| Popis: | The sequence of events which occurs in a thin confined film of nitroglycerine, after an explosion is initiated by a condenser spark, has been examined by means of a rotating drum camera. It has been found that in a very thin film (< 0$\cdot $01 mm. thick) the explosion begins as a gentle process which is propagated through the nitroglycerine film at 400 m./sec. After continuing for about 0$\cdot $5 cm. this process is transformed suddenly to a more violent type of explosion which is propagated at 2000 m./sec. The explosion reproduces in miniature several of the well-known effects characteristic of the setting up of the detonation wave in gaseous mixtures. When explosion is initiated in the same manner in a thicker film, the 400 m./sec. type of propagation is not set up immediately but is preceded by a very much faster process ($\not |
