The black box reaction can be observed, analyzed and detected in a simulation experiment, and has great significance.
This is difficult because the experiments are performed in visible capillary microtubes and require temperature and pressure control as well as microscopic observation and raman in situ measurements. The prior art mostly is the mixed taking of many equipments, and the equipment flow is imperfect, and the experiment also often only is directed at a process, and is not specially directed at the CUS.
