frequency restriction 中文意思是什麼

frequency restriction 解釋
頻率限制
  • frequency : n. 1. 屢次，頻仍，頻繁。2. （脈搏等的）次數，出現率；頻度；【物理學】頻率，周率。
  • restriction : n. 1. 限制，限定。2. 拘束，束縛；自製。3. 【邏輯學】限定。
  1. Restriction enzymes and dna probes are used to determine the exact sequence, but it is possible to get a rough estimate by analyzing the frequency of recombination between the alleles of linked genes

    雖然可以利用限制性內切酶和dna探針精確的分析出特定序列，但是在分析連鎖基因等位基因間的重組序列時，會出現不準確的估計。
  2. The results prove that df could simplify the solve process and its shortcoming of restriction in approximately denotation, frequency unitary 1 and inapplicability in more commonly quadratic system are also shown at the same time

    結果證明：使用描述函數法能夠簡化該問題的求解，但也暴露出其存在著近似表示，頻率歸1以及更一般二階系統不適用等方面的局限和不足。
  3. Through the review of theories about capital structures of foreign countries, the paper compares developed with developing countries in the capital structures and analyzes the character of chinese listed company. based on ample data, the proportion of equity financing is much more than that of credit financing in the capital structure of listed company. it indicates that listed company ' s choice of financing approach has an intensive predilection of equity financing, which is far from “ pecking order ” of financing approach in matured market. at the same time, the efficiency of equity finacing is not hight, so is debt finacing. the funds raised from equity finacing changes high frequency and lacks restrict, and the efficiency of debt finacing from bank is not hight because of “ soft restriction ”. despite the debenture has a preferable restrict, it grows lentitudily in china

    大量數據說明中國上市公司融資結構中股權融資的比重遠遠超過債權融資，與成熟市場條件下公司融資方式的「啄食順序」不同，有著強烈的股權融資偏好。同時，中國上市公司的融資效率是低下的，不管是股權融資還是債權融資。股權融資募集資金變更頻繁，缺乏約束，資金使用效率不高;銀行債權融資存在軟約束，使用效率同樣不高;公司債券融資具有較高的約束力，但在我國發展受到限制。
  4. This method is easy to implement and has no restriction on array geometry and sensor patterns ; three methods for the design of broadband frequency invariant beamformer are proposed, which are the method of resampling signals received by the array, the dft ( discrete fourier transform ) interpolation method and adaptive synthesis method, respectively. examples and performance analyses are given for each method ; a simplified linear constrained minimum variance broadband adaptive algorithm that based on dft interpolation method is presented. compared with conventional broadband adaptive algorithms, the presented method can reduce computation work greatly

    提出了一種簡單、易於實現的恆定束寬波束形成器設計方法，該方法對陣形和陣元指向性沒有任何限制；分別提出了基於陣列接收數據重采樣、基於dft插值和自適應綜合的三種具有頻率不變波束圖的寬帶波束形成器設計方法，對于每一種設計方法都給出了一個設計實例並做了性能分析；提出一種基於dft插值的簡化線性約束最小方差寬帶自適應陣列演算法，該方法可以大大降低自適應陣列的運算量。
  5. Because the different stiffness match of front and rear suspension is very influencing to the ride comfort, optimal model of ride comfort is developed, regarding the rms of driver ’ s acceleration as the objection, regarding the stiffness of front and back suspension as optimal variable, regarding quiet flexibility 、 dynamic flexibility 、 frequency and dynamic load as nonlinear constraints. by matlab program and using sqp, the optimal match of front and back suspension ’ s stiffness is achieved, this optimal model consider not only request of quiet 、 dynamic flexibility 、 frequency and damp, but also security of run and peace of road, it is closer to the fact than other models which only consider partial restriction

    由於前後懸架垂直剛度的不同匹配對汽車行駛平順性影響較大，論文建立以駕駛員垂直加速度的均方根值作為汽車行駛平順性優化目標值、以前後懸架垂直剛度作為優化變量的優化設計模型，並輔以靜撓度、動撓度、頻率、動載荷等非線性約束，使用序列二次規劃法，利用matlab編制優化程序，求得前後懸架垂直剛度的最優匹配值;此優化模型不僅包含動靜撓度及頻率和阻尼的限制，還考慮到汽車的行駛安全性和道路友好性，比文獻報道的只考慮部分約束的優化模型更切合實際情況。
  6. For each high frequency affix head, its morphological rules are automatically derived. the semantic types of their modifiers are obtained as the restriction on the rules for compounds. then the propriety of an unknown compound is estimated by the similarity measure between the semantic class of its morpheme and the semantic restriction posted in the respective rules

    我們以復合詞為例，從語料庫中，自動抽取各類復合詞中的詞干意類，用以訓練規則，透過比對一未知詞詞干意類與規則意類間的相似度，判斷其是否為合理的復合詞。
  7. In this thesis, the signal express format and characteristic of pulse internal phase modulation and pulse external frequency agile is introduced, and the signal design is processed based on the demand of radar system, the restriction of parameter design and various code format

    本文首先介紹了脈內調相脈間跳頻信號的表達形式和特點，並根據雷達系統的需求和參數設計的約束條件以及不同的編碼形式進行了信號的設計。
