本文介绍了中国专利产品ZHL - 75阶壁锥形除砂器的结构特征及原理。
We report the Young's modulus of a series single-wall carbon nanotubes (armchair type and zigzag type) and BN zigzag type nanotubes on the basis of ab initio theory.基于第一性原理计算了一系列单壁碳纳米管(椅型、锯齿型)和氮化硼锯齿型纳米管的杨氏模量。
Control an orb ball along the zigzag path and don't hit the wall.控件一起锯齿形路径的天体球不打墙。
