Researches of schistosomiasis vaccines have gone more than 60 years, approximately including from the stages of dead vaccine and live vaccine ( irradiated attenuated cercariae vaccine ) to gene engineered vaccine, etc. many different forms of vaccines have been tested in animal models, including gluthathione s - transferase, paramyosin, irv - 5, triose phosphate isomerase, sm23, fatty acid binding protein ; which were considered promising by who / tdr. but none of them steadily accomplished the pre - set target level of 40 % protection. in order to enhance the protective capacity further, it is essential to develop novel vaccine antigens and / or vaccine adjuvants
血吸蟲病疫苗研究已有60多年的歷史,大致經歷了死疫苗、活疫苗(照射致弱
尾蚴疫苗)和基因工程疫苗等研究階段,產生了一些who / tdr推薦認為很有希望的疫苗候選分子,如谷胱甘肽- s -轉移酶( gst ) 、副肌球蛋白( sm97 ) 、照射致弱疫苗抗原5 ( irv - 5 ) 、磷酸丙糖異構酶( tpi ) 、曼氏血吸蟲膜內在蛋白( sm23 )和脂肪酸結合蛋白( fabp , sm14 )等,但其對宿主的保護作用均不甚理想,未能穩定地達到40或以上的保護力水
平,因此有必要繼續尋找新的疫苗抗原分子和/或疫苗佐劑,進一步提高其保護力。

First, the theory of fretting wear and studies on fretting fatigue were introduced and the parametric method was used in the process of creating the model of dovetail joints in ug software. the elastic contact problem is analyzed in finite element method ( fem ) and is used to the parameters " distribution and contact stress of the joint are obtained on the base of ansys code. with the effect factor of load frequency, the prediction method of fretting fatigue life of dovetail joint under low and high / low cycle complex load is proposed
本文介紹了微動損傷的機理和微動疲勞壽命的研究方法;利用ug軟體對燕
尾榫聯接結構創建了參數化實體模型;基於ansys軟體
平臺求解彈性接觸問題,獲得了榫聯接結構接觸應力及接觸狀態量的分佈;在已有微動疲勞壽命預測模型的基礎上,引入載荷頻率影響因子,對低周、高低周復合載荷作用下的燕
尾榫聯接結構進行了微動疲勞壽命的預測,與試驗結果對比表明採用本文提出的方法預測榫聯接結構的微動疲勞壽命是有效的。
