研究生的英文表述通常可以分为两个阶段:
硕士研究生
Master's degree candidate
graduate student for a Master's degree
master's degree student
postgraduate student for a master's degree
博士研究生
Doctoral candidate
doctor-postgraduate
Doctorate postgraduate
doctoral degree student

建议在实际使用中,根据具体的语境选择合适的表述。例如,在学术写作中,使用“Master's degree candidate”或“Doctoral candidate”会更加正式和准确。在日常交流中,“graduate student for a Master's degree”或“doctoral degree”则更为常见和简洁。
