1. Some devices support zero length  lines, while others do not. 2. The Soviet and Western trials with zero length  launch were also related. 3. Most zero length  launch experiments took place in the 1950s, during the Cold War. 4. This calculation shows that the Cantor set cannot contain any interval of non-zero length . 5. A zero length  frame is included in the specification for'null'and erasure frames. 6. A ideal slit is of zero length  so the walls i am talking about are tha walls facing the source. 7. The " border " with San Juan County, Colorado, is, however, only a point of zero length . 8. Since the parallels shrink to zero length  as they approach the pole they have to be stretched by larger and larger amounts. 9. A single point is drawn by entering graph mode at the desired coordinate, drawing a zero length  vector to the same coordinate. 10. For polarized light the end of the vector lies on the surface of the sphere, whereas the vector has zero length  for unpolarized light.
