| 摘 要： | 通过对国内外计径计数法的比较，根据国外一般通风用过滤器的测试方法结合我国的实际情况对中国现行过滤器测试规范国标GBl2218—89提出一些新的建议。我国采用大气尘计径计数法测试过滤器的初始效率，该效率并不能真实反映过滤器的真实状况。为了更好的把握评价过滤器的真实使用情况，应该采用发尘量的加权平均效率进行评价。

| Abstract: | Through the comparison for domestic and international particle efficiency methods for ventilation filter performance,we make some new suggestions for Chinese current ventilation filters test standard:GB12218- - 89.China national standard regulates to test the initial efficiency of filters,but this efficiency can,t,truly indicate the true performance of filters.It is better to use the weighted average efficiency to appraise the true condition of filters according to the weight of dust fed. |
