We prove Szeg?'s strong limit theorem for Toeplitz determinants with a symbol
When the insulated powder pass through the metalline pipe,both generate electrites of egualize in magnitude and opposite symbol.Ace- -ording to,this phenomenon,this paper advanced basic principles, experimental apparatus and experimental result in gainingeleetrostatic hight voltage.Experimental result shows voltage of metalline pipe ri- -ses up to 52.8 KV in four seconds,when the organics powder pass th- rough continually a metalline pipe 20 centimetre in Length,5 centime- tre in diameter.Finally,two ...
