摘要 按照 Stolzenburg (1988) 博士建议的程序，在 1.2–20 nm 的尺寸范围内对所谓的“维也纳型”差分迁移率分析仪 (DMA) 的传递函数进行了实验研究。论文。在这项研究中，两个相同的 DMA 被用作串联 DMA (TDMA) 布置，以测量来自热丝 WOx 发生器的纳米粒子。 Stolzenburg 描述 DMA 传递函数扩散展宽的近似分析公式被观察到在从 20 nm 到 ∼ 2 nm 的范围内具有高精度。在 1.2-2 nm 标称迁移率当量直径的尺寸范围内，发现了 Stolzenburg 预测的 TDMA 输出信号形状的小偏差。
ABSTRACT The transfer functions of the so called “Vienna type” differential mobility analyzer (DMA) were studied experimentally at the size range of 1.2–20 nm following the procedure suggested by Stolzenburg (1988) Ph.D. Thesis. For the study, two identical DMAs were used as a tandem DMA (TDMA) arrangement to measure nanoparticles from a hot wire WOx generator. The approximate analytical formulae by Stolzenburg describing diffusion broadening of the DMA transfer function were observed to be valid with high accuracy from 20 nm down to ∼ 2 nm. In the size range of 1.2–2 nm nominal mobility equivalent diameter small deviations of the shape of the TDMA output signal predicted by Stolzenburg were found.
