A rapid and simple method for the determination of colistin A and B in fishery products by reversed phase ultra performance liquid chromatography with positive electrospray ionization tandem spectrometry (UPLC-ESI-MS/MS) method was described. The samples were extracted with 1.0 mol/L of hydrochloric acid in methanol-water and then purified on the PLS solid(More)
In order to improve the robustness of the active suspension while ensuring its performance, variable structure model following control (VSMFC) theory was applied to the design of the controller for active suspensions of 4-degree-of-freedom (4-DOF) automobile model in this paper. The sliding mode equation was derived by using VSMFC theory and the parameters(More)
The dynamic system with time-delay exists in various engineering fields. A delayed controlled machine system can be dispersed into an ordinary differential equation with time-delay. The precise integral algorithm used in the paper is a new method for finding the solution of time-delay dynamics systems. Disperse the system equation by treating the delay term(More)
Hydraulic accumulator type braking energy regeneration system have the advantages of high power density, low cost and reliable property, which is suitable for the traditional engine driving bus. The variable displacement hydraulic pump/motor is used the braking energy recovery system as regeneration conversion device, its structure parameters affected(More)
A verified method for measuring Semicarbazide (SEM) in seawater, sediments, and shellfish was developed based on ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). A total of 30 stations were radially distributed in Jincheng and Sishili Bays in the Bohai and Yellow Seas, and 1025 monitoring data were collected in 41 voyages, 615(More)
