We have performed simulating annealing in computer by using Monte Carlo technique to produce a random-network model of amorphous silicon. The structural characteristics of this model is in good agretment with that of real sample.
Its mathematical model is set up and its controllable workspace is analysed on the basis of the principle of vector closure. And then, the feasibility of the chosen analytical method is simulated and verified by adopting Monte Carlo technique for programming in the environment of MATLAB. The results of simulation are the approximately numerical representation of controllable workspace, of which the display accuracy can be increased by increasing the number of points extracted.
The variation of the parameters is modeled by multivariate probability density function proposed by Freeze,and the dynamic characteristics of soil are studied by Monte Carlo technique.
We can determine ineffective water supplying area and the rate of water supply of node by analysing the reliability of system with Monte Carlo Method, find the weak link, and provide technique and countermeasure for damage prediction and aseismic reinforcement.
Secondly,randomicity of solid propellant mechanics properties and loads was all considered,at the same time stochastic analysis of a hollow cylindrical grain with elastic restraint was presented by combining Monte-Carlo technique.
To determine the depth behavior of the forward current and the dosage rate in the irradiated polymer, numerical calculations are made by the Monte Carlo technique.
Computer simulations of the relaxation of nonequilibrium states using the Monte Carlo technique qualitatively describe the kinetics observed in experiments.
The time correlation function and the interference component of the coherent backscattering from a multiple-scattering medium are calculated in the framework of the Monte Carlo technique.
We have performed simulating annealing in computer by using Monte Carlo technique to produce a random-network model of amorphous silicon. The structural characteristics of this model is in good agretment with that of real sample. Its vibrationol densities of states have been calculated with molecular-dynamics method. The relationships between its locaiized vibrational modes and the structural defects have also been discussed.
The transmitting characteristics of high-energy electron beam in Langmuir-Blodgett (LB)film and multilayer films have been studied. The electron trajectories in LB polymethylmethacrylate (PMMA)resists and Si substrate covered with Cr film have beensimulated on computer by applying Monte-Carlo technique .The advantages of LB resists in electron beam exPOsure lithography have been discussed in this paper.
The jointed structure distribution of rock mass is simulated by Monte Carlo method. Based on fracture mechanics, original extension and the stopping of crack of the jointed rock mass is analysed,the extended angle and the extended length of the jointed rock mass by blasting is calculated, and the figure of the jointed rock mass structure after blasting is drawn. It is very important to research into the characteristics of the rock mass after blasting.
