An comparative analysis is made between the results of the site test and that of the FEM computation. The difference of neutral point depth between them are also explained by analyse.
对现场试验与有限元模拟的成果进行了对比分析，并对得出的中性点深度相差较大的原因作了分析。

SONDERMANN filters are used to remove, by means of depth-type or surface filtration, both organic and inorganic contaminations from aggressive and neutral liquids.
SONDERMANN过滤器通过深度和表面过滤用来从活跃和中性液体中去除有机和无机杂质。

Rapid increase of aerosol optical depth and coarse particle concentration, as well as aerosol neutral or anomalous extinction was observed during dusty periods.
