Abstract: This paper takes the large prime numbers as a module, the primitive roots of the module will be multiplicator and introduced concepts of Bands and Quasi-Symmetrical Distribution. Based on the distribution graphs of the pseudorandom points are generated by the multiplication congruential method gives nine distribution theorems and a deduction. Therefore, this paper will creat conditions for studies in connection with the pseudorandom points and get more simple and pricise deviation expression of the pseudorandom numbers.
