PROGRESS语言

PROGRESS语言是一种非可视化的编程语言，符合4GL规范，具有高级语言的优点，可以进行条件选择（IF、WHERE）、嵌套循环（FOR）、计算（如求和、求平均）等操作，还可以直接进行打印、显示（PUT、DISPLAY），并且不区分大小写。

PROGRESS源程序一般由4部分组成：全局变量定义、图形变量定义（一般是用户指定的查询选择条件）、输出数据的格式和主程序（如何利用数据库中的字段生成用户需要的正确数据）。 全局变量的定义

全局变量用DEFINE VARIABLE 关键字定义。格式如下：

DEFINE VARIABLE W1 LIKE（数据格式INTEGER，CHARACTER??） DEFINE VARIALBE W2 AS VARIABLE2

使用AS可以直接引用已经定义好的数据格式。比如我们要把某个变量定义成和表中的字段类型一致时，可直接定义如下： DEFINE VARIALBE1 AS 表中定义的字段

这样我们就不用再到后台数据库中去查询该字段的数据格式，提高了编程速度。如果这个变量在调用过程中也要用到，则分别定义如下： //在主过程中

DEFINE SHARED VARIABLE W1 LIKE （数据格

The Origins of MPI

Over the past ten years,the message-passing paradigm has been shown to be both a practical and ef?cient way of programming Distributed Memory(DM)MIMD par-allel systems.However,the take-up of such machines by the scienti?c community,even when there were manifest hardware cost performance bene?ts,has been painfully slow.One of the reasons for this slow acceptance of par-allel machines has been concerns about software devel-opment cost and the lack of portability of

Abstract 摘要

The task of information processing, or computation, can be performed by natural and man-made ‘devices’. Man-made computers are made from silicon chips, whereas natural ‘computers’, such as the brain, use cells and molecules. Computation also occurs on a much smaller scale in regulatory and signalling pathways in individual cells and even within single biomolecules.

1. Introduction

Turbulence is a frequently occurring phenomenon in the boundary layer and may pose a threat to low-flying aircraft and aircraft during the take-off and landing phases of flight. In addition, gusty surface winds, the manifestation of turbulence in the boundary layer, may also be a hazard to ground transportation and enhance fire danger. Therefore, a nu

铁素体不锈钢固体氧化物燃料电池中，镀膜、修饰、合金材

料的研究进展

摘要：铁素体不锈钢材料并非专门为了作为连接材料而设计，但现在已经成为固体燃料电池（SOFC）中标准的连接材料。人们容易在市场上购买该材料，然而它的使用，特别是作为阴极材料使用时，会呈现出了一系列问题，这也是导致燃料电池早期衰退的原因。上诉的问题有：瞬变电阻的快速增长和氧化物中铬的蒸发，引起阴极铬中毒使电池失效。在过去的几年里，研究人员为了避免此类问题的发生，设计了各种传导/防护材料、表面修饰材料和合金材料。本文客观地综述了目前的相关研究，将不同的方法进行了分类、总结，并一一举例说明。最后，对未来该领域的研究做了展望。
