variation regularity is not strong and correlation coefficient is only 0.4257. A few samples have an obvious phenomenon of low porosity and high permeability, which is directly connected......
decomposing the inflation pressure sources in metal chains. The results show that international metal price shocks not only affect industrial output in a direct way, but also indirectly affect the growth of output through the increased pressure on industrial inflation and then triggering a tightening of monetary policy implementation. Affected by factors such as the lack of market demand and the price......

) and pulse duration (5 ms) giving the highest Ep (25 J) and PAP (5 kW), as shown in Table 1. The high PAP and Ep used may have caused extreme melting of the base metal resulting in high dilution. Also...; (6) where △T is the freezing range and DL is the diffusion coefficient of the process material. The evolution of columnar dendrite at the solid- liquid......
