Often in speaking a foreign language we seek in vain for a precise equivalent for some native word or idiom, and find that there is not any definite equivalent, and that we must content ourselves with a vague periphrasis?

薄保？7］文中所说的"a vague periphrasis"，是一种模糊的拐弯抹角的说法，即虚化的说法，这种虚化手法可能会冲淡原文的形象色彩，也就使得翻译成为一种令人遗憾的艺术。

Afterward Waldhausen ([7]) showed that this topological hypothesis was true. Besides, Stallings ([11]) gave another conjecture that was equivalent to Poincare"s Conjecture. Thus we know both conjectures made respec- tively by Traub and Stallings are equivalent to Poincare"s Conjecture.

另外Stallings([11])又提出了另一个代数的猜想并同时证明也证明了这个猜想与庞加莱猜想是等价的，由此可知Traub所给的猜想与Stallings的猜想都与庞加莱猜想是等价的，从而这两个代数的猜想也是等价的。
