The rainfall Intensity Duration Frequency formula is one of the bases in hydrology calculation, and has been of considerable interest to engineers and hydrologists. 降雨公式是水文计算的基本依据之一,也是工程师和水文学家十分关心的问题。
Exercise intensity, duration, frequency, and other factors appear to play important roles in anti-aging outcomes, as does the role of training. 运动强度、时间、频率和其他因素以及训练的作用往往对抗衰老结果起着重要的作用。
Conclusion High intensity, long duration and repeated high frequency electric stimulation will degrade the excitability of nerve fiber. 结论高强度、长时间、快速反复的电刺激将使神经纤维兴奋性降低。
When the laser intensity and pulse duration are fixed, with the increase of vibrational quantum number, the multi-photon resonance transition frequency becomes smaller, which is consistent with the energy level distribution of non-harmonic oscillator. 当激光的强度和脉冲持续时间一定时,随着振动能级的升高,各级多光子共振跃迁的频率越来越小,说明了能级间隔越来越密,这与非谐振子的能级分布相吻合。
