Using the relations between Hermite and Laguerre-Gaussian modes and expanding the window function of two-dimensional rectangular hard-edged apertures into a finite sum of complex Gaussian functions, the propagation of complex- argument Laguerre-Gaussian beams through a paraxial optical ABCD system with a rectangular hard-edged aperture is studied. An analytical propagation equation is derived and used to study the diffraction at the rectangular hard-edged aperture and the focusing properties of complex-argument LG beams.

The fracture reasons of high strength PC steel wire are analyzed, it's considered that center segregation, central cavitation, poriness and inclusion are the metallurgical reasons which lead to the facture of PC steel wire and in the rolling process, differential coping quality, microcrack caused by surface defect, abnormal microstructure caused by burnt and improper cooling velocity, the ears on the head of the wire, overlapping of the wire rod itself are the main reasons which lead to the facture of PC steel wire. At the same time, inappropriate pickling, differential phosphorization quality, the bad heat treatment quality, the generation of crack in the improper drawing and transverse crack caused by abnormal laying of the drawing die are also the reasons of the cracking of PC wire.

METHODS: Bone marrow was sterilely separated from human. After heparinization, human BMSCs were harvested using density gradient centrifugation and adherence method. At the fifth passage, BMSCs at 1×108/L were incubated in the 6-well plate and divided into 2 groups. BMSCs in the edaravone group were 50% confluent and incubated in L-DMEM containing basic fibroblast growth factor and fetal bovine serum for 24 hours. After washing in PBS, these BMSCs were incubated in serum-free L-DMEM containing 20 mg/L edaravone for 24 hours. BMSCs in the blank control group were incubated in L-DMEM, supplemented with 10% fetal bovine serum.
