Decreasing in breathing frequency could improve the particle deposition efficiencies. Nonethless, decreasing respiratory volume may enhance the particle deposition efficiency.
若是减少吸入的呼吸流量，微粒子在气管内的沈积效率也会随之增加。
Another experiment demonstrated that physical exercise, which was sufficiently vigorous to double the rate of breathing, had no effect on the frequency of yawning.
另一项实验表明，体育运动——尤其是剧烈的运动——可以使呼吸频率增加一倍，但这对打哈欠的频率没有影响。
Called MyCalmBeat, the app USES a heart rate monitor that attaches to the ear to detect a person's optimal breathing rate, or resonant frequency, which is unique to each person.
这个应用名为“My CalmBeat”，它利用一个附在耳朵上的心率监测器来探测每个人独特的最佳呼吸频率，或者说是共振频率。
Combining the helium and hyperoxia slows down the frequency of breathing while making the air easier to breathe.
氦氧联用减慢了呼吸频率从而使空气更容易呼出。
The resonators, oscillate at the same frequency in a combined elongating (or breathing) mode and bending mode.
这些谐振器按照组合的拉长(或呼吸)模式和弯折模式以相同的频率振荡。
The second key to breathing with high frequency and high efficiency lies in how you roll to the side to take that breath.
呼吸时保持高频率以及高效率的第二要义，取决于你如何转体至呼吸侧。
The second key to breathing with high frequency and high efficiency lies in how you roll to the side to take that breath.
呼吸时保持高频率以及高效率的第二要义，取决于你如何转体至呼吸侧。
