positional assembly造句

These techniques include chemical synthesis, self-assembly and positional assembly.
The tip of a scanning probe can also be used to manipulate nanostructures ( a process called positional assembly ).
Bottom-up approaches, in contrast, use the chemical properties of single molecules to cause single-molecule components to self-organize or self-assemble into some useful conformation, or rely on positional assembly.
Bottom-up approaches, in contrast, use the chemical properties of single molecules to cause single-molecule components to ( a ) self-organize or self-assemble into some useful conformation, or ( b ) rely on positional assembly.
While there are sensory advantages present at the macroscale compared to the limited sensorium available at the nanoscale, proposals for positionally controlled nanoscale mechanosynthetic fabrication systems employ dead reckoning of tooltips combined with reliable reaction sequence design to ensure reliable results, hence a limited sensorium is no handicap; similar considerations apply to the positional assembly of small nanoparts.
It's difficult to find positional assembly in a sentence. 用positional assembly造句挺难的

However, Drexler and other researchers have proposed that advanced nanotechnology, although perhaps initially implemented by biomimetic means, ultimately could be based on mechanical engineering principles, namely, a manufacturing technology based on the mechanical functionality of these components ( such as gears, bearings, motors, and structural members ) that would enable programmable, positional assembly to atomic specification.
