票据关系与票据原因关系是票据法上非常重要的两个概念,对二者之间关系的认识影响着整个票据法律制度的构建.票据关系的无因性体现了二者之间的分离关系;票据关系无因性的例外又体现了二者之间的牵连,这种既分离又联系的关系在我国票据法实践当中频繁发生。 The relationship between the notes and the notes is the two concepts that are very important in the Notes Act.The recognition of the relationship between the two affects the construction of the legal system of the entire note.The non-consensuality of the notes reflects the separation between the two. The excuse of non-consensual relationship of notes also reflects the implicatedness between the two. This kind of relationship, which is both separated and connected, has occurred frequently in the practice of negotiable instruments in our country.
