So it looks a lot less messy if we just draw our Lewis structure like this for h c n, where we have h bonded to c triple bonded to n, and then a lone pair on the nitrogen there.
这看起来整洁了不少,如果我们把氰化氢的路易斯结构画成这样的话，这样我们就有氢与碳之间的单键和碳与氮之间三键，然后还有一对孤对电子在氮这里。
We calculated the one - loop correction of W - N theory with unitary approach and H - N theory with covariant approach, then discussed the difference between the two approaches.
本文运用协变方法和么正方法，分别给出了W-N理论和H-N理论量子宇宙波函数的单圈修正；并且讨论两种算法的差异性及矢量-张量引力理论的可行性。
Based on the characteristics that in coal bed gas exist rich benzene and poor N-hexane, the authors propose two indicators as"Benzene lndex"(B)and"N-hexane lndex"(H)to distinguish the coal bed gas.
根据煤层气体具有富苯和贫正己烷的特征，提出了“苯指数”（B）和“正己烷指数”（H）两项判别煤层气的指标。
