Between 2000 and 2001, in contrast, the migrationrate fell from over 15% to under 14%.
与此形成鲜明对比的是2000年到2001年。人口流动率从15%以上降至不到14%。

In the same structural model, hydrocarbon migrationrate within interim opening fractures is faster than that of permanent ones.
在相同地层结构模型中，间歇性开启断裂中的油气运移速度较永久性开启断裂快；

Hall coefficient depends on electronic concentration and the relative values of empty hole concentrations and their migrationrate in the semiconductor.
