摘要:
The present invention relates to a new and simple purification process of phosphorus decasulfide (P4S10), also called phosphorus pentasulfide (P2S5), which is used as thionating agent for the syntheses of various organic compounds, particularly the organic compounds having sulfur heteroatom(s).
摘要:
FCIS based-LEMCS designed in this invention accomplishes both of the above proficiencies of measuring the averaged pulse energy of the Pulsed Type Laser Source and calibrating the Commercial Laser Energy Meters, which are traceably to primary level standards, FCIS based-LEMCS contains an integrating sphere having a novel port and an interior design and a series of mechanical choppers having separate Duty Cycles, each of which is rotated by an electrical motor in FCIS based-LEMCS, used for generating a chopped type laser, called as Chopped Type Laser Source, in order to provide the reference and averaged pulse energy for traceable calibration of Commercial Laser Energy Meters.
