非线性双曲线 meaning in English

nonlinear hyperbolic

The soil plug has an important effect on the pile driveability , and the pile diameter has an important effect on the property of soil plug , too . then the plugged effect judging method and nonlinear model of soil plug of the large ( super large ) diameter , super length , deep penetration pile have been established . hyperbolic model of soil plug was also proposed to calculate the inside static resistance
3 .土塞对大直径、超长桩的可打入性有重要影响，而桩径大小直接影响土塞特性，本文建立了大直径（超大直径）、超长、深贯入桩土塞闭塞效应判断方法和土塞非线性双曲线计算分析模型，并提出了“内侧极限摩阻力动态分布”模式。
