摘　　要：为了克服化学方法分析聚合物粘结炸药（PBX）检测速率慢、效率低、成本高等缺点，采用紫外/可见分光光度计测定PBX传爆药的组分含量。研究并选择了HMX可见光光谱法的显色反应条件，确定测量波长为550 nm，在此波长下，测定浓度为0.0018 mg·mL^-1的HMX溶液吸光度，回收率为98.9%～101.0%。根据此方法计算出HMX在PBX传爆药中的含量为95.47%，略高于化学分析结果（94.99%）。In order to overcome the defects in chemical analysis on determining the content of polyer bonded explosive（PBX） ,such as low testing rate,inefficiency, high-cost and so on, the composition contents of PBX booster explosive were analyzed by UV/Visible spectro-photometric method. The condition of color reaction of HMX was studied and selected in visible spectrum. The measuring wavelength （λ = 550 nm） was also determined,and the absorbance of HMX solution with concentration of 0. 0018 mg · mL^-1 was given at this wavelength ,and the recovery was determined to be 98.9% - 101.0%. The HMX content in PBX booster was calculated based on this method,and the analysis result （95.47%） was slightly higher than that of chemical analysis （94.99%）.
