我国有关通风除尘书刊中,风管阻力计算公式的文字符号较为混乱,这给学习、工作带来麻烦和困难,甚至可能造成工作中的失误和损失。建议有关部门和专家们能尽快统一,以利于学习、工作和国际科技交往。 In our country’s books and periodicals on ventilation and dust removal, the symbolic expressions of the wind pipe resistance formula are more confusing, which brings troubles and difficulties to study and work, and may even cause mistakes and losses in work. It is suggested that relevant departments and experts can be unified as soon as possible to facilitate learning, work, and international scientific and technological exchanges.
