Perturbation to Mei Symmetry and Generalized Mei Adiabatic Invariants for Nonholonomic Systems in Terms of Quasi-Coordinates

Abstract

By introducing the coordination function f, the generalized Mei conserved quantities for the nonholonomic systems in terms of quasi-coordinates are given. Then based on the concept of adiabatic invariant, the perturbation to Mei symmetry and the generalized Mei adiabatic invariants for nonholonomic systems in terms of quasi-coordinates are studied.

Pressurized Microwave-Assisted Extraction of Total Isoflavones from Pueraria Lobata

“…Through the single factor and response surface tests, the optimal technical conditions were determined to be: power700W, ratio of liquid to solid 10.45, pressure 132.61kPa, alcohol mass concentration 51.2 %, pre-immersed time 2 h and particle size 80 meshes. Under these conditions the maximum total isoflavones extraction efficiency reached 98.75% which is 23.5% higher than that obtained at atmospheric pressure [9].The established model was proved to be consistent with the experiment and can be applied to predict the extraction efficiency at different technical conditions.…”
