"What is life but a motion of the limbs?
除了四肢的运动,生命为何物?
This spring is getting squashed on either side, and it'll squash by certain amount x, that depends on your mass, and that x will be turned into a motion of a needle and that'll read your mass.
这个弹簧两边都会受到压缩,压缩量为 x,它由你的质量决定,x 会转换成指针的运动,你从而可以读数
The Turkish Parliament passed a motion calling for a complete review of all political,economic and military ties with Israel.
VOA: standard.2010.06.03
That would that would give rise to a perpetual motion machine, breaking of the second law. It can't happen.
否则就会使,得永动机出现,打破第二定律那是不可能的。
"This was a possession of marijuana case, and we had filed a motion to suppress evidence,"
VOA: standard.2009.05.22
What he did was took de Broglie motion of the electron as a wave and developed a wave equation for such matter waves.
他所做的就是,用电子的德布罗意运动,作为波并且对于那种物质波,给出波动方程。
The members of Somaliland's Lower House of Parliament introduced a motion to impeach the president this weekend, which if successfully passed by the majority would require a two-thirds vote in the Upper House of Parliament to finish the impeachment.
VOA: standard.2009.09.07
But luckily for us, there's a classical equation of motion that will, in fact, describe how the electron and nucleus change position or change their radius as a function of time.
但幸运的是,有一个,经典方程描述了电子和核子,位置或者它们直接的距离是,如何随时间变化的。
Keep them up. Wave them in the air with a bit of motion.
先别放下手,再举一小会
All matter contains within it something like a "potency of life"; that's Milton's phrase. It has a capacity for action, actually a capacity for motion, and, just as books can take on a life of their own in Areopagitica, so all matter for later Milton.
所有物质都更包含一种类似“生命的潜质“的东西;,这是弥尔顿的原话,所有物质都有行动的可能,运动的可能,正如《论出版自由》中书籍可以有自己的,生命一样,晚年的弥尔顿相信一切物质都是这样。
I get to the end of the loop, and I actually do a little bit of wasted motion there. And the little bit of wasted motion is, I take the value at i, store it away temporarily, take the value where min index is pointing to, put it back in there, and then swap it around.
我走到了循环的末尾,事实上我做了多余的动作了,有点多余的是我把i的值,临时保存起来了,看看MinIndex指向的值,放回到哪里,然后再交换。
One way to say it is, every body will continue to remain in a state of rest or uniform motion in a straight line.
另外一种说法是,任何物体都会继续保持静止,或匀速直线运动的状态
We're describing the motion of a particle in a circle.
我们描述了圆周上一个点的运动
So what I'm saying here is we are specializing to a limited class of motion where the particle has a definite acceleration, a.
我在这里想说的是,我们正在专门讨论一类问题,这些问题中,质点都有一个确定的加速度a
And it turns out that the Schrodinger equation is an equation of motion in which you're describing a particle by describing it as a wave.
结果是薛定谔方程,用描述粒子波动性的方式,来描述这个粒子。
People to this day are looking for a theory of everything. And there is something very appealing about the notion that the rules that govern the motion of heavenly bodies might be applicable down at atomic dimensions.
现在人们总想寻求一些,可以阐明一切的理论,而这里正好有一些,可以吸引这种想法的东西,即支配天体运动的规则,可能对原子的尺寸也是适用的。
So, time is measured as a parameter along the motion of the particle.
这样,时间就被记为质点运动的一个参数
That's a problem of projectile motion.
这是抛体运动的问题
For example, suppose you use vertical motion and you use y instead of x; and a would be g or -g; that's a particle falling down under the affect of gravity.
例如,假设在竖直运动中,你用 y 来代替 x,那么 a 就是 g 或者 -g,这就是一个受重力作用下落的质点
