Destruction and many casualties among both the military and civilians became an inevitable consequence. A large amount of people injured were in need of life-saving treatment and a speedy return to duty. Intensive studies of the specific issues of diagnosis and treatment of thermal injury were conducted in the Soviet Union before the war. The first special units for patients with burn injuries were created, and the first specialists received their first clinical experience. The contributions of famous Soviet scientists in the development of the treatment of burns and frostbite in WWⅡ are studied in this article. The structure of thermal injuries among military personnel and the results of their treatment are shown. Treatment, classification and quantity frostbite in the structure of sanitary losses during the WWⅡ are studied in this article.展开更多
Before and after X-irradiation, two photon spectral hole burning experiments in BaF (Cl,Br) : Sm2+ were performed by a 560 nm laser light at liquid nitrogen temperature.

The results show that spectral hole burning of Sm2+ doped fluoride halide mixed crystals are accompanied by photostimulated luminescence process. This process make hole burning efficiency decreased.展开更多
