该装置是借助于模型上方的高气压来紧实型砂的。与普通爆炸紧实工艺相比,这种高气压主要是通过高压电流的电弧放电而产生的,其时有液态和(或)固态的并且正在蒸发和
The device is by means of high pressure above the model to compact the sand. Compared with the normal explosion compact process, this high pressure is mainly generated by the arc discharge of high-voltage current, when liquid and / or solid and is being evaporated and
