    摘要:

    众所周知,造成太阳辐射和活动的动力来自太阳内部,而其内部性质复杂多变,因此太阳内部的压强分布对于研究太阳内部结构、内部物质的状态及运动情况就显得十分重要。为了得出太阳内部的压强分布,通过基于参数的无量纲化,假定太阳的密度是球对称性分布,考虑边界条件,利用“流体静力学方程”研究了密度和压强的分布函数,最终拟合出太阳的密度和压强的分布曲线。结果表明:曲线给出的太阳的中心密度和太阳的中心压强,分别为1.6240×105 kg·m-3和3.4606×1016 Pa。可见这与目前教科书中所列出的数值基本一致,这对研究太阳的内部性质来说具有一定的意义,也为研究其他恒星内部压强提供了一些分析思路和方法。

    Abstract:

    As is known to all, The force that causes solar radiation and solar activity comes from the Sun's Interior, in addition, its internal properties are complex and changeable, the pressure distribution inside the sun is therefore critical to study the state,the motion of internal material and the internal structure of the Sun. In order to get the distribution of the pressure inside the sun, the "fluid statics equation" is used to study the distribution function of the density and pressure of the sun by dimensionless parameter-based, assuming that the density of the sun is spherical symmetry distribution, considering the boundary conditions, and finally fitting the distribution curve of the density and pressure of the sun. The results show that the central density and the pressure in the Sun's core, which are respectively 1.6240×105 kg·m-3 and 3.4606×1016 Pa?respectively. It can be seen that this is basically consistent with the current accepted values listed in the textbooks, which is of great significance for the study of the internal properties of the sun and provides new ideas and methods for the study of the internal pressures of other stars.
