1·As expected, the memory circuit in the brains of older monkeys didn't sustain activity as well as in younger monkeys, even though they still performed accurately at this short time scale.

正如研究者们所料，年老猴子大脑中的记忆回路不像年轻的猴子那样能长时间保持活跃，尽管它们也和年轻的猴子一样在2.5秒钟这样短的时间之内也能保持清晰的记忆。

2·Copper busbar and busbar column should be able to sustain electric stress generated by electric current of three-phase symmetrical short-circuit of 50 kiloampere and above.

铜母线和母线支柱应能承受50千安及以上的三相对称短路电流所产生的电应力。

3·The utility model relates to an electromagnet, which is composed of a yoke iron, an armature iron, a push rod, a pull rod, a starting coil, a sustain coil, a controlling circuit and an end cover.

本实用新型涉及一种电磁铁，有轭铁、衔铁、推杆、拉杆、启动线圈、维持线圈、控制电路和端盖。
