上期回顾:上期,本篇文章主要介绍外源性蛋白酶对氨基酸消化率的影响及其超蛋白效应。外源性蛋白酶能够影响氨基酸回肠消化率,氨基酸在所讨论日粮或饲料中的固有消化率是影响其作用程度和一致性的主要因素(见上文)。其他可影响外源性蛋白酶对氨基酸回肠消化率本身作用的因素尚不清楚,但可能与进入的蛋白质的三级结构及其特性有关,如:球状、纤维状、疏水性或极性等,还有可能与可导致内源性蛋白质流失增加的抗营养因子的存在有关。这两个因素(底物与外源性蛋白酶的相容性和蛋白质类抗营养因子的存在)可能主要影响效应本身的应答程度和一致性。

In this paper we present a first supercloseness analysis for higher-order Galerkin fEM applied to a singularly perturbed convection-diffusion *** a solution decomposition and a special representation of our finite element space,we are able to prove a supercloseness property of p+1/4 in the energy norm where the polynomial order p≥3 is odd.

In the present paper the edge stabilization technique is applied to a convection-diffusion problem with exponential boundary layers on the unit square, using a Shishkin mesh with bilinear finite elements in the layer regions and linear elements on the coarse part of the mesh. An error bound is proved for ‖πu-u^h‖Е, where πu is some interpolant of the solution u and uh the discrete solution. This supercloseness result implies an optimal error estimate with respect to the L2 norm and opens the door to the application of postprocessing for improving the discrete solution.
