在目前的基本粒子理论中，通常从量子化场出发，量子化场相当于无限数量的一类基本粒子的集合。应该量子化的场有时是经典理论中众所周知的场，比如电磁场，但它有时在经典理论中没有直接的对应物，比如电子场，在量子力学中首先出现的是波函数或概率振幅。迄今为止，人们一直认为相对论量子力学最伟大的成就之一是，物质粒子和力场这两件事在经典理论中是完全不同的
In the present theory of elementary particles, it is usual to start from the quantized field, which is equivalent to the assembly of indefinite number of one sort of elementary particles. The field which should be quantized is sometimes the one wellknown in classical theory as in the case of the electromagnetic field, but it nay have sometimes no direct counterpart in classical theory as in the case of the electron field, which appears first in quantum mechanics as the wave function or the probability amplitude. Hitherto it has been regarded as one of the greatest success of relativistic quantum mechanics that the two things, ie the material particle and the field of force, which had been entirely different from each other in classical theory
