Its working process is: anticipate on the artificial- automatic position- automatic clamp- automatic milling, after milling unclamped the work piece automatically and taken down the workpiece by the operator.

工件以其主轴孔定位，定位心轴置于圆盘工作台上，圆盘工作台主轴呈卧式安置；它的工作过程是：人工上料——自动定位——自动夹紧——自动铣削，铣毕自动松开工件后由操作者取下。

The closed-cell aluminum foam was fabricated by direct foaming in melt. Through sampling aluminum foam in different stages the cross-section of them were observed and analyzed. It was explained how TiH_2 was decomposed after entered into the melt, how initial bubbles were formed and what was the state that generated bubbles and undecomposed TiH_2 lay in.
