無規噪聲 的英文怎麼說
中文拼音 [wúguīzàoshēng]
無規噪聲
英文
fluctuation noise-
Because of the using of interpolation, noise shaping and switching amplification in the digital audio amplifier technology, the power supply modulator is not only much efficient but also behaving good in envelope amplification, this advantage is hard to implemented with conventional technology
數字音頻功放技術是近年發展起來的高效率音頻放大技術,該放大技術採用了過取樣、噪聲整形等數字音頻處理演算法和開關功率放大。採用該技術實現的電源調制器不但具備很高的效率,而且能高指標地放大包絡信號,是常規的電源調制技術無法實現的。This dissertation only considers the signal ’ s distortion by interconnect, such as delay, reflection, discontinuity of microstrip, crosstalk and simultaneous switching noise, and so on. nowadays, there are some simulation software in pcb level, but they are lack of the well ability of modeling. in order to simulate the interconnect accurately, we have to make use of three - dimension full wave analysis method, whose disadvantage is low speed in computing, but is competent for developing rules in high - speed designs
目前也有一些針對這些噪聲的高速pcb板級模擬軟體,但它們都缺乏詳盡的建模能力,特別是當頻率逐漸提高和電路板日益復雜后,更是顯得無能為力,要精確地對互連結構進行分析,三維全波模擬器似乎不可缺少,其缺點就是速度慢,對整板模擬很難實現,但非常適用於規則開發,而這正好是本文除了建模與模擬方法研究外另一個重點。In the hardware implementation of a multi - channel active noise control system, the computational complexity is increased sharply when the number of filter coefficients and channels are increased
摘要在多通道有源噪聲控制系統的硬體實現中,當通道數目增大或濾波器長度較長時,常規的多通道演算法運算量急劇增加,使控制器可能無法實時實現。And national standard of home appliance washing machine ordain that the cleaning the containing water rate the using electricity the using water the noise and no malfunction using should be gotten up the national standard so the consumer does not fall in the trap and does not confuse the decision
魯建國說,家用電動洗衣機國家標準規定要求洗凈比含水率用電量用水量噪聲和無故障運行6項指標都要達到國家標準,可以看出,洗凈度是衡量洗衣機質量好壞的非常重要的因素。6 chang c c, cong j. pseudo pin assignment with crosstalk noise control. in proc. international symposiums on physical design, san diego, ca, april 9 - 12, 2000, pp. 41 - 47
雖然上述很多模型在計算電感上都比較精確,但是用於大規模計算時,計算復雜度太大以至於無法應用到布線過程的噪聲優化中。It should be noted that there is no requirement for industry in general to achieve the acceptable noise levels immediately, but to bring the noise level to or below the anl by the date specified on the noise abatement notice
條例並無規定各行業必須即時把噪音水平減至可接受的噪音聲級,但必須于消減噪音通知書訂明的日期前,將噪音水平減至可接受的噪音聲級或更低水平。The simulation results indicate that the parallel robot control can achieve much better effect than the traditional method by means of fuzzy control only if the abundant control experience and correct inference rules are available. as the simulation result showing, the anfis achieves the same satisfying effect with successful fuzzy control without requiring any control experience. the anfis can adjust the parameters of fuzzy inference system automatically and eliminate the influence of interfere signal on the base of adequate training samples
在缺乏實驗條件的情況下,通過對不同控制策略的模擬比較研究,說明了在具備系統的先驗知識和成熟的模糊規則的基礎上,對並聯機器人採取模糊控制能取得比採取傳統控制要好得多的效果,而anfis則能在毫無經驗的情況下,通過自動調整隸屬函數參數,自動建立符合系統變量特徵的控制模型和模糊推理規則,並能夠排除噪聲等干擾信號的影響,取得了與依賴專家知識進行控制一樣的效果,這也是模糊神經網路控制的優勢所在。Acoustics. noise emitted by machinery and equipment. measurement of emission sound pressure levels at a work station and at other specified positions. engineering method in an essentially free field over a reflecting plane
聲學.機械和設備排放的噪聲.工作站和其它規定場所聲壓級的測量.反射平面上基本無聲波場的工程測試法The system based on pid control theory has characteristics of fast response speed and higher peak overshoot, and it also has a good performance of tracking, but it is lack of ability of disturbance rejection. because smvs control method is insensitive to the variations of the model parameters, nonlinear and exterior noises, the attitude stabilization system designed based on smvs has fast response speed, higher ability of disturbance rejection and has no peak overshoot, namely, the system is robust
模擬結果表明,基於pid控制規律設計的系統具有響應速度快但超調大的特點,系統的跟蹤性能較好,但抗干擾能力較差;滑模變結構控制方法因為其對模型參數的變化、非線性和外擾噪聲的不敏感性,設計的聲納基陣姿態穩定系統無超調,響應速度快而且抗干擾能力強,具有很好的魯棒性。Reverberation room is the special test room that is used in acoustics, in the measurement of sound absorption coefficient in random incidence and determination of sound power levels of noise sources, the reverberation room is used very extensively
摘要混響室是聲學專業的實驗室用房,它在測量聲波無規入射時材料的吸聲系數和測量噪聲源的聲功率級中得到了廣泛應用。分享友人
