摘要： By taking the energy conservation and angular momentum conservation into account, the characteristics of the quantum-tunnelling radiation of Einstein--Maxwell--Dilaton--Axion black hole are studied and the result shows that the tunnelling rate of such a black hole is relevant to Bekenstein--Hawking entropy and that the obtained radiation spectrum is not pure thermal.
