基于层次分析法的高校餐饮外卖APP评价研究

随着互联网的快速发展,网络已经成为现代人日常生活中不可或缺的部分。网上订餐由于其独有的便捷性,更能够轻而易举地被现代人接受。互联网上诞生的便捷订餐形式,也是电子商务应用的全新体现;从侧面来看,网上订餐也在帮助加速电子商务的应用。在高校,餐饮外卖APP的应用越来越普遍,对在校学生餐饮外卖APP的选取评价具有实际意义。文章构建了外卖APP的评价指标体系,应用层次分析法对目前市场中份额占比多的3家餐饮外卖APP—饿了么、美团外卖、百度外卖进行评价。     

Acid-Base Accounting: A Geochemical Tool for Management of Acid Drainage in Coal Mines

Acid-base accounting tests are generally used as a screening tool to delineate and define the geochemical character of different rocks. Geochemical investigations indicated that the rocks of the study area could be grouped as either acid producing or acid neutralizing. An experiment conducted in the laboratory indicates that allowing the acid mine water to drain through friable, alkaline sandstone neutralizes the mine water. This may be an inexpensive option to use at this site.     

DBDPE/协效剂/PP阻燃复合材料的合成与性能研究

将Sb2O3、Fe2O3、聚磷酸铵(APP)、镁铝类水滑石(MgAl-LDHs)、APP-LDHs、ZnO、硼酸锌等无机物分别与十溴二苯乙烷(DBDPE)复配,并与聚丙烯(PP)熔融共混制备DBDPE/协效剂/PP阻燃复合材料;采用极限氧指数(LOI)、垂直燃烧测试(UL-94)、缺口冲击、弯曲实验等方法研究了协效剂对DBDPE/无机协效剂/PP阻燃复合材料的阻燃性能及力学性能影响;采用能谱(EDX)分析样品的成分,探索APP与DBDPE复配阻燃的协效原理。结果表明,Sb2O3与DBDPE协效阻燃效果最好,APP的复配效果次之;APP与DBDPE的协效主要为体系中的磷、氮、溴元素的共同作用。

滤镜特征的归类分析与大众美图再设计赋能研究

滤镜在图形图像后期处理软件和美图APP中,是个不可或缺又极具生命力的存在。在滤镜被大众误认为能囊括一切修图功能的乱象中,本文从梳理滤镜发展脉络,厘清其与特效、美颜的关系入手,以总结其特征与归类为目的,通过分析美图APP中大众参与再设计的过程与方法,得出滤镜是开启大众美图再设计之门的有效切入口的结论。     

Application Portability Profile (APP)—The US government's Open System Environment profile OSE/1 version 2.0

Federal information systems initially developed from isolated islands of computing. Through progressive changes, these individual systems became connected by common users and common information needs. These systems are now well on the way to migrating toward computing environments that consist of distributed, heterogeneous, networked applications, databases, and hardware. The concept of a Federal computing environment that is built on an infrastructure defined by open, consensus-based standards is well on its way to becoming a de facto means of organizing these systems. Such an infrastructure is called an Open System Environment (OSE).

An Open System Environment encompasses the functionality needed to provide interoperability, portability, and scalability of computerized applications across networks of heterogeneous, multi-vendor hardware/software/communications platforms. The OSE forms an extensible framework that allows services, interfaces, protocols, and supporting data formats to be defined in terms of nonproprietary specifications that evolve through open (public), consensus-based forums.

A selected suite of specifications that defines the interfaces, services, protocols, and data formats for a particular class or domain of applications is called a profile. The Application Portability Profile (APP) integrates industry.
