毒气泄漏伤害区域评估系统研究与开发

RESEARCH AND DEVELOPMENT OF ASSESSMENT SYSTEM FOR CALCULATING THE RISKY AREA OF TOXIC GAS LEAKING

以平板模型为原理,以Visual Basic6.0和Oracle8i为开发工具,建立了一个毒气瞬间泄漏后伤害区域的评估系统。该系统根据有毒气体泄漏时的各条件参数,计算毒气泄漏后的影响区域并按照浓度划分为致死区、重伤区和致伤区。系统输出的结果为二维的伤害区域的边界,使其计算结果科学、直观和实用。

A plain diffusion pattern was used to build up a program flow chart to calculate the risky areas based on Visual Basic and Oracle. Some calculations were done according to the arithmetic process of this system, and risky areas were identified based on the concentration. The output of the system is a two-dimensional table, which enables people to easily draw the risky areas. These characters make the result more scientific and more useful.
