     In Chapter 2, the author proposes two new dependent Fletcher-Reeves conjugate gradient methods arising from different choice for the scalarβk and make two different kinds ofestimations of upper bounds of \βk \ with respect to βkFR, which are based on Abel Theorem of non-convergent series of positive items.
     第二章提出了两种新的相关FR方法,它们主要表现在共轭梯度法中参数β_k相对于β_k~(FR)的选取上。 这里给出了|β_k|与β_k~(FR)之比的两种非常宽松的上界估计值,它是建立在关于发散级数的Abel定理基础上的。

  fr method
In this paper, we take a little modification to the Fletcher-Reeves (FR) method such that the direction generated by the modified method provides a descent direction for the objective function.
      
Moreover, the modified method reduces to the standard FR method if line search is exact.
      
The frequency response (FR) method has been applied to study the dynamics of cyclopropane adsorption in faujasite, mordenite, beta and ZSM-5 zeolites containing Br?nsted or Lewis acid sites in the concentration range of 0.586-0.772 meq/g.
      
One of the characteristic examples of the inability of the classical linear frequency response (FR) method to identify the correct kinetic mechanism is adsorption of some substances (p-xylene, 2-butane, propane or n-hexane) on silicalite-1.
      
A valuable feature of the FR method, at least for simple systems, is the relative position of the in-phase and out-of-phase spectral components.

This paper presents a new method, FR method, to solve the inverse problems of acoustic wave equations. FR method is a general numerical inversion algorithm of acoustic wave equations. It can be used to one, two or three dimensional inverse problems with any different boundary conditions. The basic principle and formulae are derived carefully in the paper, and numerical examples of one and two dimensional inverse problems are given. The numerical results show the accuracy and stability of the method.
