Key Factors in Determining the Magnitude of Vorticity in Turbulent Plane Wakes
《Chinese Physics Letters》2010年第2期145-148,共4页米建春 R.A.Antonia 
We examine the effects of local turbulence Reynolds number Rλ and inflow conditions on the magnitude of vorticity in plane turbulent wakes. Measurements of the spanwise component (ω3) of the fluctuating vorticity ...

Instability of Solution of Phase Retrieval in Direct Diffraction Phase-Contrast Imaging with Partially Coherent X-Ray Source
《Chinese Physics Letters》2006年第12期3259-3262,共4页郭华 韩申生 
Supported by the Natural Science Foundation of Shanghai under Grant No 04ZR14146 and the National Natural Science Foundation of China under Grant No 60477007.
The theoretical model of direct diffraction phase-contrast imaging with partially coherent x-ray source is expressed by an operator of multiple integral. It is presented that the integral operator is linear. The probl...

Self-Microlensing in Compact Binary Systems
《Chinese Physics Letters》1997年第2期155-157,共3页QIN Bo WU Xiang-ping ZOU Zhen-long 
Supported by the National Natural Science Foundation of China under Grant No.19421004.
The signature of the self-microlensing in compact binaries(white dwarfs,neutron stars and black holes)is a flare with the characteristic time of typically a few minutes.The probability of detecting these microlensing ...

NONLINEAR SCATTERING AND ATTENUATION OF FIRST SOUND IN SUPERFLUID ^(4)He AT HIGH FREQUENCY AND TEMPERATURE NEAR T_(λ)
《Chinese Physics Letters》1988年第6期261-264,共4页CHENG Jianchun WEI Rongjue 
The attenuation coefficient of the impressed first sound due to the scattering of random background of the second sound is calculated.The result shows that this is an important factor which gives rise the attenuation ...
