So, if we think about this z bonding axis between the two carbon atoms, we can picture overlap of those s p hybrid orbitals, and then we can also picture bonding to hydrogen. 如果我们考虑,两个碳原子之间的z成键轴，我们可以画出sp杂化轨道的交叠，我们也可以画出和氢原子的成键。 - 2
So it's along the bond axis and it's between a carbon s p 2 hybrid, and then the hydrogen is just a 1 s orbital that we're combining here. 所以它是沿着键轴方向的,而且这里是一个碳sp2杂化轨道，和一个氢的1s轨道的结合,在这里我们可以合并他们。 - 3
No significant differences were found in the heart rate, QRS intervals, Q T intervals, sinus bradycardia, sinus tachycardia and left axis deviation between exposed and control groups ( P >0 05). 其余心率、QRS间期、Q-T间期的数值以及窦性心动过缓、窦性心动过速和心电轴左偏等发生率，两组之间均无差异（P＞0．05）。
