在水一方2867

金虫 (正式写手)

[交流] 帮忙翻译一下 急急急!!!

The pictures in the figures show the random advection of the dye downstream of the injection point(for about three integral scales). Dye is passively transported by the flow, as odours are. Odour detection events correspond to encounters with dye concentrations above a threshold fixed at about five times the average intensity level. The mean velocity (pointing downward in Fig.3) is about  4cm/s (its measurement by olfactory  robots might be realized using standard anemometers ), and the root-mean-square velocity is about 30% of the mean velocity, giving a Reynolds number of ~10^3. Snapshots of the filed are acquired at a frequency of 200Hz. Coherent odour patches make the searcher spiral around the location of the encounters due to correlations among the detections. Yet, the resulting search process is just twice as long as for a model with independent hits, and might be further accelerated by accounting for time-correlations, as detailed in Supplementary Information.

图解中的图片表明注入点下游染料的随机水平流动,染料和气味一样随流体流动传输。 当遇到染料浓度达到阚值即五倍平均强度水平开始进行臭气检测。平均流速(图3中指向下面)是大约4cm/s(用具有标准风速计的嗅觉机器人测定)均方根速度大约是平均速度的30%,雷诺数达到10 3。快照图是在200HZ频率下获得的。由于检测之间的联系,气味斑块使得探针绕着相遇的地方旋转。最终探测时间是测定单独参数时间的两倍,解决了时间之间的联系后速度会进一步加快,详细信息见补充说明。
