Input matrix of state equation G ( k) for constant angular velocity model and constant angular acceleration model was presented separately. 对等角速度模型和等角加速度模型的状态方程输入矩阵G(k)进行了计算。
In contrast to the activation effect of constant angular velocity rotation, constant angular acceleration had an inhibition effect on the cognitive processes and this inhibition effect may have several levels. 结论匀速旋转对晚期选择注意加工有激活作用,相对于匀速旋转,匀角加速度旋转对选择注意加工有抑制作用,这种抑制作用有几个层次。
In the paper, we expound the mechanical principle of a yo-yo and analyze the process of its motion by systematic theory. We conclude that its translation is the perpendicular rectilinear motion with constant angular acceleration, its rotation is the one with constant acceleration. 本文阐述了溜溜球的力学原理,并对其运动过程进行了系统的理论分析,从中得出其平动为匀变速垂直运动,转动是匀变速转动。
By Beans of the conservation laws of angular momentum and energy for a charged thin spherical shell with constant angular acceleration in electromagnetic field is investigated, torque and the power of external force are calculated separately. 对均匀带电薄球壳匀加速旋转问题,由电磁场的角动量定恒守律和能量守恒定律两种方法分别得出了外力矩及其功率的正确结果。
Conclusions It is suggested that vestibular stimuli from constant rotation and rotation with constant angular acceleration exert different effects on auditory cognitive activities: constant rotation quickens the auditory cognitive activities, while rotation with constant angular acceleration inhibits the auditory cognitive activities. 结论匀速旋转和恒角加速度前庭刺激对人体听觉认知活动效应明显不同:匀速旋转加快听觉认知活动,而恒角加速度抑制听觉认知活动。
The paper focuses on the analysis on Model 2K-H Planetary Mechanism Soft Start System and deducts the characteristic relationships of torque, angular speed, power of input axle, inner gear, output axle and loads using constant acceleration start and sine angular acceleration. 着重对2K&H型行星机构软起动系统进行分析,推出了输入轴、内齿轮、输出轴的力矩、角速度、功率与采用等加速度起动和正弦角加速度起动负载的特性关系。
