The decisive factor is that the differentiation is not based on a sample over a discrete time period, but is a physical effect, so that the user sees a dynamic, low-noise acceleration signal.
决定性的因素是这种区分是没有根据的样本离散多时间,但它是一个物理作用,使用户会看到一个充满活力,低噪声加速度信号。
The dynamic effect of wind induced vibration is not outstanding, and the moment pressure enlarging effect of the fluctuation wind can be approximately considered by the gust factor.
膜面的风振动力效应并不显著,可以近似采用阵风系数来考虑脉动风的瞬时增压作用。
