初始切线模量 meaning in English

initial tangent modulus
initial tangential modulus

Further more , on the basis of analysis of triaxial tests , the initial elastic modulus , poisson ' s ratio and strength index included in differ models is analyzed , and the damage characteristics of q3 loess is indicated on the basis of changing of the initial elastic modulus
进而，整理分析了不同模型共同含有的初始切线模量、泊松比及强度指标，并根据初始切线模量变化规律揭示了黄土结构损伤特性。
If asphalt concrete specimen is in stabilization by exert confining stress before the static triaxial test , it is then found that under the condition that time is long enough , the volume of the specimen will shorten gradually and stable around a fixed value , and the amount of compression is essentially the half of the volume of void itself . it is also found that in stabilization by exert confining stress the linear phrase will be shorten in the figure of the static triaxial test of specimen , while the initial tangent modulus will be augment . 3
在进行静三轴试验以前先对沥青混凝土试件进行围压稳定，发现在时间足够长的条件下，试件的体积会逐渐缩小，并逐渐稳定在某一定值，其压缩量基本上为其本身孔隙体积的一半；经围压稳定后的试件静三轴试验曲线上的线性阶段明显缩短，而初始切线模量增大。
