实例分析

1. Example Sentence:

   • Original: The new ceramic coating offers excellent corrosion resistance.
   • Explanation: This sentence demonstrates the use of a common term in materials science (“ceramic coating”) and a phrase to describe its property (“offers excellent corrosion resistance”).

2. Code Example (Python): “`python def material_properties(material, hardness, tensile_strength): if material == “aluminum”:

      return f"{material} has a hardness of {hardness} and a tensile strength of {tensile_strength}."
   

   elif material == “steel”:

      return f"{material} is known for its high strength and durability."
   

   else:

      return "The properties of the material are not specified."
   

# Example usage print(material_properties(“aluminum”, 60, 270)) “`
