旋流浮选器无维变量模型的建立

主要介绍喷气式流体旋流浮选器细煤浮选过程的模拟与分析课题的第一部分，即无维变量模型的建立与分析。具体研究浮选器中涡流定向器出口面积与下部环状开口面积之比Ａ＊，以及空气流量与煤浆流量之比Ｑ＊和各浮选参数之间的关系。提出并建立了无维变量模型，给此类浮选器的实验与应用建立了理论基础，同时为浮选器整个系统的模型建立提出了方向。文中建立的无维模型也可供其它细矿浮选过程参考。

On Feasibility of Variable Separation Method Based on Hamiltonian System for a Class of Plate Bending Equations

The eigenfunction system of infinite-dimensional Hamiltonian operators appearing in the bending problem of rectangular plate with two opposites simply supported is studied. At first, the completeness of the extended eigenfunction system in the sense of Cauchy＇s principal value is proved. Then the incompleteness of the extended eigenfunction system in general sense is proved. So the completeness of the symplectic orthogonal system of the infinite-dimensional Hamiltonian operator of this kind of plate bending equation is proved. At last the general solution of the infinite dimensional Hamiltonian system is equivalent to the solution function system series expansion, so it gives to theoretical basis of the methods of separation of variables based on Hamiltonian system for this kind of equations.
