三百八十六章：后天送你们礼物

“好的老师。”蔡晨宁教授旁边的一位学生站了起来。
这是一位看起来颇为成熟的男性，他的皮肤有些黝黑，双手似乎还残留着油污长期浸泡出的黑渍，看起来更像一名工人。
他是蔡晨宁教授带的唯一一名弟子，正在攻读博士学位的谢彤涛。
他今年二十八岁，博士已经是最后一年，在sci上，发表过三篇专业论文。之前拿到那颗螺母，就是谢彤涛负责技术攻关。
不同于法学或是工商管理之类的博士头衔，机械工程类博士，除了专业知识要过硬外，动手能力也要非常强悍。
谢彤涛并未先接过螺母与螺丝，而是给自己带了一双防静电手套后，才接过这两件，代表了工业领域中最高难度之一的金属零件。
或许大家都有过类似经历，在拧一根螺丝时候，刚开始似乎很难将螺丝对准螺母。越是小巧到螺丝越是如此，那是因为螺纹与螺纹之间的间距太小，很难找准正确的镶入位置。
“咔嗒～”
多媒体中心与直播间内，再次传来清晰的金属接触声音。
“没有用的，这颗螺母我们从压铸胚件，到一体削切成型。再到伟大的工业母机，进行雕刻螺纹，和百级洁净车间m..内，用离子体气相沉积进行纳米级金刚石镀膜，一共用时十天。”
“这就是工业，这就是最尖端的技术。”
“你们不可能出……”
“等等～这怎么可能？”小林井原本得意的声音，顷刻间猛地提高了八个音度。连瞳孔似乎都扩大了八倍，牢牢看住了谢彤涛手中的那个螺母。
“咝～咝～咝～”
视频画面中，那颗螺丝似乎找到组织，又似乎辗转千百遍，终于成功找对了洞口。
那颗螺丝再也不是之前的漫无目的乱动，而是笔直地，非常有节奏地，随着手指旋转，一圈圈朝着螺母内前进。
五圈～十圈～二十圈～
咝咝声，变成了非常有节奏感的沙沙声。
大约两分钟后，螺丝全部拧入螺母内。谢彤涛将这颗连接好的螺丝与螺母丢给小林井，让他们检测一下，到底有没有拧紧？
接过这件东西，小林井在仔细检查过程中，脸色越来越糟糕。
完美无缺！
螺丝与螺母牢牢镶嵌在一起，浑然一体。
现场寂静了五秒钟，随后轰一声爆了，全体学生们站起来鼓掌。
“啊！”
“成功了，你们看见没有，螺丝被成功拧进去了。”
“哈哈～我就猜是教授年龄大，眼神不好使的原因。你们看，谢博士一出手，不到十秒就成功了。”
“那个小林井教授笑死哥哥了，还扯什么伟大的工业技术，要十天。大家看，巨兽重工的叶总多霸气，昨晚校长请他吃饭，他直接让蔡教授第二天去取螺丝。”
“真的假的，校长请叶总吃饭，你们怎么知道？”
“因为我在场啊，当时叶总看我们这十来位学生太辛苦，把我们也喊过去吃饭。结果饭桌上，蔡教授拿出那颗螺母时，叶看都不看就踹兜里，说明天搞定。”
“而且叶总还要来我们学校读研究生，所以这颗螺丝是我们学校学生做出来的，比日理工找外援厉害多了。”
