Compared with the finite element analysis
In this paper, a computational model of the Pazhou main bridge is established by Midas / Civil professional software , the establishment of a total of 573 nodes, 574 beam elements, loaded by design load car-Super 20 fleet, the fleet loads traveling speed Pazhou Bridge with the design speed of 60km /h , the damping ratio of the bridge is 0.05s, The mode superposition method is used to the process transient analysis, the analysis time is 1150s, with a time step of 0.05 seconds.

The grade of masonry mortar is 0(because of the water erosion), so the strength of masonry mortar, f, is 1.07N/mm2.
The decoration and construction workers are short of professional knowledge and they have ambiguous concepts that the main load-bearing component could not been removed, so the results of "destruction before decoration" often appear.

Introduction
General procedures that professional dentists carry out to prevent dental caries are topical fluoride
application and pit and fissure sealing, although many amenable methods, like teeth brushing and
taking fluoride, diet control, are.
The artificial saliva was prepared immediately before being used and consisted of 0.4 g NaCl; 0.4 g KCl; 0.795 g CaCl2·2H2O; 0.780 g NaH2PO4·2H2O; 0.005 g Na2S·9 H2O; 1.0 g urea; and distilled water up to 1000 mL.

Due to the fact that these alloys are absorbed in the internal environment of living organisms, they present two major advantages regarding: the physical and psycho-emotional impact on the patient and the substantially reduced extra costs following medical intervention (surgery, recovery and professional reintegration).
Three MgSiCa alloys were obtained by induction melting using an original casting procedure in argon atmosphere. [5] As cast specimens were homogenized (573K/24h/water) and hot laminated (60% thickness reduction) at 673K-723K.
