GAA100/580闪光焊机的焊接过程与电气控制

【Objective】 To study the characteristic of flash visual evoked potentials(FVEP) on term infant and premature infant within 6 months old.

【目的】研究足月儿和早产儿的闪光视觉诱发电位(flash visual evoked potentials,FVEP)特点及临床应用。

To obtain the radiation property of typical flash pyrotechnics, the typical composition scale was selected through measuring radiation intensity of visible light and infrared.

研究获得典型闪光烟火剂的辐射规律 。
