The author summarizes their experience in nursing 15 patients who underwent reconstruction of the temporomandibular joint with autogenous bone graft . peri - operative psychological care is of significance in helping the patients maintain a good mental state and smooth recovery ; pre - operative oral nursing and skin preparation are the prerequisite conditions for the survival of the graft and the prevention of wound infection ; post - operative observation and care of the local wound are the determinant factors for survival of the graft ; early and persistent functional training is positive for improving the function of the temporomandibular joint 总结了对15例实施自体骨移植颞颌关节重建术患者的护理体会，认为围手术期的心理护理对于使患者保持良好的心理状态，促进其病情的顺利恢复具有重要意义；术前的口腔护理和皮肤准备是预防伤口感染、保证移植骨成活和伤口愈合的前提；术后局部伤口的观察与护理是关系到移植骨能否成活的关键；早期和长期有效的功能锻炼对于颞颌关节功能的改善具有积极意义。
Using those techniques , it is possible to reconstruct vascular model in vitro whose structure and function are same as autogenous vessels . in this experiment two degradable materials were precoated with cross - linked type i collagen , moulded into tubular porous scaffold , and then seeded with ecs . using rotary cell culture technique , vascular model was constructed in vitro 本实验采用胶原与几种可降解材料相复合，构成管形支架，在体外环境下，探索构建分别含内皮细胞、平滑肌细胞及成纤维细胞的三层结构的组织工程化血管，三种细胞相互作用、相互支持，形成一个在形态和功能与正常血管近似的组织工程化血管。
In the paper , not only such factors as reinforcing steel bar , various placing temperature of concrete in case of lift placements , lift thickness , time interval between lifts , the variation of elastic modules of concrete , heat of hydration , the temperature changes of environment but the effect of creep deformation and autogenous volume change on the temperature field and thermal stress field of reinforced concrete face - slab are considered 本论文在分析中，考虑了钢筋、混凝土分层浇筑、入仓温度、浇筑层厚、施工间歇、混凝土弹性模量变化、水化热发散规律、外界气温等因素的变化及混凝土徐变和自生体积变形等因素对面板温度场和温度应力的影响。
3 . with the consider of one mgo concrete arch dam in guangdong province , its construct course was simulated and its thermal field , autogenous volume expansion field , strain field , stress field and displacement field were also analyzed . at the same time , the simulated analysis theory and accuracy and rationality of the program were validated in comparison with the prototype observation data 3 、结合广东某外掺mgo混凝土拱坝，对其施工过程进行了模拟，完成了坝体的温度场、自生体积膨胀场、应变场、应力场及位移场的实时仿真分析，同时结合原型观测资料的分析，对仿真分析成果进行了验证。
The result of the study demonstrate the pt autograft which have blood supply can promote the reversion of biomechanics properties , the action mechanism is maybe related with the ischemic necrosis and revascularization of the graft . transplanted autogenous patellar - tendon grafts undergo a process of ischemic necrosis , revascularization , proliferation , and remodeling 其作用机理可能与移植物缺，血坏死和再血管化有关，移植物在向前交叉韧带样变过程中，移植物的修复均经历缺血坏死，血管重建，细胞增殖，再塑型期。
In the program , the effect of lamination placement , construction interval , elastic modulus change , thermal insulation change , surrounding temperature change , concrete creep and autogenous volume change on thermal stress are considered . and such temperature control measurement as water pipe cooling , heat preservation of the dam surface , the pouring temperature control , the overflow across the dam top during flood season can also be simulated by numerical method 该程序在编制过程中考虑了混凝土分层浇筑、施工间歇、弹模变化、绝热温升过程、环境温度的变化、混凝土徐变、自生体积变形等因素对坝体温度场及温度应力场的影响，同时也考虑了水管冷却、坝体表面保温、控制浇筑温度、施工汛期坝顶面过水等各种温控措施的数值模拟。
In this article , according to heat conduction theory , elastic creep theory and finite element theory , the temperature field and creep stress field in the arch dam during construction and operation are simulated and analyzed by means of three dimensional finite element relocating mesh method , and the distribution law of the temperature field and creep stress field in the arch dam during construction and operation are systematically studied , and according to the construction process of concrete arch dam , the effect of lamination placement , construction interval , elastic modulus change , thermal insulation change , surrounding temperature change , concrete creep and autogenous volume change on thermal stress in the arch dam are also considered 论文根据热传导理论、弹性徐变理论及有限元理论，用三维有限元浮动网格法对拱坝施工期和运行期温度场、徐变应力场进行了全过程仿真分析，较为系统的研究了混凝土拱坝施工期和运行期温度场、徐变应力场的分布规律，在分析中按照混凝土拱坝施工过程，考虑了混凝土分层浇筑、施工间隙时间、弹模变化、绝热温升过程、环境温度的变化、混凝土徐变、自生体积变形等因素对坝体温度应力的影响。
The disadvantages of dual grafts are the same as those of single cortical grafts : ( 1 ) they are not as strong as metallic fixation devices ; ( 2 ) an extremity must usually serve as a donor site if autogenous grafts are used ; and ( 3 ) they are not as osteogenic as autogenous iliac grafts , and the surgery necessary to obtain them has more risk 双侧植骨的缺点与单侧皮质骨植骨的缺点相似：强度不如金属固定器械；采用自体骨移植时必须选择肢体作为供区；成骨性能不如自体髂骨移植，取骨手术也有更大的风险。
