A software system to estimate the effect of heat presevent for long distance lines based on Larson Miller method and infrared image as well as the databases of operation parameters was established.

To test her method, Dr Miller looked first at the period from 1940 to 1990 (America began making accurate hurricane records in 1940).

In this paper, a method of lattice transformation is introduced to demonstrate the relational expression between Miller indices and interplanar spacing in base-centered monoclinic lattice.
