On the base of the single-diameter laser-scanned measuring technology, a double direction laser-scanned measuring system is presented. Which combinate the laser-scanned measuring technology with special optical system. In the system, the collimation semiconductor laser-scanned beam scanning two perpendiculars direct of one plane of the measured workpiece at the same time is made. The beams with the dimension information of two perpendiculars direct are processed by the scanning receive system, the high-speed photoelectric transition and electronic data process. Two measured results of the diametric directs and ellipse tolerance,etc, parameter, of the turning workpiece on the same plane are obtained by non-contact automatic measurement. The problem of non-contact measurement of two perpendiculars direct of one plane of turning workpiece is settled. It processes many peculiarities, such as high speed, high accuracy and non-contact automatic measurement, etc.

Density Functional Theory in connection with accurate LCAO basis sets and norm-conserving pseudopotentials were used to study two issues which are (1) The Selective Functionalization of Single-Walled Carbon Nanotubes with Diazonium Radical and (2) The Molecular Dynamic Simulated IR Spectrum of Adsorbed C3H3 and I on the Ag(111) Surface.For the first, we investigated (1) NO2C6H4 direct addition (2) NO2C6H4N2 dissociative addition reaction on semiconductor (8,0), metallic (9,0)and(5,5) carbon nanotubes.
