- The sun disturbs the elliptical motion of the moon around the earth .
月球繞地球的橢圓運(yùn)動(dòng)受到太陽的干擾。 - Yet there is also some elliptical motion to this general trend
可是，在總體趨勢上仍然有一些橢圓形的運(yùn)動(dòng)。 - Being a sort of new principle micromotor in the fronitier of science , the ultrasonic motor ( usm ) is developed at recently twenty years . utilizing the stator surface particle elliptical motion excited by piezoceeramics , the usm is drived by friction force between the stator and rotor
本文以這一新型電動(dòng)機(jī)為研究對象，對其運(yùn)行特性和控制策略進(jìn)行研究，是有較重要的理論和實(shí)際意義的。 - Being a sort of new principle micromotor in the fronitier of science . the ultrosonic motor ( usm ) is developed at recently twenty years . utilizing the stator surface particle elliptical motion excited by piezoceeramics , the usm is drived by friction force between the stator and rotor . compared with the conventional electromagnetic motor , the ultrasonic motor has the following features : high speed , high holding torque when power is off and so on . because of it ' s characteristics , the ultrasonic motor has obtained some widespread application in robots , precise instrument , house electronical appliance , sapceecraft automobile and micromechanism
超聲波電機(jī)( ultrasonicmotor )是近二十年來發(fā)展起來的一種新原理電機(jī)，其原理不同于傳統(tǒng)的電磁型電機(jī)，它是利用壓電陶瓷的逆壓電效應(yīng)使定子的表面質(zhì)點(diǎn)產(chǎn)生橢圓運(yùn)動(dòng)，通過定子和轉(zhuǎn)子之間的摩擦力驅(qū)動(dòng)轉(zhuǎn)子運(yùn)動(dòng)。這種新型的電機(jī)與傳統(tǒng)電磁電機(jī)相比，具有響應(yīng)快、不受電磁干擾、結(jié)構(gòu)緊湊、低速、大扭矩、斷電自鎖等優(yōu)點(diǎn)，因而在微型機(jī)械、機(jī)器人、精密儀器、家用電器、航天器、汽車等方面顯示出廣泛的應(yīng)用前景。 - It's difficult to find elliptical motion in a sentence. 用elliptical motion造句挺難的
