摘要
黑体的热辐射中含有可见光的部分其所占比例随温度而改变本文档主要研究黑体辐射可见光能量占总辐射能量的比率。从普朗克公式入手，通过对普朗克公式进行积分算出能量密度曲线下的面积，再用相同方法计算在频率范围为内的曲线下的面积，两面积的比值就是所求。根据这一思路我们设计程序对黑体辐射中可见光能量占总辐射能量百分比进行计算。根据所写程序计算在不同温度下可见光能量占总能量的百分比，发现可见光能量占总辐射能量的百分比随着温度的升高而增大，当温度达到一定值时可见光能量百分比最大，而后有下降趋势。

Abstract
The visible light part that takes up the proportion change along with the temperature in the blackbody heat radiation. This paper studies that visible light energy take up of the total radiation energy of rate in blackbody radiation. Start with Planck formula and calculate the energy density of the area under the curve by integraling Planck formula.The same method used in the frequency range from for the area under the curve, two area ratio that is seeking. According to this line of thought of our design process we calculate visible light energy take up of the total rate of radiation energy in blackbody radiation. Calculate visible light energy the percentage of the total energy at different temperatures in accordance with written procedures. The discovery obvious visible light energy occupies total energy the percentage to elevate along with the temperature increases. When the temperature achieves certain value,the visible light energy percentage is biggest,then has a downward trend.
Keywords: Black body radiation  Visible light   Energy  Temperature   Percentage
