It included the bottom , which had inching and moving flapper of 5 pieces knifes side to side in the menu 菜单中有5把刀的左右点动和活动挡板左右点动的按钮。

Flapper is a young woman , especially one in the 1920 ' s who showed disdain for conventional dress and behavior 尤指19世纪20年代对传统的衣着和行为表示不屑的少妇。

The king he smiled eager , and shoved out his flapper , and says : " is it my poor brother s dear good friend and physician 国王更巴结地满面堆笑，伸过手来说： “这位是我那可怜的哥哥的好朋友医生吧？

The mock turtle sighed deeply , and drew the back of one flapper across his eyes . he looked at alice , and tried to speak , but for a minute or two sobs choked his voice 素甲鱼深深地叹息着，用一只手背抹着眼泪，瞧着爱丽丝想说话，可是有好一阵子泣不成声。

The torque motor received dc current signals from the electric control and applies torque to the single - piece armature and flapper which is supported on a torsion flexure 力矩马达接收来自电气控制器的直流电信号并将力矩施于由转矩挠曲支撑的整体式电枢及挡板。 ？

Hydraulic flapper - nozzle servo - valve is the most important component in hydraulic control systems . it is used very widely in industrial and aerospace application fields because of its high responding speed 喷嘴挡板伺服阀作为伺服控制元件,是闭环电液伺服控制系统中最重要的核心元件。
7.
In order to improve the reliability of servo system , a triplex electro - hydraulic servo actuator system with three torque motors , three jet flapper valves and three sets of feedback components is designed 摘要为了提高伺服作动系统的可靠性，设计了一种三余度的电液伺服作动系统，将伺服阀的力矩马达、喷嘴挡板阀、系统的反馈元件等做成一式三份。
8.
Therefore the output magnetic torque of torque motor can be increased . in this paper , mathematical model of hydraulic flapper - nozzle servo - valve is introduced . the mathematical model of magnetic fluid is built according to the reference introduction 本文给出了喷嘴挡板伺服阀的数学模型,对作用于伺服阀力矩马达的磁流体数学模型进行了推导,给出了添加磁流体的喷嘴挡板伺服阀的数学模型。
9.
But sometimes self - excited oscillations and noise may appear in hydraulic flapper - nozzle servo - valve if its construction is not selected very correctly . if self - excited oscillations and noise appear in hydraulic servo - valve , the performance of hydraulic control systems may lose stability 因它具有非常快的响应速度,所以是目前应用最广泛的伺服阀,但它也存在自激现象,容易产生自激噪声和振荡,严重影响伺服控制系统的稳定性。
10.
Well , there was mystery , the mock turtle replied , counting off the subjects on his flappers , - mystery , ancient and modern , with seaography : then drawling - the drawling - master was an old conger - eel , that used to come once a week : he taught us drawling , stretching , and fainting in coils “我们还学栗柿， ”素甲鱼丽着手指头说， “栗柿有古代栗柿和现代栗柿，还学地梨，还学灰花。我们的灰花老师是一条老鳗鱼，一星期来一次，教我们水菜花和素苗花。 ”
