伸长比 meaning in Chinese

coefficient of extension
elongation ratio
extension ratio
ratio of elongation

When putting the static curve with the elongation of 1 . 4 and the dynamic curves in different pressure together , we can find that the slope coefficients of the static curve increase with the growth of radius
把伸长比为1 . 4时的静态曲线和三种压力水平下的动态曲线放在一起，从静态曲线可以看出，当直径增大时，曲线的斜率也逐渐增大。
From the statistics on the slope coefficients of the dynamic curves with the elongation ratio of 1 . 4 in the pressure of 60 - 100mmhg , 80 - 120mmhg , 100 - 140mmhg , we can conclude that there is no significant difference between the slope coefficients of the dynamic curves in different pressure
而在伸长比为1 . 4 ，压力水平分别为60 - 100mmhg ， 80 - 120mmhg ， 100 - 140mmhg时，动态曲线的斜率进行统计的结果表明，不同压力水平下的动态曲线斜率不具有明显差异。
