您要查找的是不是:
- 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。
- 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)。
- negative acceleration, negative G 负加速度, 负G
- 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。
- The acceleration is positive if the speed is increased, negative if speed is decreased. 速度增加的加速度为正加速度,速度减少的加速度为负加速度。
- The answer to my request was in the negative. 对我的请求的答复是否定的。
- His answer to my request was a negative. 我的请求遭到了他的拒绝。
- The tests for hepatitis were negative. 肝炎检查结果是阴性。
- An instrument used to measure acceleration. 加速计,测震仪用于测量加速度的仪器
- Their criticism was not negative. 他们的批评并不是负面的。
- Do a blow-up of this corner of the negative. (对某事的)详尽的报道。
- Variation of NO,NOS level of brain tissue and plasma ET in rats induced by positive and negative acceleration 正、负加速度交替急性大鼠脑组织NO、NOS及血浆ET的含量变化
- I have a negative opinion on the value of this idea. 我对这个主意持反对意见。
- How many copies do you ask us to print off from the negative? "用那张底片,你要我们印几张像片?"
- The system undergoes no acceleration. 该体系不承受加速度作用。
- A way of producing the negative of a number by obtaining its complement. 一种通过求一个数的补码来得到该数的负数的方法。
- All spacemen must be able to bear acceleration. 所有太空人都应能承受加速度。
