在回家的路上，穆兰显得格外的安静，我不时地从后视镜中看她，她坐在后座上，眼睛盯着窗外。
2·Easy View does not block rear visibility and does not need to be positioned directly over a child. The shallow convex shape offers the largest, clearest reflection of any back seat mirror.
后座反射镜，视野宽阔，不会阻碍后视镜的能见度，也不需将孩子直接对着后视镜，凸透镜最大最清晰地映射出所有后座镜子的情况。
3·In a beam transmission system of a CO2 laser, the reflection mirror can be used as back-view mirror or foldable reflection mirror in the laser cavity, while as a light bender outside the cavity.
在CO2激光器的光束传输系统中，反射镜在激光管腔内被用作尾镜和折叠式反射镜，而在腔外则充当了弯光器的角色。
