3.Bats are the only mammals capable of sustained flight,and,unlike birds,they can fly at relatively low speed with extreme maneuverability.
蝙蝠是唯一能够持续行的哺乳动物,与鸟类不同的是,它们行速度较,但极具机动性.收藏指正
4.By testing the value of pH of fly ash cement hydrated 28 days later with the dosage of fly ash from 0~70%, it can be found that the value of pH of fly ash cement is bigger than 11.5 even hydrated 28 days, so it does not result in the alkalinity of fly ash cement too low consequently influencing the property of protecting reinforcing steel bar.
通过测试掺入粉煤灰的水泥水化28d的pH值,可以看出即使是粉煤灰掺量在70%时,其水化28d的pH值也大于11.5,不会导致粉煤灰水泥的碱度过,影响其护筋性.收藏指正
5.Preparation of PASS is a new approach of comprehensive utilization of fly ash with uncomplicated process, low cost and simultaneousness of silicon and aluminum in fly ash.

9.Abstract: Controlling AAR with high quality I grade fly ash has been researched.The result shows that the content is more important than the quality for the effect on controlling AAR.The solubility of the fly ash contained alkali is inquired in differ alkali concentration solution.The mechanism of low content accelerating swell and yet high content controlling swell is discussed when controlling AAR with the fly ash contained high alkali content.
文摘:研究优质Ⅰ级粉煤灰对碱骨料反应的抑制效果,结果表明,用粉煤灰抑制碱骨料反应,其掺量因素的影响大于品质因素的影响;探讨了粉煤灰中的碱在不同浓度碱溶液中的溶出情况及用高碱含量粉煤灰抑制碱骨料反应时,掺量促进膨胀,高掺量抑制膨胀的机理。收藏指正
