According to the behavior of the combined process of multicomponent molecular diffusion and Knudson diffusion in porous catalysts, a set of second order nonlinear ordinary differential equations describing the concentrationprofiles of reactants and products for a single reaction in an isothermal spherical catalyst has been developed in this paper. In these differential equations, the concentration gradients of different reaction components are strongly coupled together. By using shooting method to solve the two-point boundary value problem posed by this set of equations, the concentration profile of each reaction component and the numerical solution of effectiveness factor can he obtained. Because of the differences between the effective diffusion coefficients of the reaction species, the relations between the changes of their compositions in catalyst no longer obey the stoichiometric relations of the reaction. When the intraparticle diffusion restriction is serious, in the catalyst it may appear a "dead zone", in which the concentrations of the reaction components are asymptotic to the equilibrium concentrations and the chemical reaction practically does not proceed. As the "dead zone" exists, applying this mathematical model and the solution procedure, the radius of "dead zone" and the effectiveness factor under this condition can be solved. The cylindrical sh.ape catalysts commonly used in industry are treated as spheres of equal specific external surface.

本文按多孔催化剂内多组分分子扩散及努森扩散联合过程的特性,导出了描述等温球形催化剂内单一反应的反应物和产物浓度分布的二阶非线性常微分方程组.微分方程中各个反应组分的浓度梯度强烈相互耦合.在计算机上用打靶法求解此常微分方程组提出的两点边值问题,即可求得各个反应组分的浓度分布和催化剂效率因子的数值解.由于反应组分的有效扩散系数间的差异,催化剂内反应组分的组成变化之间的关系不再符合反应的化学计量关系.当内扩散过程的阻滞作用严重时,催化剂颗粒内会出现“死区”,死区内反应组分的浓度趋近于平衡浓度,实际上不再继续进行反应.存在死区时,使用此数学模型及解题方法可求出死区的半径及此情况下催化剂的效率因子.工业上常用的圆柱状催化剂按照相等比外表面积的球体处理.

It has been known that the most satisfactory method of determining rate constants and activation parameters is a full steady-state line-shape fitting orer the temperature range where exchange effects can be observed. For weakly coupled systems undergoing exchange it is possible to compute theoretical ine shapes using modified Bloch equation, but strongly coupled systems require a full density matrix (DM) treatment. The aim of this paper is to show how-to calculate line-shapes using the DM method. The paper consists of the basic theory of DM and the applications of DM theory to NMR line-shape calculations of inter- and intra-molecular exchanging systems.

From the characteristics of velocity admittance, a method of identification of modal parameters is developed by way of smoothing the measurements of frequency response of velocity. Several numerical examples show that this method is able to obtain the modal parameters of discrete or continuous systems and can be applied to the damped system which cannot be diagonalised. Moreover, the separation of strongly coupled modes can well be considered in the presence of neighbouring damping ratios and for a very high...

From the characteristics of velocity admittance, a method of identification of modal parameters is developed by way of smoothing the measurements of frequency response of velocity. Several numerical examples show that this method is able to obtain the modal parameters of discrete or continuous systems and can be applied to the damped system which cannot be diagonalised. Moreover, the separation of strongly coupled modes can well be considered in the presence of neighbouring damping ratios and for a very high modal density, for exampleThe representation of velocity admittance in the complex plan is well restituted in the range of frequency studied.In this paper, the author introduces non-dimensional coefficients so that the method may be made to extend the range to over 20 KHz.

根据速度导纳的固有特点,作者首先提出了拟合实测的速度导纳数据来识别模态参数的方法。几个数字例子和实验结果表明: 1) 能精确地获得离散系统的模态参数,也能获得较好精度的连续系统的模态参数; 2) 不仅能应用于比例阻尼系统,而且亦能应用于非比例阻尼系统; 3) 特别适合于模态十分密集的情况,如两个相邻模态阻尼比十分接近且频率分离比(f_(r+1—f_r)/f_r 0.001的条件下,也能获得较满意的结果。 在所研究的频率范围内,实测的和识别的速度导纳都表示在同一复平面内(速度导纳图),以便比较。 本文还引用了无量纲频率,致使此方法适用的频率范围扩充到20KHz以上。
