Example Sentences:

	1.	The main contributions of the dissertation are as follows . in chapter 2 , the dissertation demonstrates the design of an airfoil model with a control surface driven by an ultrasonic motor as the actuator first , and then presents the experimental modeling of the actuator 论文的主要工作与学术贡献如下: ( 1 )设计了以超声电机为作动器驱动控制面的二维翼段模型,并建立了作动器的传递函数模型。
	2.	The dissertation presents the combined theoretical , numerical and experimental studies on the experimental modeling of the actuator , the design of test rig and control system , the modeling of two - dimensional airfoil aeroelastic system , the control design of active flutter suppression , and the effect of group delay in the digital filter on the stability of aeroelastic closed - loop system 本文通过理论分析、数值仿真与风洞实验相结合的方法,研究了超声电机作动器建模、翼段颤振实验装置和控制系统设计、二维翼段气动弹性系统建模、颤振抑制控制律设计以及数字滤波器群时延对颤振抑制闭环系统稳定性影响等问题。
	3.	Firstly , the airfoil ' s classic flutter ( at small attack angle ) , stall flutter ( near the static stall angle ) and response ( at large attack angle ) are analyzed . it is found from the numerical results that " lock - in " will occur at certain freestream velocity range near the static stall angle , where the frequency of the vortex will be equal to the natural frequency and the flutter has the characteristic of self - induced oscillation . when the attack angle is far from the static stall angle , the vortex will have its own frequency , which differs from the natural frequency , and the flutter has the characteristic of forced oscillation 首先研究了二维翼型的古典颤振(小攻角) 、失速颤振(失速攻角)和动力响应问题(大攻角) ，得到以下结论：在静态失速攻角附近的一定来流速度范围内，分离涡会发生频率锁定现象，分离流的频率与固有频率趋于相同，这时的振动呈现自激振动的特点；远离失速攻角时分离流频率则摆脱固有频率的影响，此时的振动具有强迫振动的特点。
