当到了临界的压力和温度条件下，谱峰开始发生变化，出现新的谱峰，这些产物

When the critical pressure and temperature conditions are reached, the spectral peaks begin to change, and new spectral peaks appear. The Raman spectra of these product phases already show weak signs under in-situ high temperature and high pressure conditions. After quenching, the Raman spectra of Peak characteristics are displayed more clearly.
