研究了Rindler坐标和Kasner坐标下四维Minkowski时空中Dirac场的正频率模函数之间的关系，用Kasner和Rindler坐标下的量子态描述了Minkowski真空态的显式形式，并对解进行了解析延拓.结果得到了Kasner区和Rindler区正频率模函数的统一对应关系，从而导出了真空纠缠。
We study the relations of the positive frequency mode functions of Dirac field in 4-dimensional Minkowski spacetime covered with Rindler and Kasner coordinates, and describe the explicit form of the Minkowski vacuum state with the quantum states in Kasner and Rindler regions, and analytically continue the solutions. As a result, we obtain the correspondence of the positive frequency mode functions in Kasner region and Rindler region in a unified manner which derives vacuum entanglement.
