The flow to open design is adopted, and the medium flow direction tends to the opening direction of the valve with good controllability of small opening and low flow characteristicdistortion.
采用流开式设计，介质趋向于阀门开启的方向，小开度可控性好，流量特性畸变小。

The Harmonious Distortioncharacteristic of telemetry seismic data acquisition systems is an important performance index, which affects the quality of seismic acquisition data directly.
谐波畸变特性是遥测地震数据采集系统的一项重要性能指标，直接影响地震数据采集的质量。
