    This paper studies a preventive repair policy with two parameters (L,N) for failure waiting time.It is  assumed that when the system fails,it will be replaced in the next preventive repair time rather than at once,and so there will be a failure waiting between failure time and the replaced time.By geometric process,the explicit expression of the average cost rate is derived.Moreover,an appropriate numerical example is given and the optimal (L,N)* policy is derived which makes the average cost rate minimized.

    This paper presents a design of a new reliability calculation method based on uniform test,which organically combines artificial intelligence network.Artificial neural networks abandons the finite element method (FEM) and applies this method,because  the new law can greatly reduce the amount of computation.First,according to the distribution of the random variable,limited samples are extracted by uniform test,which are taken as for the input parameters finite element analysis.Secondly,based on the finite element analysis results,the limited training samples are used to  construct the optimal artificial neural network.Optimal artificial neural network generalization ability is applied to obtain a valid response,and then the reliability index of the structural system is calculated.Finally,this calculation method provides a new attempt  for reliability analysis in the actual testing of complex systems,which is proved to be  practical and effective.

    Because of the novel structure,the imaginary-part photonic crystal (IPPC) has strongly frequency-dependent character and some special optical properties.However,the dispersion relation of doped medium of imaginary-part photonic crystal has not been studied clearly,so that it would be an obstacle for wide investigation and application of IPPC.The authors employ linear forced oscillator model and effective medium theory to build up the dispersion model of doped medium of IPPC.The model can be used to more than one kind of doped agent.Finally,the authors compare the simulation dispersion curve from the model with that from experiment and find that they match well.So the dispersion model which the authors  build up is available,and it can give some help to get further investigation of IPPC optical properties.

    The adsorption behaviors of H2 at the positions of top,bridge,HCP,and FCC on the Ni(111) surface are compared and the respetive vertical distanees between the atom H and the atomic layer Ni are studied.The adsorption behavior at HCP and FCC is stable,while that at bridge adsorption position is not very stable,which is easy to shift to HCP bit adsorption.The adsorption energy at the four different positions was calculatedand obtained as:Ead-top=－11.622 kJ·mol-1，Ead-bridge=－12.036 kJ·mol-1，Ead-hcp=－12.047 kJ·mol-1，Ead-fcc=－12.078 kJ·mol-1.The results indicate that four kinds of adsorption of H2 on surface Ni(111) belong to  chemical adsorption.The adsorption behavior of H2 on surface Pt(111),Rh(111) and Rh(111) need further research.
