The Euler angles could be expressed with arbitrarily large rotations.
这里欧拉角可以用来表示任意大的转动。
Compared to the Euler angles the main advantage of the quaternions expression of attitude motion is the avoidance of singular position in numeration procedure.
与欧拉角比较，姿态运动的四元数表达的主要优点是数值计算过程中不存在奇异位置。
The attitudes of vehicle are described by both quaternion and Euler angles, and two kinds of motion equations are established accordingly.
通过四元数法和欧拉角法描述飞行器姿态，并建立相应的运动学方程。
