The research results show that, from the viewpoint of second phase morphologies, there exist quite differences between the grain - type materials ( such as wc / bcu brazing deposit material, wrs1000 and 1zt tungsten carbide strengthening overlaying material, as well as the wear - resistant material of polymer adhesive coating etc. ), and the aggregation - type as well as dispersion - type ones ( such as zg35simn, wrd - 1 and khc - k2 depositing material ) in the wear - resistance and sand slurry abrasion mechanism. the sand slurry abrasion mechanisms are brought forward, of new wear - resistant materials with the features of grain - type second phase morphologies

This article introduces briefly the process of design and characteristic of structure of db930 tube and discusses the main problems of technology and technique which was met during the manufacture and the measures having been adopted are emphatically. it discusses the solve measures in following six aspects : the filament current is too large, carbon deposits during the carbonizing of cathode, the capacitance between the first grid and the second grid is too large, transpiring happens inside the tube, the insulation resistance between the electrodes is too lower when the filament is on and the ability of bearing high voltage is too lower

In this paper, the effects of fly ash, cement, lime, fine sands, foam agent, w / c ratio and additional agent on foamed concrete were studied by experiments, the best combination ratio of fly ash foamed concrete whose density varies from 551kg / m3 to 650kg / m3 was obtained through orthogonal test design, the foam agent quantity and the fly ash quantity effect the fly ash foamed concrete greatly, so the author selected them as independents to establish duality linear regression equations, the equations were quite ideal through the test of model summary r. moreover, the author also did some experiments about the water resistance of magnesium oxychloride cement fly ash foamed concrete, the outcome showed that phosphoric acid has good effect on water resistance, and its appropriate quantity was found
