And then the LM method and specific steps of evaluation for the system availability and storage period are given.

Application of LM arithmetic in groundwater regime forecast;

Accordingly, this paper comes up with acoustic porosity for predicting reservoir by LM arithmetic based on neutral network, whose main procedures comprise: selection and pre-transaction of samples, design of network structure, network training of LM arithmetic based on Matlab neutral network toolbox programming and prediction of acoustic porosity.

Real time identification for parameter of wide V-shaped free bending on based LM algorithm;

Application of LM algorithm in data fusion disposal of sensor;

The static time and temperature’s drift of the quartzose flexible accelerometer in SINS was studied through theory and experiments,and a LM algorithm’s BP network was developed to compensate the drift.
