It is assumed that a certain reference frame is inertial for a system of moving and interacting bodies called a large system. In the framework of classical continuum mechanics, some necessary and sufficient conditions are obtained for the existence of a reference frame for a subsystem of this large system considered as an independent large system. The motion of such a new reference frame with respect to the old reference frame (with the accuracy up to the Galilean transformations) is specified.

变形机构子系统的惯性参考系

假设某个参考系对于运动和相互作用的物体系统（称为大型系统）是惯性的。在经典连续体力学的框架中，为该大系统的子系统（被视为独立的大系统）的参考系的存在获得了一些必要和充分的条件。指定了这样的新参考框架相对于旧参考框架的运动（精度达到Galilean变换）。
