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，种的机动性和精确性足以打击海上的大型船只。

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.

是近几个月来有关朝鲜试验一武器——它比常规道机动性——的第二份报告。

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.

些不仅仅是花哨的直升机——它们比普通的直升机安静得多，多个旋翼使它们灵活、安全，而且因为它们是电气化的，所以它们清洁，运行起来也便宜。
