先确认YT24缺失信息 Confirm missing YT24 information first
YT24现有公开信息不足以和YT27做完整数值对比。应先取得当前YT24版本的正式参数与配套资料，未知项保持未知。 Available YT24 information is insufficient for a complete numerical comparison with YT27. Obtain formal data and accessories for the current version; leave unknown items unconfirmed.
再比较共同工况 Then compare against the same requirements
把目标孔径、孔深、岩性、作业方向、现场空间、管路和同时开机数量写成同一张需求表，再分别判断两款是否进入候选范围。 Use one requirement sheet for diameter, depth, rock, direction, space, hoses and simultaneous drill count to assess both models.
不做未经实测的优劣结论 Avoid untested superiority claims
没有同条件测试或正式技术资料时，不发布谁更省气、更耐用或效率更高的绝对结论。 Without same-condition tests or formal documentation, do not claim one model uses less air, lasts longer or drills faster.
