证明了区间值三角模左连续的充要条件是保递增并，右连续的充要条件是保递减交。

It is proved that a triangular norm is left-continuous if and only if is increasing union-preserving, and is right-continuous if and only if is decreasing intersection-preserving.

构造出了区间值三角模左连续与保任意并不等价的一个严格的反例；

A strict counter-example showing that left-continuity and union-preserving are not equivalent for interval-valued triangular norms is constructed.
