查询词典 experimental

To conduct such research a new experimental apparatus was established.With this setup the two-photon excitation spectra of Barium and one-photonexcitation spectra of Strontium Rydberg atoms were recorded and identified.The Stark spectra of Strontium atoms showed the "l-mixing" and "n-mixing"features. By changing laser wavelength and external electric field strengthsimultaneously, the scaled-energy spectra of Strontium 〓 Rydberg atomsat constant scaled-energy ε=-3.00,-2.50 and -1.88 were recorded for thefirst time. The experimental spectra were Fourier transformed and yielded therecurrence spectra.

METHODS: In the experimental group, ADSCs were cultured with the scaffold and induced by CDMP1(50 μg/L) in basic medium for another 2 weeks. In the control group, SD rat cartilage cells were cultured with elementary nutrient liquid with scaffold for another 2 weeks. Twenty nude mice were imbedded the composite of cells-scaffold of the experimental group in their left armpits and the composites of cells-scaffold of the control group in right armpits. Every ten nude mice were killed at 8 and 12 weeks and were examined by safranine O-fast green and toluidine blue staining.

The behavior of post-tensioned steel beam-to-CFT column connections with energy dissipating bars has been investigated analytically and experimentally. Experimental results demonstrated that the connections possess self-centering response, gap opening and closing at the beam-to-column interface, energy dissipation characteristics, and no inelastic or residual deformation. Moreover analytical predictions correlated well with the experimental results.
