摘要
针对空气压缩引火仪实验操作中出现硝化棉不着火、燃烧时间短等问题,设计了利用温变油墨代替硝化棉演示对空气做功使空气的内能增加的实验,改进后的实验现象明显.
Aiming at the problems,such as no ignition of the nitro-cotton,short burning time,the air-compression ignition experiment was improved.In the improved experiment,the temperature sensitive ink was used to replace the nitro-cotton to demonstrate the phenomena that doing work can increase the inner energy of the air.The effect was obvious.
