弹簧振子相对于运动惯性系的机械能不守恒——关于“对一道中学生物理竞赛试题答案的商榷”的商榷

The Mechanical Energy Nonconservation of a Spring Oscillator Relative to Moving Inertial Frame——Comment on " Discussion on the answer of a middle school student′s contest question"

验证了一道中学生物理竞赛试题标准答案（弹簧振子相对于运动惯性系的机械能不守恒）的正确性,否定了＂对一道中学生物理竞赛试题答案的商榷＂[1]的质疑,并指出其错误根源.

For a middle school student′s physics contest,the standard answer that the mechanical energy of a spring oscillator relative to moving inertial frame is not conserved is verified.The opposite conclusion given by the paper titled Discussion on the answer of a middle school student′s contest question is dismissed and the error sources are pointed out.
