大学英语核心高频单词
大学英语同样没有全国统一的“单词大全”。常见参照是：四级大纲约 4500 词，六级约 5500—6000 词，考研英语约 5500 词，雅思托福要求更高；各校教材（新视野、全新版、体验英语等）单元词表也不同。
《自然》（20211104出版）一周论文导读
Here we report ab initio-based calculations of compressed silica glasses， showing that the structural changes from low- to high-density amorphous structures occur through a sequence of percolation transitions. When the pressure is increased to 82 GPa， a series of long-range percolating clusters composed of corner- or edge-shared tetrahedra， pentahedra and eventually octahedra emerge at critical pressures and replace the previous ‘phase’ of lower-fold coordinated polyhedra and lower connectivity. This mechanism provides a natural explanation for the well-known mechanical anomaly around 3 GPa， as well as the structural irreversibility beyond 10 GPa， among other features. Some of the amorphous structures that have been discovered mimic those of coesite IV and V crystals reported recently， highlighting the major role of SiO5 pentahedron-based polyamorphs in the densification process of vitreous silica. Our results demonstrate that percolation theory provides a robust framework to understand the nature and pathway of amorphous–amorphous transformations and open a new avenue to predict unravelled amorphous solid states and related liquid phases.

脑机结合！科学家将“人脑”对接到计算机上，缸中之脑会出现吗
人类的大脑或许可以和计算机结合，变得更加强大！你以为这种想法还停留在科幻小说中，殊不知科学家已经实现了！只不过，和你想的有点不一样，科学家不是把芯片移植到人类的大脑中，而是把人类的脑细胞移植到了计算机上。问题在于：二者的结合顺利吗？脑细胞真的能在芯片上运行起来吗？
