把化学奖物理奖说成文学奖，把镭说成铀，可以是口误。但X光机是什么口误？

But at the start of the war, X-ray machines were still found only in city hospitals, far from the battlefields where wounded troops were being treated. Curie’s solution was to invent the first “radiological car” – a vehicle containing an X-ray machine and photographic darkroom equipment – which could be driven right up to the battlefield where army surgeons could use X-rays to guide their surgeries.

X光机这个其实是对的。之前的X光机不能移动，居里夫人发明的移动式X光机可以装在车里。
