Abstract: In this paper we defined regidly the microscopic hole existing in molten salt and established the embedding method for locating the hole and calculating the size of the hole. To describe the statistical distribution of the microscopic holes better we introduce the RDF of the microscopic hole. In molten 900 K LiCl we finded that there were about 20 microscopic holes with the radius larger than 0.10 nm, the largest is 0.18 nm. The RDF of the microscopic holes shewed us that both g_(h-Li~+) (r) and g_(h-Cl~-)(r) have two peaks. The maximal values of the two peaks are about 0.5. The coordinated number of Li~+ ion with microscopic hole is about one and that of Cl~- ion is about 1.5. Using this method we can study the distributional character of different radius of the microscopic holes.
