In this paper, the effect of molding pressure on the strength and hydrochloric acid stability of autoclaved lime_stone sand brick is studied. 研究成型压力对蒸压灰砂砖抗压强度和耐盐酸腐蚀能力的影响 .
Because of its acid stability between pH3~pH10, CVB3 could survive transit through the stomach and become implanted in the lower intestinal tract. 作为肠道感染病毒，CVB3在pH 3~10范围内稳定，并通过与细胞膜上的CAR/CD55/DAF结合宿主细胞，导致隐藏于核衣壳内部的VP4和VP1蛋白暴露于病毒表面，促进细胞膜对CVB3的包裹和摄入。
The acid stability,of rif- ampicin micro pill capsules is better than that of the rifampicin gastric capsules,the rifampicin micro pill capsules suppress the decompose of rifampicin and decrease the sub responses of rifampicin. 利福平微丸胶囊较利福平胃溶胶囊的酸稳定性好,抑制了利福平的降解,从而减少了毒副反应。
The results show, when molding pressure changes from 20 MPa to 40 MPa, autoclaved lime_sand bricks get a strength increase of 90.3 percent. Hydrochloric acid stability is also enhanced. 研究表明
