随着边缘计算需求激增,云边协同成为未来重要演进方向,云边协同发展的难点之一是对边缘端及运行于其上的应用的部署、管理和更新升级,而容器技术为解决以上问题提供了思路。基于容器技术轻量化、部署快、易移植的特点,研究了基于容器化的云边高效应用管控方法,包括在云边协同的总体架构中增加容器设计、基于容器进行应用协同设计;研究了云端部署更新管理机制;对容器的应用部署及更新、容器及应用下发等设计内容也进行了研究和实现。通过实验验证,该方法在系统能耗、效率、计算时延和云端CPU(中央处理器)使用效率方面得到了显著提高,进而使系统更新速率、服务器可用边缘节点数量以及处理的数据容量都有所提升,能够大幅度对云边协同系统进行优化,同时也大幅度提高了整体系统的计算能力。通过该技术的应用可以改善智慧用电平台边缘侧计算资源紧张、边缘设备异源异构、服务管理需求复杂多样等问题,实现了智慧用电云边协同平台的高效应用管控。

Six anticorrosion primers were prepared respectively by using two fire retarders-APP and DBDPO. Properties of these primers were determined with four test methods-salt water immersion,salt water spray test,determination of impedance of coated steel and C. R. M. Results show that APP with definite water-soluble property reduced anticorrosion performance of the primers,while non water-soluble DBDPO would not affect the anticorrosion properties of the primers if the Pigment Volume Concentrations(P. V. C)were well calculated.

As usual, denote by KWr[a,b] the Sobolev class consisting of every function whose (r-1)th derivative is absolutely continuous on the interval [a,b] and rth derivative is bounded by K a.e. In [a,b]. For a function f ∈ KWr[a,b], its values and derivatives up to r-1 order at a set of nodes x are known. These values are said to be the given Hermite *** work reports the results on the best quadrature based on the given Hermite information for the class KWr[a,b]. Existence and concrete construction issue of the best quadrature are settled down by a perfect spline interpolation. It turns out that the best quadrature depends on a system of algebraic equations satisfied by a set of free nodes of the interpolation perfect spline. From our another new result, it is shown that the system can be converted in a closed form to two single-variable polynomial equations, each being of degree approximately r/2. As a by-product,the best interpolation formula for the class KWr[a,b] is also obtained.
