On the study of combustion process of internal combustion engines, the combustion process is usually studied in the time region.
在内燃机燃烧过程的研究中，通常把燃烧过程在时域上展开，即制取示功图。

In order to study the fuel mass flow rate regulation characteristics of tube-in-hole for solid fuel ramjet, the flow field of turbulent combustion was numerically analyzed.
The study also shows that the ignition and combustion of boron particle lie on the resorting time and the environment temperature, and have no direct relationship with after-burning chamber's length.
