In this study, the methodology of linear structural rela- tionship model of latent variable has been studied which is the first time in China. Some extended conclusions have been come up to, such as multi-factor congeneric measure model, the reliability of measurable variable and its hy- pothesis test, the relation between standardized solution and unstandardized solution, multidimensional path model with measure errors, and multilevel model of latent vari- able. Some examples have been shown to help apply these results in practice, such as the analyses of the children growth-development data, the bone density data and the health resources data by means of latent variable model. Not only have new explanations for these data been achieved, but also powerful patterns for applying the theoretical methods in medical sciences and other fields.

Improving vertical resolution for density curves is by means of restructuring the response from large and small spacing sondes and borehole effect correction factor and coherence factor are used. Form the principle of GR logging, calculate volumes in investigating areas taken by borehole, formation, up and low shoulder beds, along with distance between center of gravity of the four unit bodies and detector. Based on the above, the weighting function of each unit body to GR signal contributions are established, thus realizing processing of GR logs with high resolution. The resistivity logging model uses "resolution matching" method to improve the resolution of the logs. After the process, PNN model is made to recognize the oil-gas-water bed. Compared with BPNN, the net work is featured swiftness, accuracy and ease of practical application.
