中国天眼一周岁:为梦想燃烧生命的天眼之父南仁东

2017-09-26 14:38:51   

有人告诉他,贵州的喀斯特洼地多,能选出性价比最高的“天眼”台址,南仁东跳上了从北京到贵州的火车。绿皮火车咣当咣当开了近50个小时,一趟一趟坐着,车轮不觉间滚过了10年。

1994年到2005年,南仁东走遍了贵州大山里的上百个窝凼。乱石密布的喀斯特石山里,不少地方连路都没有,只能从石头缝间的灌木丛中,深一脚、浅一脚地挪过去。

时任贵州平塘县副县长的王佐培,负责联络望远镜选址,第一次见到这个“天文学家”,诧异他太能吃苦。

七八十度的陡坡,人就像挂在山腰间,要是抓不住石头和树枝,一不留神就摔下去了。王佐培说:“他的眼睛里充满兴奋,像发现了新大陆。”

1998年夏天,南仁东下窝凼时,偏偏怕什么来什么,瓢泼大雨从天而降。因为亲眼见过窝凼里的泥石流,山洪裹着砂石,连人带树都能一起冲走。南仁东往嘴里塞了救心丸,连滚带爬回到垭口。

“天眼”之艰,不只有选址。

这是一个涉及领域极其宽泛的大科学工程,天文学、力学、机械、结构、电子学、测量与控制、岩土……从纸面设计到建造运行,有着十万八千里的距离。

“天眼”之难,还有工程预算。

有那么几年时间,南仁东成了一名“推销员”,大会小会、中国外国,逢人就推销“天眼”项目。

“天眼”成了南仁东倾注心血的孩子。

他不再有时间打牌、唱歌,甚至东北人的“唠嗑”也扔了。他说话越来越开门见山,没事找他“唠嗑”的人,片刻就会被打发走。

审核“天眼”方案时,不懂岩土工程的南仁东,用了1个月时间埋头学习,对每一张图纸都仔细审核、反复计算。

即使到了70岁,他还在往工地上跑。中国电子科技集团公司第五十四研究所的邢成辉,曾在一个闷热的夏日午后撞见南仁东。为了一个地铆项目的误差,南仁东放下筷子就跑去工地,生怕技术人员的测量出了问题。
