Analytical results show that: Anode evaporation rate, which determines mostly the production rate of UFMP, is influenced by the many factors including electric parameters of arc, ambient conditions and material properties et al; Existence and increase of anode ejection can influence the production rate and property of UFMP; It is firstly found and investigated that surface connexity phenomenon of Al anode material. Analyses and calculation show that formation of anode spot and existence of self-magnetic field force play an important part in surface connexity process; Effects of cathode material on prepared UFMP is also experimentally studied and theoretically analysed. It shows that effect of the cathode is inconsiderable under the experimental conditions used in the study. At last, the experimental results found in part one are analysed and discussed in detail.
