  1. The integrated system of smelting reduction ironmaking - gasolinesynthesis - electric - ity generation, in which the coal gas produced inthe ironmaking module is first cleaned and then used as the fuel for theelectricity generation module or raw material of the gasoline synthesismodule, can resolve the problem of utilization of tail gas in thesmelting reduction ironmaking and the large investment of gasificationin the integrated gasification combined cycle and gasoline synthesis. taking efficiency, scale and product structure into consideration, the processes of the two - stage smelting reduction ironmaking - combined cycleelectricity generation with coal gas, the two - stage smeltingreduction ironmaking - steam cycle electricity generation with coal gas, the one - stage smelting reduction ironmaking - combined cycleelectricity generation with coal gas, and the one - stagesmelting reduction ironmaking - gasoline synthesis with coal gas - steamcycle electricity generation with tail gas are techno - economicallyfeasible and have the promise of being industrialized

    將熔態還原煉鐵產生的煤氣在凈化后發電或經改質后合成汽油的集成系統可以解決熔態還原煉鐵的尾氣利用問題及聯合循環發電和煤基汽油合成造氣投資成本高的問題.從效率、規模和產品結構各方面考慮,過程模擬結果顯示:二段法熔態還原煉鐵-煤氣聯合循環發電、二段法熔態還原煉鐵-煤氣蒸汽發電、一段法熔態還原煉鐵-煤氣聯合循環發電、一段法熔態還原煉鐵-煤氣合成汽油-尾氣蒸汽發電流程,有實現產業化的可能
  2. Early age cracking of concrete has re - emerged as an important issue all over the world in recent years. the stress, due to restrained volume change related to thermal deformation and shrinkage in the early age concrete, is the main driving force for the deleterious cracking in the construction stage. during the development of the stress, creep, a very important property of concrete, is always developing. creep contributes to 40 ? - 50 ? reduction of the elastically induced stress in the restrained specimen. ring test, a qualitative test, can provide information to assess the potential for cracking of different concrete. an overview of ring test developed in recent years and mechanism of uniaxial tensile creep test is described in this paper at first. then, an innovative test equipment based on ring test is outlined

    近年來混凝土早期裂縫問題再次引起全球工程界的廣泛關注.早期混凝土由於體積變形受到約束而產生的應力是導致混凝土開裂的主要因素.在混凝土應力發展的同時,混凝土徐變也在同時發生著變化.有研究表明,徐變能減少40 ? - 50 ?的早期應力.圓環試驗是用於定性評價混凝土材料抗裂性能的試驗方法之一.本文首先分析了圓環試驗和單軸拉伸徐變試驗的原理,創造性地將圓環試驗用於測量早期混凝土的干縮徐變,並設計了試驗方案
