如下是一些主要问题:1)文章的行文格式。文章没有按照一般科技论文的表述方式,如1是引言,2是常用方法,其实这都应该是第一部分引言里应该介绍的,引言中应扼要介绍文章的研究背景、目的,意义,采用的主要方法等。还有3是实验装置,4是实验步骤,应该这些都是第二部分,试验材料与方法。2)文章的内容。文章应主要介绍本研究的具体内容,但是本文没有,如3 实验装置部分,这个721分光光度计的原理与论文内容联系不大,根本没必要介绍,标准曲线的研究应该放在最前面等。3)文章的表述不清。如HPAM是何物,文章一直没有介绍,什么曲线的直线度、浓度与直线的重合度、什么加入溴水后的时间,应该是反应时间,总之表述不清! 4)文章的图表。图标绘制的很难看。如图2,应该纵坐标起始点从0.25开始,这样图形就会美观很多,图3又没有纵坐标标注,还多了一个纵坐标等。5)文章的结论。文章的结论中有些严格来说不是结论,而是实验中的现象与操作注意事项。
