新华社兰州6月4日电 题：在西部，有一群"追光"的青年科学家 新华社记者白丽萍、吕京笏 发挥专业优势，积极服务国家防灾减灾和地方生态环境修复；探索前沿科学技术，推动高质量发展；迎 难而上，矢志攻克世界性难题……有这样一群"追光"的青年科学家，他们扎根西部，用实际行动贡献力 量。 2012年冬天，在美留学的谢文刚，给中国工程院院士、兰州大学草地农业科技学院教授南志标发了一封 求职邮件。第二天，他就收到了南志标的回信："我们努力给年轻人搭建一流的学术平台，欢迎你来到 兰大，来到西部。"谢文刚深受感动，老家是四川的他决定到兰州大学这个"彼此需要的地方"。 青藏高原是我国重要生态安全屏障，需要优良牧草品种用于生态修复和草地改良。入职后，谢文刚与团 队负责人王彦荣教授深入交流，围绕青藏高原育种，将高产抗病的青藏高原优良牧草老芒麦和垂穗披碱 草作为育种目标。 10余年来，谢文刚在甘肃、四川、青海建立高寒牧草育种平台，并在挖掘牧草基因和新品种选育领域取 得系列创新成果。他选育的两个"兰育"系列老芒麦新品系正在开展大范围的生产试验。他还积极与领域 内企业开展产学研结合，推动青藏高原草产业发展。 攻克"卡脖子"难题，折射着青年 ...

芮新龙介绍，农场从端午节当天开始插秧，全部采用机插秧方式，每天出动2—4台插秧机，每台 插秧机平均每天作业四五十亩，预计6月20日将完成全部插秧工作。 农机是夏收夏种的"主角"，不仅为抢抓农时赢得关键时间，更让夏收损耗降到最低。目前我市稻麦 生产耕种收综合机械化水平达98%以上，全市主要粮食生产基本实现全程机械化。 "今年公司种了约2000亩小麦，品种主要为扬麦33、扬麦45和扬辐麦15，今天下午开始收割，预计 3天左右全部收完。"南京金庄智慧农业科技有限公司技术总监马银飞告诉记者，他们种植的小麦和普通 农户不一样，收获后不是直接销售或加工，收完的小麦要立即烘干熏蒸和精选，然后包装储存，作为下 一季小麦种植的种子供给六合及周边农户。 "三夏"时节，夏收连着夏种，农人们在收麦的同时也忙着夏种插秧。当天，在高淳区桠溪街道新龙 家庭农场里，两台插秧机宛如"撒欢"的"铁牛"穿梭在稻田内。农场负责人芮新龙指挥工作人员将一盘盘 青翠的秧苗有序摆放在机台上，农机手娴熟地驾驶着插秧机开展作业。随着插秧机向前行进，一株株秧 苗从苗盘上依次滑落、插入田中，所过之处一行行秧苗整齐挺立，宛如为稻田穿上嫩绿的"新装"。 记者昨天从市农 ...

普渡大学的研究人员正专注于研究 TSV——它们在保持足够坚固可靠的情况下，可以做到多小。 TSV 是极细的铜线，直径通常为 5 微米（约为人类头发丝厚度的十分之一）。将这些铜线排列在 堆叠的硅芯片之间，可以实现芯片间极快的通信速度，从而实现极高的带宽和快速的处理速度。但 这需要付出代价。 "先进3D封装的最大挑战之一是散热问题，"机械工程 博士生吕书航说道。"高密度材料如此紧密 地排列在一起，产生的热量比传统的2D芯片更多。物理材料开始变形和破裂，从而影响性能和可 靠性。" 换句话说，仅仅缩小硅通孔尺寸并增加数量并不能提高芯片速度。物理材料（导线的铜和芯片的 硅）在相互接触、升温并开始相互推拉时会遇到问题。随着导线尺寸的减小，问题变得更加棘手 ——发热问题更加严重，而且导线的弹性也会随着收缩而发生变化。 如果您希望可以时常见面，欢迎标星收藏哦~ 来源：内容来自Source：编译自purdue 。 随着计算机处理器体积越来越小、性能越来越强，半导体工程师们正面临芯片运行速度的物理极 限。一种策略是将芯片进行三维堆叠，并使用被称为硅通孔 (TSV) 的微型导线作为垂直连接器。 Lyu 对 TSV 和硅之间的相互作 ...
