第二次世界大战以前日本真空技术的水平是很低的只能做真空管,东京理化研究所仁科芳雄建立了一个160公分的小型迴旋加速器,虽然很小也算作成了,这项工作是和真空技术有关的,直到战争结束迴旋加速器也没有充份发挥其作用,主要是真空技术不够。 战争期间我被征兵了,所以详细情况 Prior to the Second World War Japan’s level of vacuum technology is very low can only do the vacuum tube, Tokyo Institute of Physical and Chemical Ren Kefang established a small 160 cm cyclotron, although small also be done, this work is and vacuum Technology-related cyclotrons did not give full play to their role until the end of the war, mainly due to insufficient vacuum technology. During the war I was conscripted, so the details
