recurrence method
2.Optimal Scheme of Fm(z) Integral Sequence Calculations in ab initio Method --Combination of Upward with Downward Recurrence Method
3.A simplified recurrence method in frequency subdomain for calculating the dynamic flexibility of complex soil foundation
4.The vibration analysis of a coupled system composed of a beam and multiple degree of freedom (MDOF) subsystem is carried out, and the analytical expressions for harmonic responses as well as the natural characteristics of this kind of system are obtained with the recurrence equation method.
5.three recurrence formulae for solving increment dynamic equilibrium equation of a non-linear structure are derived by using the third order spline function as piecewise trial functions in discrete regions of time according to weighted residual method,namely:the recurrence formula of sPline function subdomain method,that of spline function Galerkin subdomain method,and that of spline function least square subdomain method.
6.The recurrence formula, which satisfies the necessary linking condition of the matrix algebra method for conformation statistics, of the statistical weight matrices of the mth-order interaction approximation for linear polymer chains is derived.
7.Conclusion There are several sp ecial patterns of local NPC tumor recurrence after radiation therapy in the pres ence of normal nasopharyngeal mucosa. MR imaging is the method of choice to depi ct the location and extent of NPC tumor recurrence.
8.When comparing them with the real recurrence intervals of paleoearthquakes,we found that they are quite coincidence,showing that the suggested calculating method can be used to estimate the recurrence interval of earthquakes in active fault zone as well as the seismic risk evaluation.
9.This paper applies the recurrence neural network with deviation error units to forecast the parameters of adjoining rock,the result shows that this method is more convenient than the back analysis method,and also has higher precision and quicker speed than the normal BP network. ?
10.Conclusion Amniotic membrane transplantation combining opertation is an effective method to recurrent pterygium, and the recurrence rate is low.
