英文
embedded in masonry-
The interface mechanical finite element matrix matching method and the thermal stress for the masonry envelop in the wall of melting furnace
熔煉爐壁中砌體的界面力學有限元矩陣對號入座法與熱應力The forming - nucleus drive power could form numerous little crystal nucleus under natural melting temperature. the formation of tic particles in the melt could be divided into two phases which was forming - nucleus and growth. the forming mechanism of tic was : melting ti first surrounded c, then ti melting in the alloy and c formed a complicated reaction mesosphere on the carbon surface
根據熱力學及動力學分析，認為在碳顆粒界面處tic的形核率很高，形核驅動力足以在正常的熔煉溫度下形成眾多的小晶核；熔體中tic顆粒的合成可分為形核與長大兩個階段，其形核機制為：首先活性ti原子包圍c ，溶入合金中的ti與c在碳表面形成一復雜反應中間層，隨著反應進行， ti和c顆粒不斷減少，生成的tic不斷彌散分佈於熔體中；其長大過程伴隨著tic顆粒的相互堆砌、聚集和形態規則化。The productions include : 1. the investigation of crackss of masonry structures, the characteristic and the reason on cracks of wall ; 2. the limited element analysis about datum of brick - wall the relation between the maximal stress in wall and the relative sedimentation of foundations, the relation between the cracks form in wall and inner stress, the validity of limited element mode ; 3. the limited element analysis about the relative sedimentation of foundations, the influence of ratio of length and height, foundations rigidity, groundsill rigidity on the inner stress in wall ; 4. the limited element analysis about the influence of temperature on wall cracks and the influence of space between extension cracks, difference in temperature on the inner stress in wall ; 5. the analysis about the cracks rule because of temperature, the contrast between the result and the simulant result ; 6. the study about the influence of cracks of masonry structures because of constriction stress, the experience of dealing with constriction cracks in the domestic and the foreign ; 7. the advice of avoiding cracks because of the asymmetric sedimentation temperature, constringency in design and construction
