A color visualization-based image processing method is developed in this paper to quantify the concentration evolution of the Brilliant Blue FCF transport through a two-dimensional homogeneous porous medium. A series of images are recorded at known time intervals, then the spatial distribution is estimated using a calibration curve, linking the gray pixel value to the solute concentration. Using a multi-dimensional concentration distribution map extraction technique the longitudinal and transverse concentration distributions could be observed with the physical model. The image-processed concentrations are then compared directly with the measured concentrations sampled at the outlet end. The tracer breakthrough curves sampled at multiple points along the central line of the medium are also compared with the solutions from the standard advection–dispersion equation model. It is shown that the non-invasive image processing method may be used to map the spatiotemporal evolution of a solute’s concentration without disturbing the flow or the transport dynamics, although the measured solute breakthrough curves feature some non-Fickian dynamics that cannot be efficiently captured by the standard transport model.

人到老年，生活节奏放慢，一切以“柔”字为前提，会对养生大有益处。 说话柔和。语速放慢、音调放低。缓慢的语速和低柔的音调可以使老人大脑变得安静，肌肉容易放松，气血畅通，身体各部分机能组织运转都会变得更协调。而且，老年人慢条斯理地说话，有利于理清自己的表达思路，正确表达自己的要求和观点。 饮食柔暖。老年人牙齿松动、津液亏损、肠胃功能逐渐虚弱，应少吃不易消化和刺激性的食物。食宜缓、淡、暖，不要吃冷饭
随着人们生活水平的提高和养生观念的增强，进补已成为许多人的健康选择。尤其是老年人、平时体质较弱或病后体虚者，更想通过进补（药补与食补）来增强体质。然而其中不少人在进补相当一段时间后，并没有收到应有的功效，有的甚至还出现了不良反应。这是什么原因呢？遇到这种情况是停止进补，还是继续进补呢？笔者认为，凡遇此种情况，就应认真检查一下自己进补的全过程，从以下几个方面找出原因，然后针对主要症结进行调整，方能取
