要看你所用的引用格式:
APA的除姓外，全都要缩写，如有"Jr", "II"则最後加上
例子如下:
Jones, H. W., Jr., & Lucas, G., II. (1941). My adventures in Alexandretta.
The Journal of Fictional Archeology, 1, 1–19.
MLA的要全写，如有"Jr", "II"则最後加上
例子如下:
King, Martin Luther, Jr. “I Have a Dream.” March on Washington. Lincoln
Memorial: Washington. 28 August 1963. Address.
