The results showed that the different mass concentration of HPAM's absorbance decreases slightly when the PH value of the buffer solution is 5.0, but its reproducibility is better;In order to make the absorbance become more stable, the reaction time was identified adding proper quantities of bromine water, sodium formate and starch-cadmium iodide reagent to the solution separately; the mass concentration curve of the HPAM was draw, by means of the straight degree of the curves, the coincidence degree of the straight line about the concentration of every sampling point and so on , it shows that the mixer has good mixed effect compared with the standard curve.

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。

The interactions of gels with sodium dodecyl sulfate and cetyltrimethyl ammonium bromide were also studied.

First we will use sea water for breeding, then we will develop and utilize the moderate brine and saturated brine drained after breeding to extract bromine for raw salt solarization.

项目拟在盐碱滩上引入海水，先用海水进行养殖，然后对养殖后排出的中度卤水、饱和卤水进行开发利用，提取溴素，晒制原盐，再将晒盐后排出的苦卤进行回收加工氯化镁、氢氧化镁等化工产品，最终实现海水"零排放"，达到最大限度利用资源，降低生产成本，实现可持续发展。

The audio part should be the very impressive part of the machine, best sounding BR forever.

音频部分应该是令人印象深刻的部分机器，最好的探空溴永远。

Next year will be on coal, ore spodumene, bromamine, tellutide and other energy resources; foudamental acid oil plants of raw materials, tetaining solar parabolic reflector as environmental protection equipment and parts of the implementation of a lower rate of tax on imported tentative; continue to crude oil, wood pulp, ferrolloy, steel billet, part of the assets'protection, such as energy consumption on the environmental impact of large exports tentative tax rate.

明年将对煤炭、锂辉石矿、溴、碲等能源资源类产品，植物酸性油等基础性原材料，槽式太阳能抛物面反射镜等有利于环境保护的设备及零部件实施较低的进口暂定税率；继续对原油、木浆、铁合金、钢坯、部分钢材等资源性、生产能耗高、对环境影响大的产品实施出口暂定税率。
