To understand the Gaussian heat source model, we need to know what gaussian curve is. Generally speaking, if the surface temperature of a circle is the same, then its heat source model is equivalent to the temperature of a circle with the same diameter. The qualitative understanding of Gaussian heat source model is that the temperature is in a circle with the same diameter, and the center is high and the outer edge is low. Quantitatively understand that in a circle with the same diameter, the temperature is distributed according to gaussian curve.

Gaussian distribution is normal distribution, and Gaussian model is almost zhi rate density function of Du's various states. It is considered that the probability density function of normal distribution should be known. Gaussian model is to establish the probability density function of its dependent variable x, which can quickly derive the probability value at a certain moment.
