您要查找的是不是:
- negative acceleration motion 减速运动
- In the course of time positive and negative acceleration impulses tend to cancel one another. 在长时间中,正向和反向加速度冲击有互相抵消的趋势。
- If an arm is stretched forward under water resistance is increased and a reaction force backward is developed, both of which would contribute to negative acceleration. 如果手臂在水中是向前伸展则阻力会随之增加而向后方的反作用力也会出现,二者都会产生负加速度。
- This sequential action requires reciprocal even movements with the change of direction at each extreme of movement range requiring negative acceleration, stopping, and acceleration in the body roll. 这些连续的动作要求身体滚动时的减速,停止和加速阶段动作在接近结束时的换方向动作是彼此相反的。
- Objective:To study the effects of naloxone on the tail pain threshold and the content of enkephalin and dynophin in brain tissue in rats after alternating action of positive acceleration(+Gz)and negative acceleration(-Gz). 目的 :施加正、负加速度交替作用后 ,研究纳络酮对大鼠脑组织脑啡肽、强啡肽的含量及尾部痛阈的影响。
- And from this state of accelerated motion, it launches a nuclear missile. 是的。然后在这种加速运动的状态中发射核弹。
- When a swimmer slows and then finally applies forces there are stages of slowing down (the correct term is negative acceleration not deceleration) and speeding up (the correct term is positive acceleration not acceleration). 当游泳运动员慢下来然后增加力量以求得继续前进时会有不同的阶段,这就是减速阶段(正确用语是负加速度而非减速)和加速阶段(正确用语是正加速度而非加速)。
- A person who lives at the equator is in accelerated motion due to the earth's rotation. 一个居住在赤道的人由于地球自转的缘故是作着加速运动的。
- Sokolov: Yes. And from this state of accelerated motion, it launches a nuclear missile. 是的。然后在这种加速运动的状态中发射核弹。
- modified trapezoid acceleration motion 修正梯形加速度运动规律
- negative acceleration, negative G 负加速度, 负G
- When the velocity of a moving body changes continuously as the motion proceeds, the body is said to move with accelerated motion. 当运动物体的速度在其运动过程中不断地变化时,我们说该物体在作加速运动。
- The exponent of each item was discovered based on the optimizing the diagram factor, minimum radius of the cam curvature, maximum positive and negative accelerations of valve. 对于每一项的指数,则采用对气门运动加速度、丰满系数、最小曲率半径等优化的方法来寻求。
- This paper has solved problem of machining for the profile of the blade pump stator to improve trapezium accelerated motion regulation. 本文研究了叶片泵定子改进梯形加速度运动规律轮廓线型面靠模的加工问题。
- The beat signal model of the stationary, uniform motion and accelerated motion target is sinusoid, Linear Frequency-Modulated (LFM) signal and polynomial-phase signal (PPS) respectively. 静止、匀速运动和加速运动三类目标分别对应着正弦信号、线性调频(LFM)信号和多项式相位信号(PPS)三种差频信号模型。
- In an uniform accelerated motion experiment, the timing precision to record the moment a cart passes the measuring point can reach 10-4 S by Programmable Timer/Counter 8254. The experiment system can replace the traditional timing method. 在匀变速直线运动的实验中,利用可编程定时/计数器8254来记录运动小车过测点的时刻值,可使计时精度达到万分之一秒。 该实验系统可取代传统的计时方法。
- It is this molecular motion that we call heat. 就是这种分子运动我们称之为热。
- The meeting carried the motion by a large majority. 会议以多数通过了这项提议。
- He used his casting vote to block the motion. 他用他的投票反对动议的通过。
- The answer to my request was in the negative. 对我的请求的答复是否定的。
