你要说米每秒，所以它仅仅是，用来表示频率的，是个频率的标志。
So, this really just means for frequency, it's a frequency label.
人所能使出的最大，速度是10公里每小时，不出意外的话，大概是4米每秒。

如果你在轨道接近，地球，那是8千米每秒，8乘以2平方根，正好是11。
If you are near Earth in orbit, you are eight kilometers per second, and eight times the square root of two 2 is exactly that 11.2.
因为如果单位本应该是米每秒，但你写的是秒每米，你认为这个题目，还有正确的机会吗？
If the units are supposed to come out in meters per second and you get seconds per meter, what do you figure the chances of that problem being right are?
它们被聚集起来投入实验，此时速度大约是5米每秒——仅为空气中分子自由碰撞速度的百分之一。
They are gathered up and injected into the quantum experiment at speeds of around five meters per second - just a hundredth the speed of the molecules flying around in the air.
当物体运动速度达到299792458米每秒时，即达到光在真空中的传播速度时，时间整体停止。
Time stops altogether on reaching the 299, 792, 458 metres per second at which light zaps through a vacuum.
这些被叫做O B速逃星的巨大的恒星在以极高的速度(有时达上百千米每秒)在太空中穿行。
Known as OB runaways, these massive stars tear through space at surprisingly high speed-sometimes hundreds of kilometers per second.
在化学计算中我们很少，用英里每小时，所以我们把它换算为42米每秒，对不起，它是94英里每小时。
We don't usually do our chemistry calculations in miles per hour, so let's switch that to 42 meters per second, so it's — sorry, it's 94 miles per hour.
因为光速是299 792 458米每秒，而中微子的速度是299 798 454米每秒。
Since the speed of light is 299, 792, 458 metres per second, the neutrinos were evidently travelling at 299, 798, 454 metres per second.
如果计算一下，如果你假设，加速度恒定-，那就很好推测了，你会发现，加速度仅仅是，2米每秒的平方。
And if you calculate, if you assume that - the acceleration is constant — it's an easy calculation — it turns out that the acceleration is only two meters per second squared.
所以如果我们稍微想想，我们需要的数值是多少，我们需要一个，大约为10的负30次方米每秒的速度。
So, if we kind of think about the Numbers we would need, we would actually need a velocity that approached something that's about 10 to the negative 30 meters per second.
大部分在阿富汗的室外场景都是在奥兰查沙丘拍摄的。在那里的两天里，摄制组成员需要忍受风速为40 - 60米每秒的大风。
Most of the exterior scenes set in Afghanistan were filmed at Olancha Sand Dunes. There, the crew had to endure two days of 40-60 MPH winds.
例如，一个直径900毫米，600毫米宽本吉涡轮机运行在一个从20米的头立方米米每秒将产生超过260马力左右轴每分钟500转。
For instance, a 900 mm diameter, 600 mm wide Banki turbine running from a head of 20 metres at one cubic metre per second will produce in excess of 260 shaft horsepower at about 500 RPM.
