The results show that the effect of Li is to increase the rate of hardening, however, the addition of lithium does not progressively change age hardening and precipitation process of Al--Cu--Mg--Ag alloys with low Cu/Mg ratio, and significant age hardening response only occurs with the addition of 2.0\%Li.

结果表明，在Al--4.0Mg--1.5Cu--0.4Ag合金中添加锂，可以加速合金的时效进程，但其时效硬化效果并不能简单地随着含锂量的增加而逐步加强，只有当锂含量达到2.0\%时，才表现出显著的时效硬化与强化效果。

What you owe to Milton is not any knowledge, of which a million separate items are still but a million of advancing steps on the same earthly level; what you owe is power-that is, exercise and expansion to your own latent capacity of sympathy with the infinite, where every pulse and each separate influx is a step upwards, a step ascending as upon a Jacob's ladder from earth to mysterious altitudes above the earth.

弥尔顿④给予我们的并不是什么知识，即使有一百万条知识，人类因此迈开百万步，也始终是彳亍在尘世的地面上；他给予我们的是力量，即是说，用你潜在的感应力，向着广袤无垠的世界拓展，扩张，每一记脉动，每一次喷薄，都是上升一步，好似缘着雅各的天梯⑤，从尘世的地面逐步攀上神秘的苍穹。
