By the time he passed four thousand feet he had reached terminal velocity, the wind was a solid beating wall of sound against which he could move no faster.

他穿越四千英尺的高度时，已经达到极速，呼啸着的海风就像一堵坚实的墙，拦在前面，使他无法以更快的速度前进。

With analysis of forces on particle and calculation of terminal velocities, terminal velocity models are selected, and then Pulse jamming settlement theory was discussed.

在颗粒受力分析及沉降末速计算基础上，首先选取了沉降速度模型，进而对脉动干扰沉降理论做了初步探讨。

The falling object, after traveling a certain distance through the air reaches a final speed, or "terminal velocity," because the object's friction with the air slows the fall.

物体在下落一定距离后由于空气阻力都会达到一个终极速度。

物体在下落一定距离后由于空气阻力都会达到一个终极速度。

If you know what m is, the mass of an object, the radius, and you know the values for C1 or C2 of that medium in which you move it, then you can calculate what the terminal velocity is.

如果你知道M是什么，是物体的质量，半径，知道C1值或者，媒介的C2值，然后你，就能算出终极速度。
