cubic packing造句

• This is what the primitive cubic packing density describes.
• If N > > 120, are there regions of face-centered cubic packing, or what?
• :: TOE, the method you used already accounted for packing density, by assuming primitive cubic packing.
• It may be a really poor packing with a packing density of 0.1, not a cubic packing at all.
• The fact that there's a cube in the expression doesn't imply that cubic packing is involved, if that was your confusion.
• For spheres of equal size, the optimal density ( ratio of filled to total space ) is always \ pi / 3 \ sqrt { 2 } ( a result of Thomas Callister Hales ), and is achieved by the face-centered cubic packing.
• Crystals tend to exhibit the hcp structure alone ( random stacking of hexagonally close-packed crystal planes ), in contrast with a mixture of ( rhcp ) and face-centred cubic packing when allowed sufficient time to reach mechanical equilibrium under gravitational forces on Earth.
• Starting with a single point, ? 0, one can stack copies of the lattice ? n to form an ( " n " + 1 )-dimensional lattice, ? " n " + 1, without reducing the minimal distance between points . ? 1 corresponds to the integer lattice, ? 2 is to the hexagonal lattice, and ? 3 is the face-centered cubic packing . showed that the Leech lattice is the unique laminated lattice in 24 dimensions.
