The non-infinite divisibility of some skewed distributions generated by the normal kernel,which includes skew normal-normal,skew normal-Cauchy and skew normal-uniform distribution,are investigated.

Using normal distribution to identify oil layer and water layer in Qingxi complex reservoir;

The applied studies of normal distribution and lognormal distribution in the calculation of cefixime s bioequivalence;

Designing of SAS macro program for statistic form of measurement data on normal distribution;

This paper assumes that the volume of the subsurface settlement troughs due to tunneling is equal to the ground loss and the shape of the troughs can still be represented by a Gaussian distribution .

This method uses statistics and adopts gaussian distribution model to analyze the key performance index.

We also assume that the phase error on the aperture led by the random surface error obeys the Gaussian distribution with a zero mean,u.

The results show that the water level variation in freshwater side doesn′t refuse normal school and logarithm normal school, but coincides with normal school better.

Based on the data of average temperature and precipitation of 129 stations of China from 1961 to 2000, this paper uses normal school and Γ distributing simulating probability distributing of average temperature and precipitation separately.

The result is that:in lately 40 years mean of mean daily temperature of apiece season approximately assume high in south and low in north,daytime change is least in summer,geographical diversity of unconformity normal school is evident to four seasons.
