south,norththis concluded that size distributions of oil-gas deposits obey power-law distrbution quite well and they are fractal distributions within a defined space.

The main characteristics of normal distribution and fractal distribution are introduced.

However,lots of empirical research indicates that it has a fat tail compared with normal distribution and obeys fractal distribution.

The simulated results indicated that using different reconstruction beam to reconstruct digital holographic image,the phase distribution will produce linear or secondary distortion.

The ideal phase distribution of the reference plane can be achieved according to the parameters which are computed by the least square interactive fitting of the corresponding phase of captured specimen grating.

These distribution characters are studied and it is found that the phase distributions can be used as an important criterion for testing cells, distribution because of their relationship.
