DESCRIPTION:This paper briefly reviews the engineering development of Model
 ica-based hydraulic system modeling. On this basis\, it reconsiders the is
 sue of reasonable decomposition in component-based hydraulic modeling and 
 discusses the methodological relevance of Xu's method for the development 
 of Modelica hydraulic model libraries. Finegrained component decomposition
  facilitates rapid assembly and reuse\, especially for users without exten
 sive hydraulic modeling expertise. However\, excessive subdivision may als
 o introduce duplicated pressure states\, hidden volumes\, artificial fast 
 time constants\, increased numerical stiffness\, and ambiguous physical se
 mantics. Through order-of-magnitude examples involving pilotoperated relie
 f valves\, pressure compensators in multiway valves\, short manifold passa
 ges\, hydraulic cylinder chambers\, and accumulator groups\, the paper ill
 ustrates that the appropriate component boundary depends on the modeling o
 bjective\, the dominant physical mechanism\, the available parameters\, an
 d the quantities to be validated.
