现行工科中专通用数学教材,是在试用教材的基础上于1984年修订而成的。修订后的教材,内容丰富,系统合理,因而被工科中专学校所广泛采用。这套教材这些年来重印了十多次,对工科中专的数学教学作出了不可磨灭的贡献。但笔者认为,这套教材也存在美中不足的地方,有些章节的表述尚欠严谨就是其中一点。下面仅以第二册第九章第四节《平面和平面的位置关系》为
The current general engineering mathematics textbooks for secondary vocational schools were revised in 1984 on the basis of trial teaching materials. The revised textbooks are rich in content and reasonable in system, so they are widely adopted by technical secondary schools. This set of textbooks has been reprinted more than ten times over the years and has made indelible contributions to mathematics teaching in technical secondary schools. However, the author believes that this set of textbooks also has a fly in the ointment. Some of the chapters are still less rigorous. The following is only the fourth chapter of the second volume, “The positional relations between planes and planes”.
