The database can assign sequence Numbers to each node so that it knows the position of each node and can compare the document order of two nodes in constant time.

数据库可以为每个节点分配顺序号，这样就知道每个节点的位置，可以在常数时间内比较两个节点的文档顺序。

This function does a good bit of position-munging, but it all boils down to a simple idea: Keep constant the precise distance between the mouse cursor and the target object.

该函数做很多位置整理(position - munging)工作，但都可归结为一个简单的思想：不断保存鼠标光标与目标对象之间的精确的距离。

And since we are not expecting the mass of the particle to change, what we really are saying is the uncertainty in its velocity times the uncertainty in its position is greater than the ratio of the Planck constant divided by 2 pi.

因为我们不期望,粒子质量发生变化，我们说的是,它速度的不确定度,乘以它位置的不确定度,比普朗克常量,除以2除以圆周率要大。
