compound proportion
1.1.120 clean class wistar rats were fed of the compound in the proportion of distilledspirit4.8g/(kg·d),pyrazole24mg/(kg·d)、maize oil2ml/(kg·d),with high fat feedstuff(common feedstuff: cholesterol: lard=79%:1%:20%)to make the animal models of ALF.
2.change (a compound) by increasing the proportion of the electronegative part; or change (an element or ion) from a lower to a higher positive valence: remove one or more electrons from (an atom, ion, or molecule).
3.With nano-ZnO as carrier,the Ce4+/ZnO compound powder has been prepared. The influences of different proportion of ZnO and Ce4+ on doping ratio were investigated.
4.And then composite proportion tests are carried out on retarded components and optimalhigh efficient water reducing agent and the formulae of super retarding compound additive is determined.
5.The results showed that 20～25 phr of emulsion PVC could replace the equivelent proportion of NBR in CR/NBR/CPE(40/40/20) blend and 40～60 phr of suspension PVC cound replace the equivelent proportion of NBR in NBR based compound for belt cover;
6.Moreover atomic absorption spectroscopy (AAS) method was used to determine the proportion of impurity elements in the pioneer-precipitate of the compound powders. The hardness Hy and fracture toughness KIC of the targets were determined through microhardness analysis.
7.After compound of spontaneous combustion gangue powder and fly ash, that water demand of gelled material systems is decreased than that of only mixing spontaneous combustion gangue powder and the tendency of water demand is gradually increasing with the increment of the proportion of spontaneous combustion gangue powder in powdery materials.
8.Abstract: By adding into concrete batch with greater proportion of active fine additive and pumping agent,reacted to the compound impact of the two substances,concrete workability,durability and strength could be improved.In addition,pumping-suitability of low strength concrete may be improved as well.
