论文摘要
在本文中,获得了用于描述具有辐射的物理系统的新方程。可以在血浆物理学,加速器物理(同步辐射)和天体物理学(引力波)中找到此类系统的示例。新方程是基于第三个vlasov方程来编写的,用于运动量的概率密度分布函数:坐标,速度和加速度。构建的新的弗拉索夫psi-方程使得可以描述自然耗散系统,而不是第二弗拉索夫方程的现象学修改,并在数值模拟中构建保守的差异方案。
A new equation for describing physical systems with radiation is obtained in this paper. Examples of such systems can be found in plasma physics, accelerator physics (synchrotron radiation) and astrophysics (gravitational waves). The new equation is written on the basis of the third Vlasov equation for the probability density distribution function of kinematic quantities: coordinates, velocities and accelerations. The constructed new Vlasov PSI - equation makes it possible to describe naturally dissipation systems instead of phenomenological modifications of the second Vlasov equation, and to construct conservative difference schemes in numerical simulation.
