Russia and China are both developing long-range missiles that are manoeuvrable and accurate enough to hit large ships at sea.

俄罗斯和中国都在研发远程，这种机动性和精确性足以打击海上大型船只。

Now, as it stands, the robot is slow, simple and not especially manoeuvrable.

现在，就目前而言，机器人速度慢、单，而且机动性不是特别好。

It is the second report in recent months of North Korea testing a weapon that is more manoeuvrable than a conventional ballistic missile.

这是近几个月来有关朝鲜试验这一武器——它比常更具机动性——第二份报告。

These aren't just fancy helicopters - they're  much quieter than your average chopper, multiple rotors make them more manoeuvrable  and safer and because they're electrified, they're cleaner and cheaper to run too.

这些不仅仅是花哨直升机——它们比普通直升机安静得多，多个旋翼使它们更灵活、更安全，而且因为它们是电气化，所以它们更清洁，运行起来也更便宜。
