起動脈沖作用 的英文怎麼說
中文拼音 [qǐdòngmàichōngzuòyòng]
起動脈沖作用
英文
starting-pulse action-
With dispersion, xpm can induce intensity fluctuations and timing jitter of the pulses in the receiver. it can also cause the spectral spreading of the channel so that crosstalk is introduced. all these effects put a tight limit on the capacity of the systems
它與色散共同作用,會導致接收端光脈沖的變形(強度起伏) 、光脈沖的時間抖動以及通道的頻譜擴展,這些後果都會限制系統的性能。The fast - ignition technique is more like a petrol engine : first the fuel is compressed and only then is it ignited by a second laser pulse ? acting as a spark plug ? that is fired through a hole in the pellet
快速點燃法更象汽油發動機:首先壓縮燃料,此後才通過燃料球上的一個小孔,用第二的激光脈沖發射器發射激光? ?起點火器的作用? ?將其點燃。Calculations indicate that the carrier phase takes effect till the time width of the pulse envelope becomes smaller than the period of the carrier oscillation, and the interpretation of this phenomenon is also presented. it is the difference between phase delay and group delay that causes the sliding between the carrier and the envelope
數值分析的結果表明,當脈寬小於光波周期時,相位的作用開始顯現出來,當脈寬比光波周期長時,載波相位的作用可以忽略,並分析了相位起作用的原因,用解析的方法說明正是相延遲和群延遲之間的差別造成了光載波在脈沖包絡下的滑動。We believed that laser manipulation of a bubble might present a way to control the dynamic process of the bubble and clarify the origin of single - bubble luminescence. - especially, the liquid - to - vapor phase transition of a micro system ( such as a vapor bubble ) could be studied by using our method
最近,本研究組提出利用紅外激光產生的熱鑷作用於動態空泡思想,並成功實現了利用熱鑷操縱脈沖激光產生的單個動態空泡,分析了熱鑷的起源,研究了空泡相變的動力學過程。Regard how to structure the control system of sensorless bldcm with dsp - tms320f240 as the centre in this paper, the detailed argumentation course of the motor startup, bemf terminal voltage measurement and control strategy is given out, give and pay concrete details for the software and hardware realization and experimental result. in order to treat the bldcm control system with dsp clearly, the full paper divides into six chapters altogether : chapter one, introduceing the development course, the structure characteristic and operation principle, etc. of bldcm in the introduction ; chapter two, directed against the startup issue of bldcm, the chapter give and publish the rotor measure pulse orients technology for motor startup in detail ; chapter three, proceed with mathematics model of the bldcm, expounding the control schemes ; chapter four, two important devices introducing : dsp ( 240 tms320f ) and power invertor control chip ( ir2131s ) ; chapter five, give and publish the detail of hardwares of control system ; chapter six, by ccs ide of ti, realize the control schemes in the front chapters with software, offere the procedure flow chart of main subroutine and some key place of programming, the experiment result in addition
全文共分六章:第一章、緒論中介紹了bldcm的發展歷程、電機本身的結構特點和工作原理等;第二章、針對五位置傳感器bldcm的起動問題,文中詳細給出了檢測脈沖轉子定位起動技術;第三章、從電機的數學模型入手,詳細論述了反電動勢端電壓法和系統的控制策略;第四章、介紹了硬體實現中的兩個重要器件: dsp ( tms320f240 )和功率管逆變器控制晶元( ir2131s ) ;第五章、詳細給出了控制系統的硬體實現細節;第六章、利用ti提供的ccs集成開發環境,將前面章節的控制方案用軟體加以實現,給出了主要部分的程序流程圖和一些編程要點以及實驗結果。Vibration of microscale beam resonator induced by laser pulse
激光脈沖作用引起的梁形微諧振器的振動In this paper, we design two types of flexible hinge, which are column stagger flexible hinge and flat straight round flexible hinge. the control system of the drive equipment includes the unity of the central console and control module. the console regards vc + + 6. 0 as the tool, it can set pulse number and pulse speed, start and stop the electromotor
微驅動裝置的控制部分由上位機和控制模塊組成,上位機採用vc + + 6 . 0編制控制界面,可以設置電機旋轉所需的脈沖數和脈沖速度,可以實現電機的起停,正反轉及脈沖清零等工作,還可以分別控制不同鏡架的電機及相同鏡架的兩個電機。分享友人
