本文回顾了先行研究中有关「~ていく」的论述,发现迄今为止的研究很少涉及表示心理回归的＂~ていく＂的用法,并通过问卷调查发现,日语学习者对此用法的＂~ていく＂也较为陌生。本文从基本特征、使用条件和内外意识三方面对表示心理回归的＂~ていく＂进行论述,认为动作主体以外人身份身处临时环境、动作主体在临时环境里实施某一动作、动作主体有自己的应属环境这三点是表示心理回归的＂~ていく＂的必要条件,满足了这三点的＂~ていく＂使表达更具临场感,而不满足这三点的＂~ていく＂则往往为误用。

Construction of proton transport channels in metal-organic frameworks(MOFs)with simple synthesis processes,high proton conductivities and good performance stabilities has been of great interest for proton exchange membrane fuel cell(PEMFC).Herein,we mimic the proton transport behavior of amino acid residues in bacteriorhodopsin,select UiO-66-COOH as the host,glycine and aspartic acid as the functional guest molecules,and then functionalize the MOF framework with amino acids to obtain biomimetic proton transport *** strategy endows UiO-66-COOH-Asp a high proton conductivity of 1.19×10^(-2)S/cm at 70℃and 98%RH,excellent cycle stability of performances and performance durability,which can be comparable to the reported MOFs-based proton ***,the proton conduction mechanism in UiO-66-COOH-Asp is elaborated in detail due to its visual structure,which is also one of the advantages of adopting MOFs as research platform,making it possible to optimize the structure-activity relationship of advanced ***,this strategy has clear objectives and simple synthesis,which has made certain contributions to both theoretical research and future industrial production of proton conductors.
