So can ensure adjustable laryngeal orifice and dynamic response performance and reduce oven pressure difference fluctuation range.
因此可以保证可调喉口的动态反应性能及减小炉口压差波动范围。
Pressure difference fluctuation is employed to identify flow pattern and pressure difference fluctuation signals of various flow pattern are obtained.
采用压差波动法测定流型，获得了不同流型下的压差波动信号。
Pressure difference and Cd concentration fluctuation may cause the noise to increase many times with the latter mainly enhancing the noise in the low frequency range.
气压差及镉浓度波可使噪音增大很多倍，浓度波主要增强了低频噪音。
