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？
Texture coordinates are named (s, t) in order to distinguish them from the (x, y) used for vertex positions (in literature, (u, v) is commonly used instead).
将纹理坐标命名为(s,t)是为了与用于表示顶点位置的(x,y)区分开来(从文字角度来讲，(u,v)更为常用)。
OK, so this one means we keep y constant, and partial f over partial u with v held constant, similarly.
这个的意思是，保持y恒定，而这个的意思是，保持v恒定。
If x and y were functions of t instead of being functions of u and v then it would be the same thing.
如果x，y是t的函数，而不是u，v的函数,那么还是一样的。
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。

A striking feature of the allelic patterns detected by these probes was that cells with the same AH had identical Y, X and V alleles(i. e, the alleles were haplotypic).
这些等位基因的一个显著特点是：相同的AH具有相同的Y、X、V等位基因型（即呈单体型性质）。
