white-noise level

基本解释

When the white noise level was 30% and 5-year running average was used, low biomass corresponded to high surplus production.
白色噪音水平为30%且应用五年移动平均时，低生物量对应高剩余产量；
An improved fractal image denoising algorithm for removing additive white Gaussian noise(AWGN) was presented by adopting quadratic gray-level function.
提出了一种针对加性白高斯噪声（AWGN）的改进分形图像去噪方法。
And watched three-spined stickleback fish hunt water fleas, to the accompaniment of either white noise calibrated to match the noise level of speedboats or a silent track as a control.
并控制三刺鱼在跟快艇噪音程度相当的白噪声中，或者完全安静的环境之下，观察它们捕食水蚤的情况。
