A novel form of diffusion battery uses a series of 635-mesh screens instead of the customary cluster of circular tubes or holes. Fifty-five screens are arranged in series so that the amount of aerosol penetrating through different numbers of screens can be measured with a condensation nuclei counter. This "filter stack" must be calibrated because theory is not available to calculate the performance of such screens with sufficient accuracy. For calibration a polydisperse aerosol such as ambient or silver aerosol is used to compare the performance of the screens with that of the cluster-tube and collimated-holes diffusion batteries, whose performance is known from theory. It was observed that a given number of screens is equivalent to a given number of batteries independent of the size or size distribution of the aerosol. This filter stack is very compact and light in weight (0.9 kg). It is particularly useful for measurements in the field.
一种新型的扩散电池采用了一系列635目筛网，而不是传统的圆形管簇或孔簇。55个筛网串联排列，这样就可以用凝结核计数器测量穿透不同数量筛网的气溶胶量。这种“滤层组”必须进行校准，因为目前还没有理论能够足够精确地计算出此类筛网的性能。在校准时，使用多分散气溶胶（如环境气溶胶或银气溶胶）来将筛网的性能与簇状管和准直孔扩散电池的性能进行比较，后两者的性能可从理论上得知。据观察，给定数量的筛网等同于给定数量的电池，这与气溶胶的大小或大小分布无关。这种滤层组非常紧凑且重量轻（0.9千克）。它在野外测量中特别有用。
