The particles distributed hi the matrix of grey cast iron, but some contact each other. the composite layer extend gradually into the substrate. when volume fraction of wc is 36 wt % and 27 wt %, the matrix of the composite is high chromium cast iron, consist of white carbide bars and the austenite. wc particles distributed uniformly, retaining approximately quondam granular form in the composite layer which has an evident interface area with the substrate, with good bonding strength
對不同碳化鎢體積分數的灰鐵和低鉻鑄鐵基復合材料的微觀組織結構分析表明：碳化鎢體積分數為52時，復合層內基體為灰口鑄鐵組織，顆粒直接分佈在灰鐵基體上，部分碳化鎢顆粒有相互接觸的現象，基材與復合層之間沒有明顯的過渡；碳化鎢體積分數為36 、 27時，復合層內基體為高鉻鑄鐵，由面塊狀的奧氏體和白條狀碳化物組成，碳化鎢顆粒表面固溶於基體組織中，粒形基本保持完整，分佈均勻，與基體構成冶金結合，基材與復合層之間存在一個明顯的平緩過渡區。 -
In the second part, having considered reinforcement - soil and faceplate - soil contact elements, nonlinear finite element model of reinforced retaining walls including soil elements, contact elements, faceplate elements and reinforcement elements was established. numerical simulation of a reinforced retaining wall through dynamic finite element method was completed by ansys, and some qualitative conclusions about its dynamic behaviors were gained
第二部分使用大型通用有限元軟體ansys ，通過引入筋-土、面板-土接觸單元，建立了由土體單元、接觸單元、面板單元和加筋材單元組合的加筋土擋墻非線性有限元模式，進行了動力有限元數值模擬分析，得出了一些關于加筋土擋墻動力響應的定性結論。 -
Moreover, a special contact problems implying herein the contact between deformable body and rigid body such as rigid foundation and base, rigid retaining wall and backfill is studied
此外，還對變形體?剛體接觸進行了比較詳細的討論，剛性基礎?地基、剛性擋墻?墻後土體之間的作用均屬此類特殊的接觸問題。
