By synthetically analysizing the physical and chemical properties of all components and particle size, the content of F2641 in the JOB-iC is determined by gravimetric analysis after F2641 is seperated from HMX,TATB and PNP through ? alkali reflux. Determination conditions is set as follows the sample is boilingly refluxed for six hour in a constant temperature bath after adding lOOm! 8.0 ?? 0.1% NaOH. The solvent DMF saturated by TATB is used for extracting HMX,F21 and PNP from the sample and TATB is seperated by crucible filter G4. The mass precent of TATB is determined by extraction fractionation. The mass percent of PNP is measured by multiwavlength linear regression ultraviolet spectrophotometry. The testing conditions are set as follows:multiwavlength constitution: X=267nxn, 275nm, 283nm, 29mm, 299nm,the application scope of the Lambert-Beer law: the concentration of PNP is O.005?0.O25mgIml, the concentration of HMX is 0.060.3Omg/ml,absorption coefficents of PNP and HMX are solved by the slope of linear regression curve of absorbency- concentration of standard solution of PNP and HMIX for measuring wavelengthes,on the basis of the Lanibert-Beer law and absorbancy additivity principle, the slope of linear regression curve of A/E(1) and E1 of PNP and HMX solution is regarded as the concentration of PNP in the solution.

根据传爆药中各组分的物理、化学性质及主体炸药的粒度大小，进行综合分析，确定了采用碱回流重量法测定JOB-1C 中F_(2641)的含量，测定条件：加入100ml浓度为8.0±0.1％的氢氧化钠，在恒温水浴中煮沸回流6h；采用溶剂萃取法测定JOB-1C中TATB的含量，选择TATB饱和的二甲基甲酰胺为萃取溶剂，用G4坩埚式过虑器进行萃取分离；采用多波长线性回归紫外分光光度法测定JOB-1C中PNP的含量，通过实验确定了多波长组合：λ=267nm，275nm，283nm，291nm，299nm；朗波—比耳定律的适用范围为PNP浓度：0.005～0.025mg/ml，HMX浓度：0.06～0.30mg/ml；在测定波长下，对PNP、HMX标准溶液的吸光度—浓度进行线性回归，由回归曲线的斜率得出PNP、HMX的吸收系数；根据朗波—比耳定律和吸光度加和性原理，在测定波长下，对PNP、HMX 两组分混合溶液A_i/E_HMX(i与E_PNP(i/E_HMX(i进行线性回归，回归曲线的斜率即为混合溶液中PNP的浓度。

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。
