It was found that there was a close relationship between the adhesion strength of the bg coating and the surface roughness of the titanium alloy and the firing temperature . the chemical state of the elements ti and si at the coating interface varied . the chemical bond and the mechanical occluding make the bg coating form a strong adhesion with the titanium alloy 通过研究发现， bg涂层与基体的结合强度与基体表面的粗糙度以及烧成温度密切相关，涂层界面处ti元素和si元素的化学状态发生了变化， bg与基体强结合的机制为化学键和机械嵌合两种力共同作用。
In order to express the recombinant peptide of both gp52 and pp150 oterminal peptides from human cytomegalovirus ( hcmv ) , which seem to show good antigenicity . recombinant dna technology was used to construct recombinant plasmid , which was transformed into the pichia pastoris to express the interesting peptide 为了表达人巨细胞病毒( humancytomegalovirus ， hcmv )中抗原性较强的两段蛋白片段? gp52c末端和pp150c末端的嵌合肽，用基因工程技术构建适于酵母表达系统的重组表达质粒。
The paper validates and perfects the traditional wear theory by using the ferrography , at the same time , combining the practice , mechanical embedded minor particles , scoring , plastic distortion , shaping effect and fatigue effect are analyzed and the results show that the vehicle ' s malfunction can be predicted 文章作者将铁谱磨粒分析技术运用在汽车维修行业，验证和完善了传统磨损理论，并结合实践，对微凸体机械嵌合、胶合，塑料变形及刨削作用和疲劳作用进行了分析，证明汽车机械故障可以预测，且可以防止重大事故的发生。
