2.PLC Application in Liquid Steel Test Gas Sample Transfer System in AISC No.3 Steelmaking Plant
3.The glass powder size, morphology and mechanical properties of glass/epoxy composites were measured by means of laser particle size analyzer, SEM, material testing machine and TGA respectively.
4.The paper mainly explores the effect of specimen size and aggregate diameter on concrete strength and guantitatively reveals the effect of the factors,such as specimen size, aggregate diameter, age and cement water ratio,etc, on strength by applying multivariate regression analysis.
5.2) The influencing factors of Kaiser effect such as loading pattern, loading rate, grade of strength, size of specimen, aggregate size, stress level, time delay and wet-dry condition are discussed and analyzed.
6.In this study, flexural strength of vita In - ceram alumina specimens infiltrated with G1-Ⅱ La and G1-Ⅱ Ce glass were determined by means of three point bending test,and were compared with those of the specimens infiltratedwith G1-Ⅱ and vita In - ceram glass.
7.The results show that the magnesia-hercynite specimen fired at 1600 ℃ was densified,and the specimen with 7% hercynite has the highest cold crushing strength and adhesive strength(showing its coatability).
8.The thermal oxidation stability of four kinds of PPR resins for hot water pipe applications, which are PPR-4, TPC-5, PPR-2 and PPR-16, has been studied by use of fundamental experiment method(T=125 C ,d=0.5mm) based on the accelerated testing method developed by our laboratory.
9.Except in 31～32 weeks age , there was significant difference among groups in 27～34 weeks age (P < 0. 05) , and the laying rate of Black - bone chicken with lower deitary protein level in 41～48 weeks age was higher than those with higher protein level, but the difference was not significant( P > 0. 05) .
10.The Marshall samples of asphalt mixture with polyester fibers dosage of 0, 0.15%, 0.2%, 0.25%, 0.3%, were tested on MTS810 under temperature of 15℃.
