作，雖然沒有第一卷那麼艱辛，可是仍然非常困難，因為有關的基本資料和參考資料實在不多，極大部份仍須從廣告及零星的影訊影評中歸納整理出來，因此並不算完整，希望今後能發現更完整的資料，作補充和更正。分享友人
