The term "다이어프램" (Barrier) refers to a physical structure that separates two areas, often used in various engineering and architectural applications. It can serve to control the flow of air, water, or sound, providing a barrier that enhances safety and efficiency in different environments. In the context of mechanical engineering, a diaphragm can also refer to a flexible membrane that responds to pressure changes. This type of barrier is commonly found in devices like pumps and valves, where it helps regulate the movement of fluids by expanding or contracting in response to pressure variations.
