1·So we have h, then we can draw our bond as a line.
那么我们有氢，可以把我们的键画成一条线。
2·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。
3·Radial Solutions, Hydrogen Wave Functions, H Spectrum.
辐射式方程的解，氢原子波函数，氢光谱。
4·In their elementary composition, the enzymes show the usual proportion of c, h, n, and s found in proteins.
从元素组成来看，酶显示出与通常蛋白质一样的碳，氢，氮及硫的元素比例。
5·Studies of the C and H isotopic composition of natural gases of continental origin will provide valuable information on the prospecting and development of natural gases of different genetic types.
通过对我国陆相成因天然气碳、氢同位素研究，探讨其同位素组成特征及其意义，从而为各种成因类型天然气的勘探开发提供了有益的信息。
