查询词典 a mass of

In the ESI+ mode the compound isolated from fraction III/9 showed a pseudo-molecular ion of m/z 261 ([M + 1]+) as well as sodium and potassium adducts with m/z 283 and m/z 299, respectively, thus suggesting a molecular mass of 260 Da.

In this research, swainsonine contents of three Oxytropis species were determined by the high performance liquid chromatography coupled to mass spectrometry. The population genetic diversity was also studied and the swainsonine related molecular markers were screened by ISSR. In vitro fungi cultures from the individual plant of O. glabra were performed and microbiological morphology of the colony and the conidiophore were investigated. The 5.8S rDNA/ITS sequences of fungi amplified from total DNA in both plants and fungal endophytes were studied. These sequences were analysed and compared, and they were also compared to the 5.8S rDNA/ITS sequence of fungal enduphyte Embellisia sp. L12 from the O.lambertii, O.sericea and A.mollisimus distributed in USA.

The result was a firman of 1690, by which the Franciscans were to be reintegrated as they had been prior to 1630. The sentence was solemnly published in Jerusalem on June 25, 1690 in the presence of the authorities and the contending parties. On June 29th the Franciscan Custos, with a solemn Mass, took again possession of the Holy Sepulchre and other sites within the Basilica.

The governing equation of in-plane vibration of cable-restraint system is derived by means of D'Alembert principle, and then those partial differential equations are transformed into a set of ordinary differential equations by Garlerkin method. The method of Runge-Kutta integration is applied to solve the equation. The simulation analysis is made to prove that this vibration control has obvious damping effects and then the influence of cable tension, support mass, natural frequency and spring stiffness on the damping are discussed. Eventually, the approximate analytic solution of the optimum damping parameter is obtained to provide a simple and effective reference and design method for the engineers.
