论文部分内容阅读
一九八五年一月出版的高中生物课本(甲种本),对旧本中许多失误已作了订正,但还存在一些疏忽之处,现提出以供将来修订时之参考。一、第10页糖的通式Cn(H_2O)_m 教材的提法是:“糖分子中的氢原子和氧原子数之比是2:1。糖类的分子式可以用通式Cn(H_2O)_m来表示(n和m可以相同也可以不同)。
A high school biology textbook (Type A) published in January 1985 has been revised to cover many of the mistakes of the old version. However, there are some omissions to be made for reference in future revision. The general formula for sugar Cn (H 2 O) _m is that "the ratio of the number of hydrogen atoms to the number of oxygen atoms in a sugar molecule is 2: 1. The formula for a sugar can be expressed by the formula Cn (H 2 O) _m to indicate (n and m can be the same or different).
