常見(jiàn)例句The cross ratio he called anharmonic ratio. 他把交比叫作非調(diào)和比。Desargues proved that the cross ratio is the same for every section of the projection. Desargues證明了投射線(xiàn)的每個(gè)截線(xiàn)上的交比都相等。Cross ratio, i.e. conditional hazard ratio, function had been used to measure the dependence between bivariate failure times. 交叉比可用于估計(jì)生存時(shí)間資料的家庭相關(guān)。In the calibration of the system,a plan based on the principle of cross ratio invariance in algebraic projective geometry was used to calibrate the coded light planes. 在對(duì)編碼投影光平面的標(biāo)定過(guò)程中,提出利用代數(shù)射影幾何中的交比不變?cè)韺?duì)其進(jìn)行標(biāo)定的方案,并論述了標(biāo)定原理。In the calibration of the system, a plan based on the principle of cross ratio invariance in algebraic projective geometry was used to calibrate the coded light planes. 在對(duì)編碼投影光平面的標(biāo)定過(guò)程中,提出利用代數(shù)射影幾何中的交比不變?cè)韺?duì)其進(jìn)行標(biāo)定的方案,并論述了標(biāo)定原理。Any transformation which preserves the cross ratios according to isomorphism would have the semi-linear transformrions as its representative. 又指出,如果保加的位置變換的值域不止一維,則它也是半線(xiàn)性變換; 返回 cross-ratio
