侧向扰动 meaning in Chinese

lateral disturbance

It is also introduced the task and composition of the system . secondly , in order to studying the dynamic characters of the bomb , the vertical and side direction perturbation equations of the bomb are analyzed . moreover , the transfer functions of the bomb are identified
第二，为了研究弹的动态特性，利用小扰动法将微分方程线性化，得到弹体纵向、侧向扰动方程组，用系数冻结法推导出简易制导炸弹的传递函数。
The forces and moments acting on the bomb are analyzed and the corresponding reference frames and motion model are built . based on disturbance theory , the mathematical model is simplified . what ' s more , taking real flight of the sgb into account , some assumptions are given . on the basis of these assumptions , the motion of the sgb is broke into the motion in vertical plane and the motion in the horizontal plane . dynamic characteristics of the motion in vertical plane is mainly studied
在此基础上，通过小扰动理论将简易制导航弹的空间运动数学模型化简，得到简易制导航弹的空间扰动运动数学模型。根据简易制导航弹的实际飞行情况，作出了一些假设条件，将简易制导航弹的空间扰动运动分解成纵向扰动运动和侧向扰动运动，并相应的得到两个通道的数学模型。
