1、'm going to draw it in red. OK, so that's a unit vector that goes along the curve, and then the actual velocity is going to be proportional to that.───现在画成红色，这就是，沿曲线的单位速度向量，实际中的速度向量与它成比例的。
2、given by a vector field that points toward the origin and whose magnitude is inversely proportional to the square of a distance from the origin.───由一个指向原点的向量场给出，并且此向量场的大小，与其到原点的距离的平方成反比。
3、to answer that we have an easy observation, which is that the vector from Q0 to Q of t is proportional to the vector from Q0 to Q1.───为了回答这个问题，我们观察可以知道，由Q0指向Q的那个向量,和由Q0指向Q1的向量成比例。
