降速干燥 meaning in English

falling rate of drying
falling-rate periods of drying

Abstract : according to analysis of drying characteristics of granular product , the paper dscribed analytical solutions on a single grain with two falling rate drying stages during corresponding falling rate drying periods of deep - bed drying process the changes of drying and physical parameters ， and their corresponding relation were discussed . a mathematical model was developed and analytical result was presented by computation . the potential application of this analytical solution was alsogiven in this paper
