Web最后,回到原始问题,如果认为g代表重力加速度,严格说是地表自由落体运动的加速度,则g是9.8 m/s²。. 如果说g是地表物体受到的地球引力与其质量的比值,则 说它等于9.8 N/kg的前提是——“牛顿”这个单位,是通过牛顿第二定律这一物理定律,从质量和 ... WebFurthermore, considering the N 1s binding energy of C 59 N, it is possible that binding energies at the higher end of this range are incorrectly assigned to pyrrolic N, and are actually graphitic N. If this were the case, however, the atomic origin of the next higher binding energy component around 401.5 eV would have to be rethought (notably ...
WebFurthermore, graphitic-N increased 30–40% when anthracene was added to the original precursors. From the results of electrochemical measurements, the current density was proportional to the content of graphitic-N, while a higher percentage of amino-N shifted the ORR onset potential to more positive values. N-doped carbon with the highest ...
