Constructing Randomizer in Fractal Theory Applications

WEN Wo-gen(Chinese Academy of Surveying and Mapping,Beijing 100039,China)  
The randomizer of C-language work generally in 16 bits. It can not meet the practical needs in 32 bits or higher environment. This paper put forward two methods of constructing randomizer in the Fractal applications: (1) The randomizer satisfing the Gauss normal distribution N(0,1) is constructed basing on central limit theorem of the probability theory; (2) The random sequence is created basing on the Chaos principle. There is not only randomness inside the random sequence but also in random sequence itself. Last part introduces an example of application result.
