加加速度 meaning in English

jerk

It will produce very big angular velocity , angular acceleration and angular jerk when tracking fast moving targets . this may lead bigger tracking error and fail to track targets
目标速度的提高将会产生大的角速度、角加速度乃至更大的角加加速度，导致光电经纬仪电视跟踪动态误差急剧增大，目标逸出视场，跟踪失败。
Under these assumptions , three kinds of excitations , namely , harmonic force with frequency equal to the structural fundamental frequency , harmonic force with frequency equal to half of the structural fundamental frequency and pulse force are inputted to the undamaged and damaged structures . then under the same excitation , the undamaged structural displacement responses , velocity responses , acceleration responses , jerk responses and responses of integrated displacement are compared with that of the damaged ones
在此假定基础上,分别将激励频率等于结构基频的简谐形激励、激励频率等于结构基频之半的简谐形激励和锤击激励输入结构,而后比较了损伤前后结构在相同激励下的位移响应、速度响应、加速度响应、加加速度响应和位移积分响应。
