With the rapid development of new economy, China lubricant enterprises urgently need to implement effective Customer Relationship Management (CRM) to win the market. By constructing and applying CRM, lubricant enterprises can keep their old customers and find potential customers, so the profit and core competitive power of lubricant enterprises can all be increased. In this paper we optimized the...
The function of a constructed wetland system may be affected by high ammonia concentrations, which are toxic to wetland plants. This research was conducted to assess the tolerance of Phragmites australis to ammonia. P. australis is a reed species commonly used in constructed wetlands. The photosynthetic rate (Pn), peroxidase (POD), catalase (CAT), and superoxide dismutase (SOD) activities and the...
Laser Induced Fluoresces (LIF) and laser cavity ring-down spectroscopy (CRDS) have been recently developed in our group for diagnosis of the active species (atoms, ions or radicals) in reactive plasmas. In the first experimental approach, time-resolved LIF technique was used to investigate the temporal evolutions of the number density of metastable state N2 (A) in the nanosecond pulsed post discharge...
In this paper, Through quasi-static test on four concrete-filled rectangular steel tubular (CFRST) beam and column joint model, the mechanical and seismic behavior such as hysteretic curve, ductility, degradation of strength and stiffness, energy dissipation capacity and failure characteristics etc, are researched. The results indicate that the CFRST beam and column joints subjected to low cycle reversal...
