In their summary, they state that this ape's vocal organ is not capable of producing delicately modulated or controlled sounds. 在他们的摘要中,他们说这类猿类的发声器官没法产生精美地调整及控制的声音。
In high frequency measurement ( 412Hz ), there is good linear relationship between the intensities of photoacoustic signal ( if not higher than 40 μ V ) and the modulated excitation source. In low frequency measurement, the linear relationship is ideal also. 在412Hz高频测定中,只要光声信号强度不超过40μV,光声信号强度与调制激发光强度之间有很好的线性关系,低频情况下线性关系也极为理想。
The means above is feasible not only to CW pulses, but also to frequency modulated and pulsatile modulated signal. It is adapt to tracking intelligent torpedoes with diverse signal types and passive tracking of active sonar signal. 上述方法不仅对CW脉冲信号可测向、测距,同样还适用于调频、跳频信号,所以可适用于信号形式多变的智能型鱼雷的弹道轨迹测量,以及主动声纳信号的被动跟踪。
The effect of perturbation period on friction is not evident. ( 2 ) After the loading perturbation was modulated to normal direction, the stick-slip rule was disrupted. 扰动周期对摩擦性状的影响不明显。(2)当在法向叠加载荷扰动后,标本固有的规则粘滑也被打乱。
