利用电子束辐照技术降解水溶液中的托拉塞米，通过对降解效果及其影响因素和降解产物的研究，系统地探讨了托拉塞米的辐照降解特性和可能的降解途径。研究显示，电子束辐照可以有效地降解托拉塞米。实验结果表明：活性粒子•OH在降解过程中起主要作用；托拉塞米的初始浓度、吸收剂量、溶液pH、H₂O₂和无机阴离子（CO32-、NO2-、SO32-和SO42-）等环境因素也会对托拉塞米的辐照效果产生影响。托拉塞米的初始浓度越低，辐照吸收剂量越高，溶液pH值越低，降解效率越高；SO42-和低浓度的H₂O₂会促进托拉塞米的降解，而CO32-、NO2-、SO32-和高浓度的H₂O₂会抑制托拉塞米的降解。最后采用高效液相色谱-四级杆飞行时间质谱联用（HPLC-QTOF）检测出托拉塞米的辐照降解产物，并推测出相应的降解途径。

A simple capillary-based extrinsic Fabry–Perot structure is presented and fabricated, using the manual welding method with the strain sensing characteristics investigated in detail. Strain sensitivities of 4.2, 2.8, and 2.4 pm/με are obtained experimentally with the interferometer length around 50 μm and the inner diameter of 75, 50, and 25 μm, respectively. The underlying physics of the strain sensitivity of this device is negatively correlated with the interferometer length and positively correlated with the capillary inner diameter, which provides two simple parameters to tailor the strain sensitivity.
