According to the causes,the surface defects can be divided into blister containing non-metallic inclusion,blister without non-metallic inclusion and “raindrop”,“gills”,“mountained”.
By means of the Laika automatic analysis software,non-metallic inclusion can be tested accurately and quickly data treatment and measurement by statistical method.
Mineral exploration made important progress in .coal, uranium, iron, gold, silver, copper, nickel, zinc, lead, antimony, tungsten, molybdenum, vanadium, kainite and characteristic non-metal.
Where non-metal molecules are typically held together by the attraction between a nucleus and a set number of electrons, metal nuclei are surrounded by a sea of shared electrons.
Different batteries use different combinations of metals, and sometimes non-metals like graphite, but the basic idea is to use a pair of chemical reactions to generate a stream of electrons.
