1·Migration is usually defined as "permanent or semipermanent change of residence".
移民通常被定义为“永久或半永久的居住变化”。
2·In machine construction, couplings are used to effect a semipermanent connection between adjacent rotating shafts.
机械构件中，联轴器可以用来实现相邻两根旋转轴的半永久性联接。
3·One current solution is, if I'm going to apply a semipermanent transform to a view (and not merely waggle it temporarily somehow), to remove all constraints affecting it.
当前的一个解决方案是，如果我打算申请一个半永久性变换到一个视图(而不是仅仅来回动它暂时以某种方式)，以消除影响这一切的约束。
