software portability

The portability of I/ O software can be evaluated by proportion of device dependent and independent code size in the implemetation. So the paper is proved to have good portability because the proportion of device dependent code is 24.1%.

I／O软件可移植性的高低可以从设各无关及相关代码的比例进行衡量，在本实现方案中，设备相关代码仅占代码总量的24.1%，说明该方案具有较好的可移植性。

The Qt based platform interface software development system to overcome the traditional telecontrol system software user interface are not unified, the code difficult to maintain, poor portability disadvantage.

基于Qt平台开发的系统界面软件克服了传统远动系统软件的用户界面不统一、代码难以维护、移植性差等缺点。

This paper describes the concept and process of software portability engineering systematically with a design and implementation framework for portable software.
