论文摘要
宇宙学中粒子创造的问题是关于粒子数量是无限还是有限的，对于弗里德曼扩展宇宙的标量和纺纱粒子。结果表明，如果一个人在标量粒子中提出特殊术语，则结果总是有限的。进行了粒子创造效果的数值估计。讨论了超重力粒子在宇宙学中的作用。
The problem of particle creation in cosmology concerning whether the results for the number of particles are infinite or finite is discussed for scalar and spinor particles in Friedmann expanding Universe. It is shown that the results are always finite if one puts in case of scalar particles creation a special term into the Lagrangian. Numerical estimates of the effect of particle creation are made. The role of creation of superheavy particles in cosmology is discussed.
