考虑了基于拉普拉斯变换的传递函数F(P)在分析停留时间分布曲线中的应用。将其应用于两点测量技术，结果表明，对于较低的τp(测点间平均停留时间，τ算符)，所有模型都给出了相同的F(P)。对于通过填充床的流动，建议将τp值限制在2.0-5.0范围内，以获得一致的分散参数结果。响应曲线的随机波动的影响使得平滑它们也是必要的，特别是对于放射性示踪剂响应。
The use of the transfer functionF(p), based on the Laplace transformation, in the analysis of residence time distribution curves is considered. It is applied to the two point measuring technique and it is shown that for a low τp(τ mean residence time between measuring points,pLaplace operator) all models give the sameF(p). For flow through packed beds, τpis recommended to be within a restricted range of 2·0–5·0 to give consistent results of the dispersion parameters. The effect of random fluctuations in the response curves is such that smoothing them is also necessary particularly for radioactive tracer responses.
