Identification of Concentration and Residence Time Distributions with One-Dimension Diffusion Model at Close Boundary Conditions
Journal Title: Science Paper Online - Year 2006, Vol 1, Issue 1
Abstract
The paper identified the concentration and residence time distributions by analytically solving Laplace transformation of a one-dimension diffusion model. The model was built-up at the close boundary conditions with the pulse input of the tracer into reactor. The response curves of concentration at the outlet of reactor were presented at the different values of Peclet number. Furthermore, the changes of the concentration with time and location in the reactor were described for a fixed Peclet number. The comparisons of the response curves of the concentration were made for the open and close boundary conditions. Also, the characteristics of residence time distribution were discussed.

红树植物水黄皮pongamia pinnata中<br /> 一个生物碱的分离与结构表征<br />
利用各种层析手段,从海南红树植物水黄皮pongamia pinnata的正丁醇部分中分离纯化了一个生物碱类化合物,通过各种波谱实验(1D-NMR,2D-NMR, ESI-MS)确定其结构为:dehydrocorydaline(1)。该化合物为首次从红树植物水黄皮中分离得到。
一类含中立项的非线性系统的复合抗干扰控制方法
针对一类含中立项的非线性系统,提出一种基于干扰观测器设计和H∞控制的复合抗干扰控制方法。将输入通道中的干扰信号表示为1个动态子系统,可以涵盖常值、谐波等信号。被控对象和干扰子系统都含有参数和结构不确定性。基于线性矩阵不等式,...
基于模糊最小二乘支持向量机的发酵过程建模研究
青霉素发酵过程具有时变性和高度非线性,对菌体浓度等的在线测量十分困难。最小二乘支持向量机建模,虽然提高了预测速度,但是预测精度有所欠缺。为提高预测精度,本文在最小二乘支持向量机中引入模糊思想,采用一种基于类中心距离的模糊...
