The reason for this is probably that autogenous veins lack sufficient external support , thereby impeding some regenerating units from reaching distal target organs 原因是静脉本身较没有弹性，容易受到周围组织的压挤而影响神经的再生。
At the primeval moulded time , cracks are mainly caused by temperature shrinkage and autogenous shrinkage , after that , it is mostly caused by dry shrinkage 混凝土浇筑初期开裂主要是温度变形和自收缩引起，后期开裂则主要是因干缩所致。
Moreover , the autogenous shrinkage and the possibility of cracking in the early stage of the hpc also can be controlled , with the addition of the mineral additives 掺和料的加入还可以减小混凝土早期的自收缩，减少高性能混凝土早期开裂的几率。
Autogenous palatal mucosal graft ( pmg ) has been considered the most predictable grafting material when utilized to increase attached keratinized gingiva 摘要在增加角化附连牙龈的手术中，自体腭黏膜移植体一向被认为是可预测性最佳的一种植体材料。
The fixation method of transcalvarial suture takes advantages of the depth and configuration of the calvarium , allowing the use of autogenous material 从发际到中脸部整个皮肤瓣，经头骨上方将下垂的肌膜做上滑式的束紧悬吊，来达到上额拉皮的美容效果。
Autogenous periosteum offers advantages over other tissues as graft material , since , it is easy to handle , strong and vascular , and produces no immune reaction 以自体骨膜做移值片有以下的优点；即它是柔软的、容易操纵及处理、强?且含有血管，以及不产生任何免疫反应。
In both models two - step regressive equations are adopted to simulate the step of quick development and the step of even change of hydration reaction and autogenous shrinkage 这2个模型均采用两阶段的经验公式，分别用于模拟水化反应和自收缩的快速发展阶段与平稳变化阶段。
The dynamic models of hydration reaction of cement and autogenous shrinkage of concrete were constructed respectively based on the multi - composition and multi - scale hydration reaction of cement 摘要基于水泥的多组分和多尺度水化反应的原理，分别建立了水泥的水化反应和混凝土自收缩的动力学模型。
