In each sentence, select the best choice for a Lewis technical report:
- Drag is caused by the shuttle's high speed through the very
thin atmosphere of space, which results in a force about 1 millionth that
of Earth's gravity (i.e./e.g.,
microgravity).
- The compatibility conditions are controller types of relations;
that is/i.e., deformations
are balanced for finite element discrete analysis.
- This greater range of DLC coating thicknesses led to longer
endurance life. For example/e.g.,
the endurance life of DLC films with a coating thickness of 0.5 mm was
about 20 times greater than that of other films with a 0.05-mm-thick
coating.
- The generalized input files were used to simulate
the cold-test parameters (i.e./e.g.,
frequency-phase dispersion,
Pierce on-axis interaction impedance, and circuit power
attenuation) of two specific circuits.
(All the cold-test parameters are enumerated.)
- Lightweight NiAl intermetallic alloys with superior properties
(e.g./i.e., high melting
temperature and oxidation resistance) are required for the next
generation of high-temperature structural materials.
(The parenthetical phrase mentions only two of the properties that will
be needed.)
- Experiments have demonstrated that if the thermocapillary driving
force (i.e./e.g., the
temperature difference across the free surface)
increases beyond a certain critical value, the flow will change from
being steady to being oscillatory.
(The parenthetical statement explains what the thermocapillary driving
force is.)
- A thin interphase layer between the fiber and matrix enables
matrix cracks to deflect around the fibers
(i.e./e.g., to perform even
when damaged).
(The parenthetical phrase explains what happens when such an interphase
layer is used.)
- Perfluoropolyethers are used to lubricate many space mechanisms
(e.g./i.e., gyroscopes and
filter wheels).
(Examples of such mechanisms are given.)
