The maximal tension stresses in surface and base between induced crack have been obtained by parametric analysis 通過結(jié)構(gòu)參數(shù)分析掌握了預(yù)切縫間面層、基層中最大拉應(yīng)力的分布規(guī)律。
Then , taking the maximal tension stress in surface and base and the stress intensity factor at the top of the induced crack as restraining indexes , method to determine the reasonable induced spacing has been determined 然后以預(yù)切縫上端應(yīng)力強(qiáng)度因子、面層與基層內(nèi)的最大拉應(yīng)力為約束指標(biāo)建立了合理預(yù)切縫間距的確定方法。
After a maximal response to kc1 was obtained under an initial tension of 2 g , isometric contractions induced by iron or pe were measured , and calculated as percentage of the maximal tension induced by kc1 . the rings with or without endothelium were preconstricted with 10 " 6mol / l of pe and a cumulative concentration - response curve to ach , or sodium nitroprusside ( snp ) , or l - arginine ( l - arg ) was obtained 用10 ~ ( - 6 ) mol lpe預(yù)收縮后,加入不同濃度的ach 、硝普鈉( snp )或l -精氨酸( l - arg ) ,浙江大學(xué)碩士學(xué)位論文以各種濃度所致的舒張幅度達(dá)到pe所致的收縮幅度的百分比作血管舒張反應(yīng)的量效曲線。
