The multiplicative noise and saturation effect in a single-mode laser are investigated and the mean and normalized variance of the steady state laser intensity are calculated.
研究了单模激光中的倍增噪声和饱和效应，导出了定态激光强度的平均值和归一化方差。
As time progresses, the water saturation profile becomes closer to the steady-state profile, which corresponds to the soil-water characteristic curve of the coarse sand.
随着时间的增加，砂柱中的饱和度剖面逐渐接近于稳定时的饱和度剖面，对应于粗砂的土壤水分特征曲线。
