| 摘 要： | 本文分析了用脉冲法注入示踪剂时示踪剂的分布、时间与应答信号的测量,以及模型参数的回归等方面的种种误差。推荐在被测系统进口的上游适当距离处输入脉冲信号,在系统的进口和出口两个测点上用微机采集应答信号,然后用非线性回归确定模型参数。

| Abstract: | The error in experimental determination of RTD derived from tracer pulse injection,digit time and response measurement,and flow model parameter estimation are discussed.It is recommended that the imperfect pulse injection should be inputted into upstream pipe of the system at a suitable distance from its inlet,the response signals must be sampled with microcom- puter both outlet and inlet,and the least squares fitting method in the time domain is employed for flow model parameter estimation. |
