问题 Braille(盲文) is a code of small, raised dots on paper that can be read by touch. Louis Braille(路易斯·布雷尔), a 15-year-old blind French student, developed a raised dot reading system in 1824 . The idea came to him from the dot code punched on cardboard a French captain used to send messages to his soldiers at night.
选项
答案 盲文是一种在纸上用凸起的小点表示的密码，可以用手触摸进行阅读。1824年，一个15岁的法国学生，路易斯·布雷尔，发明了用凸点表示的一种阅读体系，一个法军队长用米在夜间给他的士兵送情报的那种用纸片打孔的点状密码使他想到这个主意。
