查询词典 acceleration of gravity

In this paper, the principle of the accelerometer-based gravity gradiometer is presented and its measurements formulas are derived using the basic equation of acceleration in a rotating body.

然后以美国Bell/Aero公司生产的重力梯度仪为例，导出旋转加速度计式重力梯度仪测量结果。

The explanation is that the 'gravitational field' created by acceleration is added to, or subtracted from, the gravity of the Earth.

这个问题的解释就是由加速而需在地球引力场的基础上增加或者减少的"重力场"。

Physical pendulum ; period ; reconcilable pendulum ; radius of gyration ; acceleration of gravity

Afterwards, we propose a new constant coefficients measurement method in dynamic equation of robot manipulators, this measurement method includes three groups of experiments: group one, let each joint of robot manipulator keep static to measure the constant coefficients in gravity term of dynamic equation and Coulomb frictional torque, group two: let only one joint of robot manipulator move at a constant velocity to measure the viscous frictional coefficient and constant coefficients in effective inertia of dynamic equation, group three: let only one joint of robot manipulator move at constant acceleration at a time to measure constant coefficients in Coriolis and centrifugal term and coupling inertia of dynamic equation.

让操作器单个关节恒速运动，在对驱动系统中传动机构，减速装置和电感系数综合考虑的基础上，这组实验对粘滞摩擦系数及有效惯量中常数系数进行测量。这种测量方法只要求旋转关节的驱动电机施加恒定电压，回转关节驱动电机施加正弦波电压。3。让操作器单个关节恒加速运动，这组实验测量动力学方程中哥氏力、离心力项和耦合惯量项中的常数系数，这种测量方法只要求单个关节匀加速运动，而其它各关节保持静止，这种测量方法虽然要求关节匀加速运动，但不必进行关节角加速度检测，而只需进行关节角位移和角速度检测即可，输入量直接给定为输入电压。

On the basis of a previous work which has proved that the inertial mass can produce gravity, and the magnitude of which is inversely proportional to the square of the distance of the two bodies, it is discussed that whether bodies with different densities fall with the same acceleration.

在理论上证明惯性质量会产生万有引力，并在万有引力与距离平方成反比的基础上，讨论了不同质量密度的物体在引力场中自由下落加速度的问题。

Hence, new physics would take into consideration at least one of three possibilities: clock acceleration, a modification of the law of gravity, or modified inertia.

因此，新的物理原理可能至少是这三种可能性之一：时钟加速，修改引力定律或者修改惯性。

Meanwhile, analysis of the acceleration of pulses from a binary pulsar by radio astronomer s at the University of Massachusetts in Amherst in 1978 provided indirect evidence of gravity waves

与此同时，1978年阿默斯特市马萨诸塞大学的射电天文学家们对来自双脉冲星的脉冲的加速度所作的分析，也提供了引力波的间接证据。

An anomalous gravity acceleration difference variance of (1～2×10〓g) was observed with preliminary 10m-droppinglength experiments, but it is independent upon the rotation sense of the test mass.

近10m长距离自由下落初步实验表明在两检验质量自由下落过程中，出现了有规律的重力加速度差异常变化现象。

We spread the feeling machine to study the simple pendulum vibration period with a 霍 of switch 尔, perfect the diagraph of the gravity acceleration;We will gather a 霍 of switch 尔 spreads the feeling machine to used for measuring the spring coil to flap the son makes JIAN3 XIE2 vibration of period, further tested to find out inertial quantity of the object;New gather a 霍 of switch 尔 spreads the feeling machine to provided a kind of precision to measure the 磁 damping coefficient and new method of the glide coefficient of friction of the materials that the magnetism slips the piece for us;Gather a 霍 of switch 尔 spreads the feeling machine and can also used for the verification machine can guard the 恒 laws etc.

我们传布了感觉机器用开关尔的霍学习简单的钟摆震动时期，使地心引力加速的分度尺完美；我们将会聚集开关尔的霍传布感觉机器到为测量要拍打儿子的卷作时期的 JIAN3 XIE2 震动的春天用，更进一步测试发现物体的不活泼的量；新的聚集开关尔的霍传布感觉以机器制造提供一种精密测量磁湿气磁性滑倒块的材料摩擦的滑动系数的系数和新的方法因为我们；聚集开关尔的霍传布感觉机器和罐子也用因为确认机器能及其他保卫恒法律。

The bodily center of gravity speed changes along the changing of the swivel posture. In the three axes of X, Y, Z, the speed is pindling and has no appearance difference in the front-to-back direction and left-to-right direction, but speed in the vertical direction is the fastest.The speed of the swinging leg appears three acceleration stages obviously.

在身体转动中无论手臂的引带、跟随或摆动腿的挥摆等动作，正好体现了肢体相对身体纵轴质量分布的改变，从而达到了调整身体转动速度的目的，所以古典芭蕾舞挥鞭腿转720度难度动作是满足动量矩守恒定律的。4。
