工业设计缺陷。西班牙的潜艇不放水里不沉。家里的洗衣机,用supper的水位就会漏水,放在其他的水位没事,是什么原因呢?
那位高人请指点,谢谢!
好了,正经的着急呢,是SuperSupper is a name for the evening meal in some dialects of English. While often used interchangeably with "dinner" today, supper was traditionally a separate meal. "Dinner" traditionally had been used to refer to the main and most formal meal of the day, which, from the Middle Ages until the 18th century, was most often the midday meal. When the evening meal became the main meal, it was referred to as "dinner", and the lighter midday meal was called "luncheon".
