The dual-reflex bandpass, due to the fact that its ports control cone motion over a wider range of frequencies, produces the least distortion and exhibits the best power-handling characteristics.
双反射带通箱，由于它的导向孔在很大的频率范围内控制了锥盆动作，所以产生的失真最小，同时还表现出最好的功率承受特性。
Results Compared with group E, group ES offered better anesthesia for LMA insertion, less swallowing reflex and body motion, and more stable haemodynamics.
结果ES组能提供更好的喉罩置入条件，且能减少舌咽反射和肢体反应， 更能保证喉罩置入时血流动力学的稳定。
