根据 The great advance in rocket theory 40 years ago showed that liquid-fuel rockets were far superior(优越) in every respect to the sky rocket with its weak solid fuel,the only kino of rocket then known可以推测出两种燃料各有优势,用途不同用法不一样,故选C。2.考查对文意的理解。It all ...
Transportability issues: Solid propellants are cast into the motor in the factory, unlike liquid fuel rockets which can be fuelled at the launch pad. This means they have to either be: 1) limited in size to be transportable (as for the Delta and Ariane strap-on motors); 2) cast in seg...
