A measuring approach of pressure oscillation has been developed and experiments are conducted in a 10 liter two-dimension air-lift loop reactor. The experimental results show that the local mass transfer parameters have close relationship with the operating conditions, the structure of ALR and the properties of the reaction systems. A series of measurements of pressure pulse indicate that a gas distribution zone exists near the gas sparger, and in this zone the responding signals of pressure pulse are different with the signals measured in other parts of the reactor.

对不同结构的环流反应器的局部流体动力学和传质动力学特性进行了研究，利用压力传感器测量了空气-水、空气-NaCl水溶液、空气-Na〓SO〓水溶液、空气-葡萄糖水溶液和空气-乙醇水溶液五种体系，在不同气速下，不同位置的压力脉动信号，通过随机信号的数学分析，得到压力脉动信号的频谱特性，并依据压力脉动信号的频谱特性的分析给出环流反应器气体分布区的范围。

On the problem of model parameter determination, the singularity distribution method is used to derive the expressions for numerically calculating the added mass arised from vibration of the structure under three-dimensional case; The aero-dynamic damping ratio is identified from the testing data based on the methods of empirical mode decomposition, improved random decrement and Hilbert transformation; The reduced-order spectral representation method is also deduced in this chapter based on the technique of proper orthogonal decomposition.

Starting from the spectral representation of quasi-particles, when Debye screening mass and finite width of the particle are taken as parameters into the spectral functions, we will get effective propagators of quarks and gluons, and then establish the effective perturbation theory which reflects directly collective effects in QGP, and analyse some thermodynamics problems about soft partons in QGP.
