airflow stability

sensibility and airflow stability of mine ventilation system

矿井通风系统的敏感性和风流稳定性

It is necessary to study the mine ventilation network airflow stability in mine.

本文首先对矿井通风网络方面的研究现状做了必要阐述.

it is necessary to study the mine ventilation network structure to ensure the airflow stability in mine.

the airflow stability degree of each branch has been got through calculating the airflow power index.

根据风流功率指标，确定各分支的风流稳定性程度。

simultaneously, the ventilation system of the stability and reliability are closely related, so the study of stability joined the airflow stability.

由于通风系统的稳定性又与可靠性密切相关，所以在研究可靠性的同时考虑了风流稳定性的研究。

it selects the main factors that affect the airflow stability by rough set theory.

该方法首先应用粗糙集理论来选择影响风流稳定性的重要因素。
