二普通平开窗的五金配件平开窗的基本配件之一是合页。由于合页的单向开启性质,合页总是安装在开启方向,即内开窗合页安装在室内,外开窗的合页安装在室外。为了不让合页影响窗的密封,金属窗的合页通常焊接在窗型材的外面。外开窗的锁是一种旋转的卡式锁,把手通常与锁相结合。普通内开窗的锁则可以是简易的插销。插销的缺点是没有旋转的卡式锁的压紧功能。内开窗的把手是独立的,与其它部件不发生关系。限位器是外开窗必备的部件,防止风将窗扇吹动并产生碰撞。

一旦达成协议,两岸经济将进一步整合。据介绍,此前ECFA早收清单的95%已降至零关税,两岸透过经合会下的货品贸易分组,已进行新一回合的降税谈判。对于降税清单,双方初步拟定:第一类是关税直接降至零;第二类是分阶段降至零;第三类是分阶段降税,但Zui终不降至零。双方将在此架构下,进一步谈判彼此的开放项目与幅度。另据悉,在1月31日举行的大陆台商春节联谊活动上,台湾当局领导人马英九表示,在539项ECFA早收货品清单中,有59项、高达94.5%的产品自今年起销往大陆享有零关税待遇,明年起则早收产品全都是零关税。
