positive peak

The results show that the potential of the oxidation peak of 1,4-DHP ( E_ ( pa)) becomes more positive, and the oxidation process is more difficult with an increase in the electron-attractive ability of the substituent at the C-4 position.

结果表明，1,4-DHP在GC电极上的氧化峰峰电位（EPa）随着C-4取代基的吸电子能力增强而升高，氧化反应越来越难进行。

Methods The physical parameters of blast wave were measured by PCB pressure transducers ( USA) during underwater and air explosions of 200g, 500g and 1000g TNT respectively. Consequently, the propagation speed, peak overpressure value, positive duration and impulse of blast wave were analyzed.

方法分别用200、500和1000g TNT进行水下和空气中爆炸，用美国PCB公司生产的压力传感器测定冲击波物理参数，分析冲击波的传播速度、超压峰值、正向持续时间和冲量。
