对高度远小于宽度的近抛物线形浅微通道内的流体动力弥散进行了实验研究。使用长蛇形通道和旋转混合器两者。实验结果表明，色散与沟道的宽度有关，而与沟道的高度无关。结果与最近提出的浅通道色散理论定量一致。
Hydrodynamic dispersion in shallow microchannels with almost parabolic cross-sectional shapes and with heights much less than their widths is studied experimentally. Both long serpentine channels and rotary mixers are used. The experimental results demonstrate that the dispersion depends on the width rather than the height of the channel. The results are in quantitative agreement with a recently proposed theory of dispersion in shallow channels.
