pbq怎么记

The radiochemical purity of radioiodinated 7 α-O-IA-DPN is more than 95%, and still greater than 90% kept for 24 h at room temperature. Radiochemical yields is 81%~ 90%, and specific radioactivity is 83.25 PBq/ mol.

研制结果为：碘标记的7αO IA DPN放化纯度大于95%，标记率为81%～90%，比活度高达83.25PBq/mol，室温下放置24h，放化纯度仍大于90%。

The visible absorption spectra of p-benzoquinone ( PBQ) in CS_2 were measured, and a weak absorption band around 507 nm attributed to n-π~ singlet-triplet transition was demonstrated.

测量了对苯醌（p-benzoquinone，PBQ）在CS2中的可见吸收光谱，论证了该实验中发现的507nm带来源于PBQ的n-π单-三态跃迁。

The CIDEP spectrum of p-benzosemiquinone/ ethylene glycol ( PBQ/ EG) system has been obtained experimentally with the time-resolved ESR spectrometer by using 285 nm laser photolysis.

在285nm紫外激光辐照下，用时间分辨电子自旋共振（TRESR）波谱仪研究了对苯醌/乙二醇（PBQ/EG）体系，得到了发射的苯半醌中性自由基PBQH.和乙二醇碳自由基R。
