早上8点，太阳还未升起，阿勒泰地区气温降至零下40摄氏度。 套上防寒衣物，国防科技大学气象海洋学院副教授刘西川带领团队直奔山口。 "一定要注意安全！"出发前，当地气象局工作人员再三叮嘱。 此次外场观测试验的对象是风吹雪。仪器架在风口，大风把地上厚厚的积雪吹到天上，漫天飞舞，风像刀子一样，刮得脸生疼。顾不上手脚冻透，大家把 握时机，轮流观测。两周后，团队如愿拿到连续、完整的观测试验数据。 走自主创新的"险途"—— "我们必须研制自己的仪器" 长期以来，高端气象观测仪器依赖进口，不仅成本高昂，更在核心技术与数据安全上受制于人。 "我们必须研制自己的仪器。"从本科到博士都专攻大气探测的刘西川，立志要闯出一条气象仪器自主研发的道路。 经过无数个日夜的攻关，团队创新性提出单帧多曝光成像测量方法和多目立体视觉成像方法。与传统翻斗式雨量筒只能记录降雨总量不同，它们就像"火 眼金睛"，能精确捕捉到雨雪的瞬态微物理特征，清晰"看"到每一个雨滴、每一朵雪花的立体结构和运动轨迹，这些恰恰是理解降水发生发展机制的核心 所在。 作为一种全新的技术体制，团队自主研制的降水瞬态微物理特征测量仪被纳入最新版世界气象组织《气象仪器与观测方法指 ...

记者丨费心懿 编辑丨张伟贤 在锂电池的结构中，正极与负极之间维持着一种危险的平衡。为了防止两极直接接触造成短路，它们必须被一层布满微孔的高分子薄膜物理隔 开。这层膜，就是隔膜。 隔膜的厚度通常以微米计量，7微米到9微米。但恩捷股份（002812.SZ）创始人，董事长Paul Xiaoming Lee（李晓明）和副董事长兼总经理李 晓华这对"李氏兄弟"的目标是将这个间隙做得更薄。 这种近乎透明的薄膜，决定了电池的安全性与能量密度，也决定着一个家族在财富榜上的地位。 12月26日，锂电产业链再掀小高潮，恩捷股份盘中一度触及涨停。截至收盘，恩捷股份报56.71元/股，涨幅9.10%，市值557亿元。 年初至今， 该股涨幅超过70%。 但如果将时间线拉长， 恩捷股份股价较巅峰时期已跌去八成，市值蒸发超过2500亿元。 技术海归的商业嗅觉 李氏兄弟二人的技术基因为后来的创业埋下伏笔。他们所选的第一个赛道是卷烟包装BOPP薄膜。在云南这个烟草大省，这几乎是一门躺着赚 钱的生意。 但李晓明很快意识到，烟草行业的护城河来自特许经营的红利，而非技术的迭代。 2010年，特斯拉正处于濒临破产后的喘息期，而全球新能源汽车产业尚处萌 ...
