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。
