• The flames of ethylene and oxygen mixtures (initial pressure, 50–500 mmHg, and ethylene content, 20–40%) were studied, especially for the transition to detonation from deflagration. The flames may roughly be divided into four groups: <B>A</B>, a flame without any shock wave generation; <B>B</B>, a flame with a shock wave generation; <B>C</B>, a flame with many shock waves and much turbulence of the flame, and finally <B>D</B>, the detonation produced by the collision of a flame and a reflected shock wave at the bottom of the tube. The flame transit to detonation from deflagration is a linear relation between the velocities of the flames at the point of detonation and DID, or the distance from the point of ignition to the detonation for all the sorts of flames given above, in spite of several apparent differences.
