"固定的雕刻物" can be translated into English as "fixed sculpture" or "permanent sculpture", depending on the context and the intended emphasis.
"Fixed sculpture" emphasizes that the sculpture is immovable or permanently installed in a particular location.
"Permanent sculpture" highlights the long-lasting or enduring nature of the sculpture, suggesting that it is intended to remain in place indefinitely.
Both expressions are commonly used in art and architectural contexts to describe sculptures that are not intended to be moved or relocated.
