摘要
质量体包括了物质、物体、质点、粒子等一切有质量的东西或者实在。光子具有质量是导出光速原理的前提。光子是以光速运动的质量体。质量体可以分裂,相应地光子可以分裂。介绍了光子质量的计算公式。光子波长及频率参数是描述光子能量大小的辅助变量,它们本身并没有物理意义。质量体在接收外来光子的同时,自身也在向外发射光子,由此可以导出黑体辐射的概念。从数学的角度来看,普朗克的能量子模型实际上等效于爱因斯坦的光量子能量模型,否则就推导不出黑体辐射公式。介绍了黑体辐射公式的推导过程。推导了广义的黑体辐射公式。黑体辐射公式本质上是无数质量体所具有的能量的累加,如果放在宇宙尺度上来考察,能量趋于无穷大是必然的、正常的,换言之,所谓"紫外灾难"实际上是正确的描述;当然在人类可及的空间尺度和时间尺度上,能量不可能趋于无穷大,在这种前提下,与实验数据较为吻合的黑体辐射公式就是众所周知的普朗克函数。介绍了光子与粒子的碰撞模型。讨论了非碰撞作用力对光子的影响。基于光子与粒子的碰撞模型,解释了各种与光有关的物理现象或者理论模型,包括激光、雷达、玻尔量子假设、康普顿效应/汤姆逊散射、反射/透射现象、衍射/干涉/偏振现象、晶体衍射、金属光电效应、半导体光电效应、pn结的光电效应等。从光子切割电场线的角度,解释了天线的工作原理。
Mass body includes all everything,such as matter,object,particle,granule and other things or reality with mass.The premise of derivation of the principle of light speed is that the photon has mass.Photons are mass bodies moving at light speed.The mass bodies can split,and the photons can split accordingly.The calculation formula of photon mass is introduced.The parameters of wavelength and frequency of photon are auxiliary variables with no physical meanings for describing the magnitude of photon energy.The concept of blackbody radiation can be derived from the fact that a mass body is emitting photons outward while receiving outside photons.From a mathematical point of view,Planck ’s energy quantum model is actually equivalent to Einstein’s light quantum model,otherwise the formula of blackbody radiation cannot be derived.The derivation process of blackbody radiation formula is introduced.The generalized blackbody radiation formula is derived.In essence,blackbody radiation formula is the accumulation of the energy of countless mass bodies.If we put it on the cosmic scale,it is inevitable and normal that the energy tends to infinity, in other words,the so-called "ultraviolet disaster" is actually the correct description.Of course,on the space scale and time scale accessible to human beings, the energy cannot tend to infinity.Under this premise,the blackbody radiation formula which is more consistent with the experimental data is the well-known Planck’s function.The collision model of photons and particles is introduced,and the influence of non collisional forces on photons is discussed.Based on the collision model of photons and particles,various physical phenomena or theoretical models related to light are explained,including laser,radar,Bohr ’s quantum hypothesis,Compton effect and Thomson scattering,reflection/transmission phenomenon,diffraction/interference/polarization phenomenon,crystal diffraction,metal photoelectric effect,semiconductor photoelectric effect,photoelectric effect of pn junction,etc.
