振动角 meaning in Chinese
angle of oscillation
Examples
- Vibration of tank gun in the process of firing is one of the main factors that affect its firing accuracy , especially the instantaneous angular motion and the instantaneous linear velocity at the point of gun muzzle when the projectile leaves the barrel bore
影响坦克炮射击精度的主要因素之一是火炮振动，起关键作用的振动分量是在弹丸出炮口瞬间炮口振动角位移和横向线速度。 - ( 2 ) . according to the system indices and requirements together with the technology characteristic , it researches the capture possibility of apt capturing system . then it introduces the common scan methods , such as raster , spiral , raster spiral , rose and lissajo . ( 3 ) . it makes a detailed simulation analysis of the raster and spiral scan , analyze the connection between capture probability , capture time , system index at different capture resolution angle , capture range , vibration angle extent and terminal location distributing mean square deviation
其中对几个关键部分进行了详细分析:计算了目标角反射器的激光雷达散射截面( lrcs )值,研究了qd与ccd对目标位置角度的计算方法和空间分辨率; ( 2 )根据系统指标和要求并结合现有国内技术特点研究了apt捕获系统扫描的捕获概率问题,然后分析了几种常见的扫描方式:矩形( raster )扫描、螺旋( spiral )扫描,矩形螺旋( rasterspiral )扫描,玫瑰形( rose )扫描以及李萨如形( lissajo )扫描; ( 3 )对分行扫描和螺旋扫描进行了详细的仿真分析,分析了它们在不同捕获分辨角、捕获范围、振动角振幅和终端位置分布均方差时的捕获概率、捕获时间与系统常数之间的关系。
