有关Proposed topic of research 之问题

在国大与南洋理工的申请表中, 均有提到Proposed topic of research (A detailed proposal of at least one page must be attached)以及Significance and aims of proposed research topic (attach a separate sheet if necessary), 不知过来人对此有何建议, 其proposed topic要多detailed, 太专了可能就只能一两个教授的味口, 机会较小, 而且我感觉没有多少可写(我只有本科水平, 无研究经验). 谢了先!
