本文利用Euler变量下粒子数可变的理想流体作用量唯象描述强外场中的粒子产生过程，发现产生机制的共形不变性严格限制了源的类型，且粒子数密度组合可解释为暗物质。
摘要：
采用Euler变量下粒子数可变的理想流体作用量，对强外场中的粒子产生过程进行唯象描述。研究表明，产生机制的共形不变性对可能的源类型施加了严格限制。结果显示，该模型框架下产生机制中与粒子数密度的组合可被解释为暗物质。
英文摘要：
The action of an ideal fluid in Euler variables with a variable number of particles is used for the phenomenological description of the processes of particle creation in strong external fields. It has been demonstrated that the conformal invariance of the creation law imposes quite strict restrictions on the possible types of sources. It is shown that combinations with the particle number density in the creation law can be interpreted as dark matter within the framework of this model.
