Spectra and influences of Rayleigh backscattering (RB) and stimulated Brillouin scattering (SBS) in the fiber-optic distributed disturbance sensor (FDDS) were investigated. Models of RB, double RB (DRB) and SBS in long fibers were established. By numerical simulation, it was found that optical signal-to-noise ratio is extraordinarily reduced due to SBS and(More)
OBJECTIVE To elucidate the promoting effect of the constituents in plasma after oral administration of Liuwei Dihuangwan on proliferation of rat osteoblast. METHOD To add the constituents in plasma after oral administration of Liuwei Dihuangwan with rational concentration into culture solution of rat osteoblast, later using MT method for determining the(More)
OBJECTIVE To study the effects of Naoan tablets on brain hemodynamics and cerebral microcirculation of soft membrane. METHOD Cerebral blood stream flux, resistance of blood vessels, blood pressure and heart rate were used as observation indexes in hemodynamics experiment. Artery caliber and the number of capillaries with recovered blood stream were used(More)
OBJECTIVE Comparative study of type 2 diabetes and healthy controls by metabolomics methods to explore the pathogenesis of Type II diabetes. METHODS Gas chromatography - mass spectrometry (GC-MS) with a variety of multivariate statistical analysis methods to the healthy control group 58 cases, 68 cases of Type II diabetes group were analyzed.(More)
An Er-doped fiber (EDF) filter was used in a double-pass backward Er-doped superfluorescent fiber source (SFS) to improve its mean wavelength thermal stability. The thermal stabilities of mean wavelength for four configurations of SFS with or without the Er-doped fiber filter and Faraday rotator mirror were explored experimentally. The result shows that(More)
