Among all the skills, the following constitute a special attractive style in xiao hong ' s novel, which are a demonstration of xiao hong ' s discovery and development in her novel language as well, such as, complicated narration " against with concision ", " contrary narration of implication instead of superficial semantics, intended a " aberrational " organization of sentences, circumbendibus of meanings and flavors with artful organization of sounds and rhythms, and etc
其中，與簡潔「背道而馳」的繁復敘述，以內在含義扭轉表層語義的「悖反敘述」 ，有意「越軌」的句子組合方式，以及巧借聲韻的婉約傳達意味與情趣等特點，構成了蕭紅後期小說文體的獨特魅力，也顯示了蕭紅在小說語言藝術上的探索與變化。To sum up, tested and validated by data sets of shenzhou iv unmanned spacecraft and precise orbit ephemeris, the algorithms presented in the thesis can improve orbit accuracy and reduce random noise considerablely. derived conclusions have important value for reference, and lay the firm technological foundation for future applications
總之，經過神舟四號飛船實測數據計算和精密星歷檢驗，表明本文提出的各種定軌方法可以較好的提高定軌精度，減少隨機噪聲，所得出的結論對于實際應用具有重要的參考價值，並為將來的應用奠定了堅實的技術基礎。M - mode is a kind of dynamic display mode. it also uses the brightness to represent the strength of the ultrasonic returns, but the independent variable in the display is time. returns from different scanned depths are revealed along the time axis to show the movement of different layers of the scanned organs
M型是一種運動顯示方式，它也是以亮度的強弱來表示回聲信號強弱，但將聲束路徑上不同深度的回波圖象沿時間軸慢慢展開，以表示界面的運動軌跡。We can take molecular motor as a brownian particle in the case of ignoring the conformational changes. the interaction between motor and microtubule can be described by a special potential function and the effect of the environment can be simplified as a noise
在不考慮分子馬達構象變化的情況下，通常把分子馬達抽象為布朗粒子，用一個特定的勢函數來表示軌道與馬達的相互作用，環境的影響可以簡化為特定形式的噪聲激勵。The results show that the wayside noise increases 8db - 12db, if the train ' s velocity increase two times ; and increases 3 db, if the number of axles increase tow times ; and decreases 3db, if the distance far away from the track increase tow times damping loss factor increases, the wayside noise decreases ; coupling loss factor increase, the wayside noise increase
預測結果表明：列車通過時，在其他條件不變的情況下，列車速度增加一倍，輪軌輻射噪聲大約增加8db 12db ；列車軸數增加一倍，輪軌輻射噪聲大約增加3db ；預測點距軌道距離增加一倍，輪軌輻射噪聲大約降低3db 。Ultrasonic motors are a new kind of solid actuators that come into being since 1980 ’ s, which use inverse piezoelectric effect of pzt to excite stator ’ s elliptical vibration and produce driving power by frictional coupling
超聲波馬達是上世紀80年代開始發展起來的一種新型驅動器，它是利用壓電陶瓷的逆壓電效應激勵出定子表面質點的橢圓軌跡振動，依靠摩擦耦合來實現驅動。Noise radiated by the rail vibration is considered to be the main portion of wheel / rail noise in the frequencies blew 3000hz
研究表明， 3000hz以下的輪軌噪聲中由鋼軌振動產生的輻射噪聲占輪軌噪聲的70 %以上。The wheel - rail noise is generated by vibration that is caused by the surface roughness of wheel - rail
而鐵路輪軌噪聲產生的根本原因是由輪軌間表面粗糙度引起的振動而造成的。Simulations show that this method can quickly and accurately recognize the object in input image and has a few strong robustness against noise in the input image. secondly, the simulations for two kinds of control algorithms based on pd, namely, direct pd control and pd control with feedforward compensation, have been completed in this thesis. simulations show that both control algorithms have good control performance in tracking a known trajectory and the effect of dynamic compensation of pd control with feedforward compensation is obvious
本文首先根據二值圖像的特點結合距離變換提出了一種基於ga模式匹配的復雜背景下目標的識別方法，該方法能快速準確的匹配圖像中的目標，而且對噪聲有較強的魯棒性；接著對基於pd的2種機器人控制演算法（直接pd控制和pd加前饋補償控制）進行了模擬研究，實驗結果表明這兩種pd控制演算法都具有較好的軌跡跟蹤性能，而且pd加前饋控制的動態補償效果也很明顯。Experimental method is used to study the relation between vibration of different position and noise and design a new simple and practical method but the method of treating whole rail as euler or timoshenko beam which is widely used by the most experts, but the result is improved to be effective
對加工出的鋼軌阻尼吸振器實物進行效果分析試驗，結果表明:鋼軌阻尼吸振器減振降噪效果顯著。本文研究鋼軌各部位振動特性及其與噪聲之間的關系，設計出兩方向的鋼軌阻尼吸振器，經實驗驗證效果顯著。分享友人
