Graphene produces a working 3D holographic display

Since "Help me, Obi Wan, you're my only hope" hit the big screens in 1977's "Star Wars," we've been dreaming of a full-3D holographic display. Mastering the technology isn't easy, though. We've seen multiple attempts that approximate a 3D display, like a 2D image visible from all directions, but …

硬拉容易导致腰伤,你还在错误的训练硬拉吗?

错误的硬拉训练及其容易造成腰伤,不正确的硬拉为什么会导致腰伤,你想过吗?<p>什么是硬拉,如果你还不太明白,你需要查阅资料区分一下屈腿硬拉和直腿硬拉。重要提示:在训练硬拉之前请务必慎重,从小重量开始,做到心中有数,切勿盲目训练!硬拉训练注意事项一般都会有类似描述:<b>要控制住重量,动作平稳,提铃和还原过程腰要绷紧,不得含胸弓腰,提拉杠铃至极限时不得腰背后仰,否则容易造成腰椎损伤。</b><p>上面的描述有几个要点,圈出来要考!控制住重量,这旨在提示重量在可控范围,大重量虽然能够突破训练强度,但大重量同样危险,什么是大重量?这并不是一个确切的重量,对别人而言20KG的哑铃弯举都不属于大重量,但对你来说它就是!训练过程中 …
