摘要：

Photographs show distinct differences between positive streamers in air or in a nitrogen-oxygen mixture (0.2% O-2). The streamers in the mixture branch more frequently, but the branches also extinguish more easily. Probably related to that, the streamers in the mixture propagate more in a zigzag manner, whereas they are straighter in air. Furthermore, streamers in the mixture can become longer; they are thinner and more intense.
