在b1-b4中,由于新的共价键的形成,二面角DN1-C2-N3-C4, DN1-C2-N3-C4, DC2-N3-C4-C5 和 DC4-C5-N1-C2分别从接近于0度变化至19.9,-22.6,-21.2和1.2度。而在b5-b8中,共价键C2-H,C4-H或者C5-H被破坏,导致键角N1-C2-N3,N1-C2-N3,N3-C4-C5 和C4-C5-N1分别从109.0,109.0,107.1和107.2变化到了103.1,103.1°,101.7°和101.8°。

抛砖引玉!

Because of the formation of new covalent bond, the diherdral angles of DN1-C2-N3-C4, DN1-C2-N3-C4, DC2-N3-C4-C5 and DC4-C5-N1-C2 varied from 0 degree to 19.9,-22.6,-21.2 and 1.2 degree, respectively, as seen in b1-b4.However,due to the covalent bonds of C2-H,C4-H or C5-H have been destroyed, which resulted in bond angles of N1-C2-N3,N1-C2-N3,N3-C4-C5 and C4-C5-N1 varied from 109.0,109.0,107.1 and 107.2 to 103.1,103.1°,101.7° and 101.8°, respectively, as seen in b5-b8.

没仔细检查,楼主可以在仔细看看!

because the formation of new covalent bond in b1-b4, the dihedral angle DN1-C2-N3-C4, DN1-C2-N3-C4, DC2-N3-C4-C5 and DC4-C5-N1-C2 change from nearly 0 degree to 19.9,-22.6,-21.2 and 1.2 degree respectively. nevertheless, in b5-b8, the covalent bonds of C2-H,C4-H or C5-H are distroyed, which result in   the bond angles varying from 109.0,109.0,107.1and107.2 to 103.1,103.1°,101.7°and101.8°,respectively。
修改版 第一次帮忙翻译 不好请见谅啊
