翻译器翻译的看不懂。这里是原段落For many of the uses to which Phosphor bronze and other deoxidized tin bronzes are put,it is important that the metal have good endurance strength.As heretofore produced,the best grades of deoxidized tin bronze possess endurance strengths substantially less than 35,000 pounds per square inch at 10,000,000 cycles,and less than 30,000 pounds per square inch at 300,000,000 cycles.The ultimate endurance limit of the best commercial Phosphor bronzes heretofore made is probably less than 25,000 pounds per square inch.

这里说的是合金的疲劳强度.
疲劳强度的测定就是反复施加一定的应力,看它什么时候断.所以应力越大,断裂的循环次数越少.你如果查疲劳强度的s-n曲线就可以看出来.当小于某个应力值时,理论上就可以循环无限次不断裂了.
在应力是每平方英寸35000磅时,循环次数远小于10000000次.
在应力是每平方英寸30000磅时,循环次数小于300000000次.
最后的疲劳极限是每平方英寸25000磅,这就是它能保持无限循环不断裂的理论数值.
在1000万转时，锡青铜的耐久强度实质上小雨为35000磅/平方英寸。
这应该是材料学上的东西吧
在1000万转时，每平方英寸会承受35000磅的重量
当转速达到1千万转时，每平方英寸存在3万5千磅的压力
意思为：青铜器在强度上能够承受压力35000磅每平方英寸10,000,000次，或者 30000磅每平方英寸300,000,000次
35000磅每平方英寸10000000周期
