摘　　要：本文首先通过坐标变换得到了新的Kerr-Newman-Kasuya双荷黑洞解形式。然后运用Euler-Lagrange变分原理,在一般坐标系下对Kerr-Newman-Kasuya双荷黑洞的类时和类光测地线方程作了新的统一推导,并利用Parikh-Wilczek建议的半经典隧穿方法,对有质量带电粒子在Kerr-Newman-Kasuya双荷黑洞视界附近的隧穿辐射作了新的研究,通过计算得到其隧穿几率。研究表明Kerr-Newman-Kasuya双荷黑洞这一类转动黑洞的隧穿辐射可以在一般坐标系下进行分析。In this paper,a new Kerr-Newman-Kasuya dyonic black hole solution form is obtained by coordinate transfor-mation.Then,a new unified derivation of the time-like and null geodesic equation of Kerr-Newman-Kasuya dyonic black holes in the general coordinate system is conducted under the Euler-Lagrange variational principle.In addition,a new study is made on the tunneling radiation of a massive charged particle from the event horizon of Kerr-Newman-Kasuya dyonic black holes by the semi-classical tunneling method proposed by Parikh-Wilczek and the tunneling probability is calculated as well.It is shown that the tunneling radiation analysis of Kerr-Newman-Kasuya dyonic black hole is possible in the general coordinate system.
