It has been proposed that the use of a ferrule as part of the core or artificial crown may be of benefit in reinforcing the endodontically treated teeth restored with post - and - core systems 桩核修复时,在残冠残根的断面设计箍结构,使其成为桩核或冠修复体的一部分,由此产生的箍效应可以增强修复后牙体组织的机械强度,从而受到越来越多的重视。
Combining with the results of implant test , the conclusion that the main reason of dropping the strength of austenite zone is the micro - crack located in the tip of flake graphite and marten site is drawn 结合插销试验结果提出了马氏体相变过程中，在片状石墨尖端及马氏体组织中造成的微裂纹是奥氏体区强度下降并进而在外力作用下断裂的主要原因。
The results show that , when the hardfacing process is not appropriate , the thick martensite structure with high carbon content will form in the overheat region of heat affected zone , and the high residual stress occurred , which are the primary causes resulting in crack 结果表明，堆焊工艺制定不当，热影响区的过热区形成高碳粗大马氏体组织及保留了较大的焊接应力，是导致堆焊层开裂的主要原因。
What is becoming evident is that both fat and lean are essential tissues for reproduction and the objective of the feeding program for replacement gilts should be to manipulate the body composition of the gilt to ensure that adequate reserves of these tissues are present at first mating 显而易见，脂肪和瘦肉都是保持良好繁殖性能必须的体组织，同时也是后备母猪饲喂目标：控制青年母猪的体组成，确保初配时有脂肪和瘦肉沉积。
The lath martensite nanometer structure can play the role of fine - particle strengthening and dislocation strengthening as well as coordinate the distribution of dislocation . it is hopeful that the strength and toughness of material with this structure can be increased at the same time 板条马氏体组织纳米化结构，可起到纳米晶粒的细晶强化与位错强化的联合作用，并可协调位错分布，有望使具有这种组织的材料强度和韧性同时得以提高。
Abstract : under the industrial scale test conditions the low carbon bainite steel having characteristics of bainite texture , high strength and toughness is produced by means of adjustment and control of the hot rolling process and the appropriate rolling schedule of the steel accordingly determined 文摘:在工业性试制的条件下，通过对热轧工艺的控制和调整，获得具有贝氏体组织特征的低碳贝氏体钢，该钢种具有高强度、高韧性的性能，并确定了其热轧工艺制度。
This paper describes the rule of group communication as the relationship between agents and the way individual adjusting their own opinion as agent decision - making function , and with the help of multi - agent organization simulation model , analyses influence of group characteristics and group communication policies on eventual group opinion patterns 摘要通过将群体沟通的规则和意见调整的方式，抽象成为多智能体组织中的智能体相互作用关系和个体决策函数，通过构建多智能体模型，模拟分析了群体不同的沟通特性和沟通策略对群体沟通最终意见模式的影响。
This article make certain the concept of content of city community management mode first , then quote the concept of community by ferdinand tonnies ( 1855 1936 ) , gemeinschaft : a german word , translated as ‘ community ’ , used by sociologist ferdinand tonnies ( 1855 - 1936 ) to define an ‘ ideal type ’ , or model , society where social bonds are personal and direct and there are strong shared values and beliefs . characteristic of small scale , localized societies , it is in contrast to gesellschaft which refers to complex , impersonal societies 本文首先对城市社区管理模式的一些内容进行概念界定,从德国社会学家滕尼斯对社区的定义出发,他指出社区是由自然意志形成的,以熟悉、同情、信任、相互依赖和社会粘着为特征的社会共同体组织;而社会则是由理性意志形成的,以陌生、反感、不信任、独立和社会连接为特征的社会结合体组织。
By means of mathematical analysis and computer simulation , the authors found out the characteristics of the multi - agent organization ' s behavior sod the perfect strategy for the individual agents to maximize their utility based on the specific assumptions about the size of , the product function of , and self - organization of the multi - agent organization 通过对多智能体组织模型的构建，借助数学分析和计算机模拟，得到了关于多智能体组织规模、生产函数和自组织工作等不同假设情况下的组织行为特点和个体最优行为策略。
After dna analysis , six white pigs is not present chimerism in various tissues . to one skin pigment piglet , chimerism is present in skin , brain , pancreas , pituitary gland and blood , but not in heart , lung , liver , spleen , kidney , intestine and ovary . the detection of another skin - pigment chimera is similar to the analysis result of wzsp 通过dna分析进一步得出，所产8头仔猪，其中六头白猪体组织未发现嵌合现象；其中一头皮肤色素嵌合体猪的皮肤、大脑、胰、甲状腺、血是嵌合的，而心、肺、肝、脾、肾、空肠、卵巢这些组织并没有嵌合；另一头皮肤色素嵌合体猪的检测结果和五指山猪取得相似的结果。
