Not having equivalent figures I don't know how that compares with USAF norms for an operational squadron.
由于没有相应数字我不知道该如何与美国空军的作战中队比较规范。

However, in existing norms, the mechanical properties of the two are equivalent, therefore, it is essential to further study the mechanical properties of hollow brick masonry and new expansion bolts.
但现行规范将二者的力学性能等同，因此有必要对空心砖砌体和新型膨胀螺栓的力学性能作进一步的研究。

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