And, the way we can get it, so, it's called usually V, so, V here stands for velocity more than for vector. And, you just get it by taking the derivative of a position vector with respect to time.
根据它的原理,我们通常用v表示,这里的V更代表速率而不是矢量,你能通过,对一个关于时间的位置向量求导得到它。
v0 And there is an angle between ; the position vector and v zero; 0 I call that phi zero.
在方位向量和,之间,有一个夹角;,我们叫它φ
For example, the code above will record a tile with a filename like v=w2.80&hl=en&x=228&y=4&zoom=15&s=Gal to be at position 0,4 in the (column,row) hash.
例如,以上的代码将把文件名为 v=w2.80&hl=en&x=228&y=4&zoom=15&s=Gal 的图像块记录到 (column,row) 散列中的位置 0,4 中。
