The integrated circuit (IC) industry has high requirements for vibration prevention in its production processes. The micro-vibration prevention structures installed above the buildings used in the preliminary stages of IC manufacturing can be of either reinforced concrete or steel construction. Which of the following statements is correct? A. Steel structures are more expensive than reinforced concrete structures, but steel structures can effectively reduce the impact of vibrations. B. Steel structures are more expensive than reinforced concrete structures, and reinforced concrete structures can effectively reduce the impact of vibrations. C. Reinforced concrete structures are more expensive than steel structures, but steel structures can effectively reduce the impact of vibrations. D. Reinforced concrete structures are more expensive than steel structures, and reinforced concrete structures can effectively reduce the impact of vibrations. Answer: B
The integrated circuit (IC) industry has high requirements for vibration suppression in its production processes. The micro-vibration suppression structures installed above the facilities used in the early stages of IC manufacturing can be of either reinforced concrete or steel construction. Which of the following statements is correct? ( B) A. Steel structures are more expensive than reinforced concrete structures, but steel structures can effectively reduce the impact of vibrations. B. Steel structures are more expensive than reinforced concrete structures, and reinforced concrete structures can effectively reduce the impact of vibrations. C. Reinforced concrete structures are more expensive than steel structures, but steel structures can effectively reduce the impact of vibrations. D. Reinforced concrete structures are more expensive than steel structures, and reinforced concrete structures can effectively reduce the impact of vibrations
B. Steel structures are more expensive than reinforced concrete structures, while reinforced concrete structures can effectively reduce the impact of vibrations
This type of question should not be asked again; considering the single-story structure of the factory building at present, it is exactly the opposite of B.
