“验算”常见的英文表达是 “check the calculation” 或 “verify the calculation”。
check the calculation:强调对计算过程或结果进行核对、检查,看是否存在错误,是比较常用和口语化的表达。例如:After finishing the math problem, he always checks the calculation to make sure it's correct.(做完数学题后,他总是会验算以确保答案正确。)
verify the calculation: “verify” 意思是“核实、查证、证实”, “verify the calculation” 更侧重于通过一定的方法或手段来确认计算的准确性和可靠性,相对更正式一些。例如:The engineer needs to verify the calculation before implementing the design.(工程师在实施设计前需要验算结果。)
