The @S06075@ of atomized component in the component consumed. The efficiency of atomization is measured in a given part of the flame, usually the observation space; \(ɛ_{\text{a}}=ɛ_{\text{n}}\ \chi _{\text{s}}\ \chi _{\text{v}}\ \chi _{\text{a}}\). The signal is a function of the product \(q_{\text{v}}\ ɛ_{\text{a}}\), but \(ɛ_{\text{a}}\) is also a function of \(q_{\text{v}}\), usually decreasing at high volume rates.
