wanghaojie Member HJ Join Date: Nov 2011 Posts: 30 Rep Power: 14	i am wondering can i get real velocity from energy spectrum function (frequency domain), which can have a form like sinusoid function? Can i set temporal difference equal to zero in the autocorrection function? In this way i think i can only get the mean value of u_i square. or is there any other way? Thanks
