Modeling of solute transport is a key issue in the area of soil physics and hydrogeology. The most common approach (the convection-dispersion equation) considers an average convection flow rate and Fickian-like dispersion. Here,we propose a solute transport model in porous media of continuously expanding scale, according to the combinatorics principle. The model supposed actual porous media as a combinative body of many basic segments. First, we studied the solute transport process in each basic segment body, and then deduced the distribution of pore velocity in each basic segment body by difference approximation, finally assembled the solute transport process of each basic segment body into one of the combinative body. The simulation result coincided with the solute transport process observed in test. The model provides useful insight into the solute transport process of the non-Fickian dispersion in continuously expanding scale. 相似文献

INTRODUCTION In recent years, modeling of solute transport inporous media remains a key issue in the area of soilphysics and hydrogeology, because anthropogenicchemicals frequently enter the soil, subsoil andaquifers, either by accident or by accepted man-agement practices, and the resulting chemicalresidues pose hazards to the environment. The movement of solute in porous media iscommonly described by the convection-dispersionequation (CDE) (Bear, 1972) developed and ex-tens… 相似文献

Blended learning has steadily gained in popularity at the higher levels of education. This marks a change in pedagogical approaches from one-directional instruction to an interactive and technology-aided class. However, to manage fluent in-class activities and proper data analysis, real-time and fine-grained data collection activities are still needed. We propose an approach which provides rich information about student activities and automates processes which are time-consuming and which otherwise require extraneous effort. First, we implemented a program to collect real-time and fine-grained data and to provide an integrated experience during in-class activities. Second, we undertook a data analysis with the collected real-time, fine-grained data. Our blended learning is a type of flipped learning with personal response systems (PRSs) of the type commonly known as clickers. We used clickers for attendance, quizzes, and daily surveys, and collected the resulting data. Our outcome shows that the blended learning approach improves student achievement levels with a relatively small standard deviation compared to traditional classes. In addition, the present findings are factors related to student satisfaction and seat position, as analyzed from the data collected using the clickers. 相似文献
