因而阀流通能力比一般调节阀大且无泄漏，在许用压差范围内可作切断阀用。
Thus the valve control valve flow capacity than the average large and no leakage in the range of allowable pressure shut-off valve can be used.
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。
So can ensure adjustable laryngeal orifice and dynamic response performance and reduce oven pressure difference fluctuation range.
并将压差和电耳在实际应用中，对其各自特点及适用范围作了详细说明。
The features and the applied scope of the differential pressure and electric ears in practical application have detailed been described in the paper.
