The efficiency of mass transfer in 60% fraction of hole is higher than in 40% fraction of hole. When gas/liquid ratio is lower 10, the efficiency of mass transfer in new sieve baffle tray is higher than in traditional tray.A three-dimensional quasi-single phase computational fluid dynamics program with the RNG- turbulence model is presented for evaluating the performance of the new sieve baffle tray. The special feature of this model is taking into account the influence of heat transfer during the mass transfer and the influence of mass transfer in computing the flow field.

建立了以RNG模型为基础的三维拟单相流模型，该模型与其它研究者所建立的模型的最大进步是，前人在塔板流场的计算中没有考虑传质的影响，并且在传质过程中没有也没有考虑传热对传质产生的影响，实际上在传质过程中，抛开传热来计算和研究传质是不准确的，因为在传质过程中伴随着传热，并且传热和传质是互相影响、互相制约的，本文所建立的传热与传质模型，把传热和传质进行了有效的藕合。

高频筛效率高、振幅小、筛分频率高。与普通筛分设备的原理不同，由于高频筛采用了高频率，一方面破坏了矿浆表面的张力和细粒物料在筛面上的高速振荡，加速了大密度有用矿物和析离作用，增加了小于分离粒度物料与筛孔接触的概率。

Firstly, this paper investigated roundly the basic theory of the ambient vibration method, analyzed systematically the main methods of ambient vibration identification, and discussed their advantages and disadvantages. Then we established the finite element model of structural dynamics and test model and analyzed their mutual relation, improved MUSIC method and correlation function method in the harmonic identification, and gave the subspace method and correlation function method based on continuous model, which is multi-harmonic retrieve technique. And then, this paper also puts forward least-squares method to estimate directly structural physical and modal parameters; this approach replaced the derivative operator in the continuous time model with an equivalent approximation, and estimated the physical parameters of structures by the least-squares method. And then, we discussed the approximation methods of derivative and their convergence. Finally, this paper researched the modal parameters of a frame structure by the simulation and test. The results demonstrated that subspace method, correlation function method and the least-squares method are effective and stable respectively.
