The possible reaction mechanism was proposed. The critical temperature of thermal explo-sion was calculated. The influence of the title compound on the combustion characteristic of composite modified double base propellant containing RDX has been explored with the strand burner. The results show that the kinetic model function in differential form, apparent activation energy Ea and pre-exponential factor A of the major exo-thermic decomposition reaction are 1-a, 207.98 kJmol-1 and 1015.64 s-1, respectively. The critical temperature of thermal explosion of the compound is 312.87 ℃. The kinetic equation of the major exothermic decomposition process of the title compound at 0.1 MPa could be expressed as: ()416.422.502?d101 edTTaa-10=-. As an auxiliary catalyst, the title compound can help the main catalyst lead salt of 4-hydroxy-3,5-dinitropyridine oxide to en-hance the burning rate and reduce the pressure exponent of RDX-CMDB propellant.展开更多

Direct communication with medical doctors is necessary to identify specific requests and unmet needs. Information on innovative, new or renewed techniques is necessary to design medical devices for introduction into clinical application and finally to become established after positive clinical trials as well as medical approval. The long-term endurance in developing light based innovative clinical concepts and devices are described based on the Munich experience. Fluorescence technologies for laboratory medicine to improve non- invasive diagnosis or for online monitoring are described according with new approaches in improving photody- namic therapeutic aspects related to immunology. Regard- ing clinically related thermal laser applications, the introduction of new laser wavelengths and laser parameters showed potential in the treatment of varicose veins as well as in lithotripsy. Such directly linked research and development are possible when researchers and medical doctors perform their daily work in immediate vicinity, thus have the possibility to share their ideas in meetings by day.展开更多
