And, if you ever get confused, the way to remember these is that you know energy is the integral of a force moving through a distance.
如果你感到很困惑的话，可以这么来记,能量是在沿力的方向进行路径积分。
-
Energy is the integral of force moving through a distance.
能量是在沿力的方向,进行路径积分。
-
q2 So q2, the heat in this way is negative.
所以沿这个方向的，是负的。
-
It's good to have a vector pointing in the radial direction of length one.
所以引入这么一个模长为 1,方向沿圆心向外辐射的矢量作用很大
-
The nucleotide has a directionality, there's an up and a down to it and it's going to turn out the chain that's formed by polymerizing these has a directionality as well and that's important in defining the structure.
核苷酸有方向性,有上端和下端,核苷酸长链,是由核苷酸沿一个特定方向聚合而成的,这在定义结构时很重要
-
And what here is just a graph of the 1 s wave function going across some radius defined this way, and you can see that the probability - well, this is the wave function, so we would have to square it and think about the probability.
这里是,1s波函数,沿这个方向的图，你们可以看到概率,这是波函数，所以我们可以把它平方,并想成是概率。
-
er is a vector at each point of length one pointing radially away from the center.
r 是一个模长恒为 1 的矢量,方向沿半径向外
-
Car is traveling with some initial speed v0 in the horizontal direction.
车以 v0 的初速度沿水平方向开出
