近日，东南大学博士生导师陈洪兵教授在小红书上说：自从博士扩招，博士由考试入学改为考核入学后，博士生源质量明显下降，博士们根本不读书，水平比硕士还差。所以近年来他都是劝退想读他的博士的考生们，先想清楚再读博，宁缺毋滥。混个博士学位一点用都没有，纯粹浪费教育资源！
。夫子对此有专业解读
五奶奶说，那时候闻讯赶来的亲戚，少说都有20个，大伙折腾了一上午把幸存的骡子弄上来。亲戚们还把自家骡子牵过来，一共八头骡子把一地麦秆驼回了五奶奶家。打那之后，她再没种那块地。她怕再闯祸，也不好意思再麻烦人。
Mesh routers, or mesh Wi-Fi systems, use multiple devices (or nodes) across your home to create a larger home network. Essentially, you have multiple routers around your home with these systems, and that will hopefully provide the best coverage possible. Wi-Fi extenders, on the other hand, are usually just one device that extends your existing Wi-Fi signal, and they often require you to switch networks when connecting. Wi-Fi extenders are more affordable, though, and are great if you’re traveling or need a Wi-Fi signal in harder-to-reach areas. However, a mesh router can offer a better long-term solution to upgrade your entire home’s Wi-Fi.
