In ecap route c , in order to accommodate the severe shear deformation the deformation form of lamellae cementite in pearlitic steel include periodical bending , periodical shearing and shearing fracture etc 在c方式ecap变形中，珠光体钢65mn中的渗碳体以周期性的弯曲变形，周期性的剪切变形，剪切断裂等形式协调ecap的强烈塑性变形。
In addition , at the ultrastructure scale , there are evident differences in chloroplast . in lower salinity ( 50 , 100mm ) , the lamellae of stoma and grana in some chloroplast expanded lightly ; the boundary of the chloroplast was dim 在50 、 100mhnacl处理下，细胞中有些叶绿体的基质、基粒片层稍有变形，被膜界限出现模糊现象，类囊体出现膨大。
In a word , we can conclude from the test results and the theoretical analysis that using polymer cement mortar as lamella repairing layer of the cement concrete pavement has both economic benefits and social benefits 试验结果和理论分析表明，利用聚合物水泥砂浆对水泥混凝土路面进行薄层修补，具有很强的操作性和推广性，既有一定的经济效益，又有一定的社会效益。
The microstructure of lamellae pearlite has evolved ultrafine cementite particles throughout the ferrite matrix uniformly after five passes . the ferrite matrix is homogeneous grains , average grain size is - 0 . 3 m . 2 变形五道次后，片层状的珠光体组织演变成了超细的渗碳体颗粒均匀分布于铁素体基体的组织，铁素体基体为均匀的等轴晶，平均晶粒大小为0 . 3 m 。
In order to carry out the fem computation , 3 - d isoparametric joint element of finite thickness is used to simulate the structural jionts such as longtitudinal slots , and lamella finite element is utilized to simulate seams in dam body and fractures in foudation 利用有限厚度三维接缝单元模拟纵缝等结构缝，用薄层单元模拟再生缝及坝基断裂；并对有限元计算所得单元结点应力进行优化。
The main results are as the following : ( 1 ) the microstructure of lamellae pearlite has evolved ultrafine cementite particles throughout the ferrite matrix uniformly after four passes . the ferrite matrix is homogeneous grains , and average grain size is - 0 . 3um 主要结果如下： ( 1 ) ecap变形四道次后，片层状的珠光体组织演变为了超细的渗碳体颗粒均匀分布于亚微晶铁素体基体的组织。
The fracture and spheroidization of cementite shows obvious anisotropy . there are two possible mechanism about spheroidization of cementite : the fracture cementite lamellae grows up non - uniformly and the fine spherical cementite particles grows up as the core 渗碳体的破碎和球化表现出明显的各向异性。渗碳体的球化可能以两种机制进行：破碎渗碳体片的非均匀长大和细小球状渗碳体颗粒的形核长大。
During the process of senescence , the structural abnormality occurred firstly in chloroplast in which chloroplast grana disordered and stromal lamellae twisted and in which starch grains became bigger and osmiophilic granules increased , and then converged into bigger granules 叶绿体最早出现结构异常：基粒结构紊乱，基质内囊体发生扭曲、淀粉粒由小变大、嗜锇颗粒由少变多再逐渐汇集成大的颗粒。
24 samples including matsutake basidiocarps and different origin isolates were analyzed with rapd fingerprinting comparison using 17 arbitrary decamer nucleotide primers . the results showed that all slow - growing mycelia isolated from lamellae have the same dna fingerprinting 试验还对松茸菌根、带菌丝土壤进行了分离，结果很容易获得各种快生型的丝状真菌，因此认为菌根、土壤并不适合分离松口蘑菌丝体。
This paper mainly has narrated the foundation knowledge of the fem ( finite element mesh ) superposition method in detail and also given examples for the question of the stress concentration of the metal lamella to the calculation precision of the finite element mesh superposition method and its using 摘要主要针对有限元网格重合法进行介绍，并以金属薄板的应力集中问题为例，探讨了有限元网格重合法的计算精度和实际应用。
