斯德哥尔摩的格罗纳隆德过山车发生事故，就是因为替换零件强度低导致的。 Grona Lund roller coaster accident in Stockholm was caused by weak replacement parts.

瑞典官员透露，去年斯德哥尔摩格罗纳隆德公园发生的过山车事故，造成一人死亡，九人受伤，就是由于替换零件质量不合格造成的。 Swedish officials revealed that a roller coaster accident last year at the Grona Lund park in Stockholm, which killed one and injured nine others, was caused by weak replacement parts. 调查人员发现，该国最古老的游乐园没有对过山车的新部件进行适当的测试，特别是支撑臂，其强度不够。 The investigators found that the country's oldest amusement park did not properly test new parts for a roller coaster, particularly the support arms, which were not sufficiently strong.
