例句與造句

1. "' ICAN-II "'was a proposed manned interplanetary spacecraft that used the Project Orion design put forth by Stanislaw Ulam in the late 1950s.
2. In future manned interplanetary spacecraft, 10 B has a theoretical role as structural material ( as boron fibers or BN nanotube material ) which would also serve a special role in the radiation shield.
3. Like BN fibers, boron nitride nanotubes show promise for aerospace applications where integration of boron and in particular the light isotope of boron ( 10 B ) into structural materials improves both their strength and their radiation-shielding properties; the improvement is due to strong neutron absorption by 10 B . Such 10 BN materials are of particular theoretical value as composite structural materials in future manned interplanetary spacecraft, where absorption-shielding from cosmic ray spallation neutrons is expected to be a particular asset in light construction materials.
4. It's difficult to find manned interplanetary spacecraft in a sentence. 用manned interplanetary spacecraft造句挺難的
