例句與造句

1. Why do Variable Specific Impulse Magnetoplasma Rocket drives have the ability to get spacecraft around the solar system better than Ion thrusters?
2. The Variable Specific Impulse Magnetoplasma Rocket ( VASIMR ) is an electro-magnetic thruster for spacecraft propulsion and is expected to be tested in 2015.
3. The Variable specific impulse magnetoplasma rocket ( VASIMR ) engine currently in development will theoretically yield 20, 000 " 300, 000 m / s, and a maximum thrust of 5.7 newtons.
4. A variety of low-thrust, high-impulse propulsion that have either been practically used on spacecraft or are planned in for near-term in-space use are Hall effect thrusters and Variable Specific Impulse Magnetoplasma Rockets ( VASIMR ).
5. Instead of relying on chemical reactions like conventional rockets, Chang-Diaz's creation, the Variable Specific Impulse Magnetoplasma Rocket, or Vasimr, uses radio waves to heat the fuel and magnetic fields to direct a stream of ultrahot ionized gases.
6. It's difficult to find variable specific impulse magnetoplasma rocket in a sentence. 用variable specific impulse magnetoplasma rocket造句挺難的
7. The company has been working on Chang D韆z's concept of the Variable Specific Impulse Magnetoplasma Rocket, known by its acronym VASIMR . The VASIMR is intended to achieve several advantages over current chemical rocket designs, including lunar cargo transport, in-space refueling, and ultra-high speeds for distant space missions.
8. For instance, if limited onboard power fed to its engine was the dominant limitation on how much payload a hypothetical spacecraft could shuttle ( such as if intrinsic propellant economic cost was minor from usage of extraterrestrial soil or ice ), ideal exhaust velocity would rather be around 62.75 % of total mission variable specific impulse magnetoplasma rockets ).
