The shutter speed of the imaging method is fast enough that scans might one day be taken of molecules caught in the middle of a chemical reaction. 他们的造影方法因为「门速度」快,未来有可能捕捉得到化学反应进行时的分子影像。
It was found and verified that the chemical reaction of condensed phase excited by pulsed laser consists of three stages, photochemical reaction, slow chemical reaction and fast accelerating chemical reaction, and the reactivity photoacoustic spectrum has a typical double peak. 研究发现并证实了脉冲激光激发下凝聚相的化学反应由光激发化学反应、慢速化学反应和快速加速的化学反应等三个阶段构成,反应性光声谱呈现出明显的双峰。

However, under certain conditions when the relevant time scale is extremely small such as in the cases of thermo-explosion, nuclear fusion, very fast chemical reaction and the interaction of high power laser with materials, some modifications should be made for the Fourier's law. 但对于热爆炸,热核聚变,快速化学反应,强激光与物质相互作用这样一些时间尺度极短(与从非平衡态达到局部平衡态的时间相比)的情形,需对Fourier定律进行修正。
Then the state equations of the fast modes and the reduced chemical kinetics model are obtained. A typical mixed combustion reaction system of CO-CH_4-Air is calculated, and the results show that the reduced combustion reaction system obtained by CSP method approximates the original system well. 典型COCH4Air混合燃烧反应系统的计算结果表明,由计算奇异摄动法得到的简化燃烧反应系统是原燃烧反应系统很好的近似。
Thermal sensitivity is a measurement on how easily fast chemical reaction will happen. The essence of studying thermal sensitivity of energetic materials is to find the relationship of time to maximum rate ( TMR) and the decomposition temperature. 热感度是物质在热作用下发生快速化学反应难易程度的度量,求取含能材料的热感度的本质是求取诱导期TMR与温度的关系。
