在最稳定几何构型基础上，基于自然键轨道理论，分析了稳定结构的成键情况和吡唑环上的共轭性；用静电势图分析了吡唑化合物的反应性；理论估算了9种化合物的标准气态生成热和Bader密度；最后采用VLW方程计算了这些化合物的爆速、爆压。

For 9 pyrazole compounds, their geometry and electronic structures were analyzed by means of natural bond orbital theory; their reactivity was analyzed by electrostatic potential distributions, heats of formation and Bader density were also calculated. After that, detonation velocities and Chapman-Jouguet pressures of these compounds were given by means of VLW equation.
