物体粒子特性与波动特性的关系与转换——质量、动能和作用力关于时空的二阶偏微分方程的相对论研究
The Relation and Transformation between Particle Characteristics and Wave Characteristics of Objects—Relativistic Study of the Second-Order Partial Differential Equation of Mass, Kinetic Energy and Force to Space-Time

由经典力学推导出的质量、动能和作用力关于时空的二阶偏微分方程， ，即MEF方程，反映了质量、动能和作用力在时空中的瞬间效应，体现了物体的粒子特性。当考虑相对论效应时，实物粒子和光子都有对应的相对论MEF方程。实物粒子的相对论MEF方程可分解为粒子特性MEF方程和波动特性MEF方程，体现了实物粒子的波粒二象性。如果可以达到光速，实物粒子的相对论MEF方程将完全转化为光子相对论MEF方程，实物粒子转化为光子。当实物粒子在接近和达到光速时，其运动质量应采用含有光子运动质量的公式进行计算。当实物粒子被加速时，其有可能被加速到光速并转化为光子。
The second-order partial differential equation of mass, kinetic energy and force with respect to time-space derived from classical mechanics, , namely MEF equation, shows the instantaneous effects of mass, kinetic energy and force in time-space and reflects the particle characteristics of objects. When relativistic effect is considered, both physical particle and photon have corresponding relativistic MEF equations. The physical particle’s relativistic MEF equation can be decomposed into particle-characteristic and wave-characteristic MEF equations, reflecting the wave-particle duality. If it reaches the speed of light, the physical particle’s relativistic MEF equation can be completely transformed into the relativistic MEF equation for a photon, and the physical particle will be transformed into a photon. When it nears or reaches the speed of light, physical particle’s motion mass should be calculated by the formula containing the motion mass of photons. When a physical particle is accelerated, it is possible to be accelerated to the speed of light and transformed into a photon.
