Rubber , vulcanized - test method of aging by heat and air pressure 硫化橡膠壓力空氣熱老化試驗(yàn)方法
Progress in the study of epidemiology and test method of age - related macular degeneration 老年黃斑變性的流行病學(xué)和檢查方法研究進(jìn)展
Using the time dependent finite element method of age - adjusted effective modulus , the author calculates the deflection which is induced by shrinkage and creep in a continuous rigid frame bridge of urban rail transit , and further compares with the site test result , the conclusion is very meaningful 摘要采用按齡期調(diào)整有效模量的時(shí)變分析有限元法,對(duì)城市軌道交通預(yù)應(yīng)力混凝土連續(xù)剛構(gòu)橋的收縮徐變變形進(jìn)行了理論計(jì)算,并與實(shí)測(cè)結(jié)果進(jìn)行了對(duì)比分析,結(jié)果表明理論計(jì)算是可信的。
