In this case, the Ares I-X took a ride on one of two crawlers built to carry around the Saturn V rockets that sent astronauts to the moon.

这一次，战神一号X型乘坐的“战车”就是那时的两辆履带车之一，当年它运送的土星v火箭把宇航员送上了月球。

fullprof A complex variable has real and imaginary parts written in the form b(x) = n(x) + iv(x) for two real-valued functions n(x) and v(x)

单复变量包含实数和虚数两部分，针对两个实值函数n(x) 和 v(x)的表达式为：b(x) = n(x) + iv(x)。

Now what I want to find,actually, V is what are these two vectors, let's call them U and V, that correspond to moving a bit in the x direction or in the y direction?

现在我实际上想知道的是，这两个向量是什么，我们称它们为，U和，两者对应的是x方向和y方向一点位移？

As long as we understand that, we can do this cancellation and this says on the left-hand side the change in the quantity v square over 2 is a times the change in the quantity x.

只要我们明白这一点,我们就可以这样做简化,在等号左边,v^/2的变化量,为a乘以x的变化量
