xda的翻译

XdA So, I said we had to compute the double integral of x dA over this region here, which is a disk of radius one, centered at, this point is.

我们需要计算二重积分，在这个区域上，区域是一个半径为1的圆盘，中心在点。

So, switching the area, moving the area to the other side, I'll get double integral of xdA is the area of origin times the x coordinate of the center of mass.

那么，改变一下区域，把这块移到另一侧，我们得到对xdA的双重积分，是原点那的圆面积乘质心的x的坐标。

For example, you can't buy the Storage Optimization Feature Pack which provides compression services for tables, temporary tables, indexes, the XML XDA area, and more.

例如，您不能购买为表、临时表、索引和XML XDA等提供压缩服务的Storage Optimization Feature Pack。
