The results showed that the decomposition of 4-nitroimidazole began with the split of the C—NO2 bond in the temperature range of 185—210℃. The strongly oxidative product NO2 destroyed the instable annulus of 4-nitroimidazole instantly, all the other C＝N, C＝C, C—H and N—H bonds of the five membered ring were broken simultaneously, and the detected gas products of 4-nitroimidazole decomposition were NO2, CO2 and CO.

结果表明，4-硝基咪唑的催化热分解起始于其分子中C-NO2化学键的断裂，温度范围是185~210℃。C-NO2键的强氧化性的裂解产物NO2瞬间作用于4-硝基咪唑分子中不稳定的五员环，使化学键C=N、C=C、C-H和N-H同时被打破。4-硝基咪唑的气体分解产物包括NO2、CO2和CO。

Methanol molecule participates in the proton transfer process, which takes place by a intermolecular six-membered proton-transfer transition state structure instead of the intramolecular four- membered. Consequently, the activation energy of the proton-transfer process is reduced greatly,resulting in the carbon-carbon bond formation process become the rate-determining step. The results are consistent with Aggarwal's the latest dynamics experiments.

CH3OH分子参与质子转移过程，使得原本通过四元环结构过渡态的质子转移过程通过六元环结构过渡态实现，从而极大地降低了质子转移过程的活化能，碳-碳键形成过程进而成为反应的速度控制步骤，研究结果与Aggarwal等的最新动力学研究成果相吻合。

On the basis of Raman and FTIR spectra research on melt structure and water solubility mechanism in albite glasses, we can make the following conclusions:(1) Higher pressure (1bar-2. 0GPa) can lead to below frequency region (50-650cm〓) shift to higher frequency and become narrower, and result in high frequency region (850-1300cm〓) move to lower wave number and become narrower at the same time. These are consistent with the decrease of average T-O-T angle and distribution scope of bond angles (0). In addition, the intensity of 580cm〓 band decrease with increase of pressure and the changes are obvious while pressure is in the range of 0.8-1. 0GPa. And these result from the"collapse"of the planar three membered -containing rings within the glass structure.

通过对高温高压下钠长石熔体结构及水在钠长石熔体中溶解机制的Raman和FTIR光谱实验研究，可以得出以下结论：(1)随着压力升高(1bar-2.0GPa)NaAlSi〓O〓熔体玻璃Raman光谱的低频区(50-650cm〓)不断变窄并向高频方向移动，同时高频区(850-1300cm〓)不断变窄且向低频区方向移动，这表明随着压力升高T-O-T键角不断减小，并且分布范围变窄，T-O-T键角这种变化从而可使T-O键的力常数减小，导致键强减弱；另外，580cm〓谱峰强度随着压力升高不断减弱，并在0.8-1.0GPa时最为显著，这是由于在0.8-1.0GPa时包含的平面三元环结构的"垮塌"造成的。

During mercerization, ramie fiber is swelled, and consequently the distance of cellulose molecules increases, and the hydrogen-bond between molecules is weakened, and even broken.
