The calculation of these velocity and displacement curves from the accelerogram is not a trivial matter . 要从加速度记录计算速度和位移曲线也不是一件轻而易举的事。
Statics treats of special cases in which the acceleration is zero, and kinematics deals with motion only . 静力学是研究加速度为零的特殊情况,而运动学只讨论物体的运动。
Nothing was said in the preceding discussion regarding the units in which force, mass, and acceleration are to be expressed . 在前面的讨论中,没有提到力、质量和加速度的单位。
The bail connecting the most inferior gimbal axis to the next gimbal axis mounts the meridian accelerometer . 把最里面的框架轴与第二框架轴连接在一起的框架上安装了子午线加速度计。
In the absence of ground acceleration data, the nature of the input excitation can be inferred only from structural behavior . 在没有地面加速度数据的情况下,只能从结构的性状来推测输入激振的性质。
On the newtonian theory, for instance, acceleration varies with distance, but distance also varies with acceleration . 例如根据牛顿的理论,加速度随着距离的不同而变化,但距离也随着加速度之不同而变化。
Even for the most recent destructive earthquakes in the world there has been a lamentable lack of measured ground acceleration data . 即使不久前世界上发生的大地震,也十分遗憾地没有测到地面加速度数据。
The outputs of these accelerometers are the three coordinates of the inertial velocity of the vehicle with the exception of gravity effects . 这些加速度计的输出是三个没有重力影响的飞行器惯性速度座标。
For this reason, considerable testing is done on such devices as centrifuges to determine linearity of sensitivity to acceleration . 为此,大量的测试要在离心机装置上进行,以确定对加速度灵敏度的线性度。
Hence, the pendulum is overcorrected during the initial stages of an acceleration and is undercorrected immediately following an acceleration . 因此,在加速度开始作用阶段校正量过大,而在加速度作用过后校正量不足。
