sash window-
One night I woke up to find my sash window open and the tall figure standing4 on the balcony , looking out across the town .
一天晚上，我醒来看到推拉窗开着，阳台上有个高高的黑影，正看着整个镇子。

The sash window in the room I stayed in would never close fully and condensation used to build up on my full length mirror .
我房间的上下推拉窗总关不严，所以夜里我的大穿衣镜上会凝结水汽，第二天早上，就会在镜子下方看到两个小手印。

The flow rate of suspend sash window has almost the same quantity with that of sash window under the same ventilation area .
在通风面积基本相同条件下，利用悬开窗通风时的通风量与利用推拉窗通风时的通风量相差不大。

Sash-cord ( cord with a weight at one end running over a pulley and attached to a sash , allowing the window to be kept open in any position )
吊窗绳（一端有坠，另一端固着于垂直拉窗的窗框，中间有滑轮，可使窗户停留在任何开启位置）。
