英文
repellency-
Bioassay on oviposition repellency of non - preferable plant extracts against citrus red mite panonychus citri
非嗜食植物提取物對桔全爪蟎產卵的驅避性測定In this study, precursors have been prepared by coprecipitation. the precursors prepared by coprecipitation have high purity, homogeneity and reactivity etc. thus it can decrease synthesis temperature and pbo volatility. furthermore the pyrochlore phase is hardly formed during synthesis
通過化學共沉澱法制備前驅體，使各組份能以原子尺度進行混合，提高反應活性，有效降低合成溫度，最大限度地減少鉛揮發造成的污染，同時避免焦綠石相的生成。In the actuation, the feeling measure and the balance compensation, the gyroscope used the electric capacity with the high sensitivity, the low energy consumption, and combined with the high quality factor characteristic of the resonance main body, which enable its system to have the quite outstanding performance : the vibration gyroscopes were generally used to measure the rotation rate, but because of axial symmetry factor, the axial symmetry vibrating - shell gyroscope can be used to measure not only the rotation rate but also the rotation angle, moreover do not bring the accumulation error as a result of the integral
該陀螺在驅動、感測與平衡補償上採用具有高靈敏度、低能量消耗的電容，並結合諧振體高品質的特性，有相當優異的表現:振動式陀螺儀一般都是用來感測轉速，而軸對稱殼式陀螺儀由於軸對稱的因素，不僅可以用來感測轉速，而且可以感測物體的轉角，並且避免了由於積分而帶來的積累誤差。This dissertation deals with the active vibration control strategy using the embedded piezoceramics as both actuators and sensors. with several ceramics embedded into the composite material structures during the manufacturing process without knowing the structural behavior in advance, this dissertation makes use of a self identification procedure to get the models of the system. apparently, the on - line self identification method enable people to update the models of system
另外本文利用埋入復合材料結構中的壓電傳感器和驅動器對其進行模型識別而得出結構的動力學模型，再將該模型用於控制器的設計，這樣做的好處是如果結構本身或者約束、環境等發生變化后，可以很方便地對結構的模型重新進行在線識別，及時更新控制參數，避免控制失效，而且不需要事先知道結構的其它屬性。And you should use only one drive per ide channel to avoid sluggish performance - a slave device, especially if it s also part of the raid - 0 array, will slow things down so much as to nearly eliminate any raid - 0 performance benefit
同時，為了避免降低性能，每個ide通道上只應連接一個驅動器- -從屬設備（尤其是當它也是raid - 0陣列的一部分時）對速度的負面影響幾乎會抵消raid - 0的全部性能優勢。For an ev drive system, the variation of rotor time constant will bring on variation of torque and exorbitant line voltage even the field orientation may be destroyed. the varied torque will affect ev dynamic performance, and the higher voltage will limit the output power due to the bound of batteries in ev
對于電動汽車驅動系統來說，轉子時間常數的波動會導致輸出轉矩和電機電壓的波動，並且嚴重時會導致系統出現振蕩，轉矩的波動會影響汽車的動態性能，電機電壓的波動則會由於電池電壓的限制而影響電機的輸出功率，這些都是電動汽車的驅動系統應該避免的問題。The main idea under controller design is damping model nonlmearities with control input to force the system dynamic into a linear sliding surface and utilizing dynamic filters to ensure the boundedness of states, inputs and outputs. the mismatched model uncertainties are suppressed with extra items in control input
Dsc控制器通過對消系統非線性項，將系統動態驅至線性滑模態；引入動態濾波器，確保系統的狀態及輸入輸出有界，同時避免了對非線性模型多次求導帶來的復雜性；在虛擬控制輸入中利用附加項來克服不滿足匹配條件的不確定性。A genetic algorithm was applied to select a favorable voltage for each task base on the time limit of task queue. by introduce to this system, about 40 - 50 % power dissipation was cut on average
提出一種任務驅動的功耗優化方法，在微處理器中，根據實際計算任務來調整性能，模擬結果表明可以避免約50的功耗浪費。分享友人
