Similarly , they not only can represent straight lines precisely , but also can represent quadric curve precisely , such as hyperbola and so on 该曲线与tc - b zier曲线的性质完全类似，此外它既能精确表示直线段又能精确表示双曲线。
It considered the increase of the initial shear stiffness of the surrounding soil with consolidation and unloading and cyclic behaviour of the interface 本文在总结前人研究成果的基础上，改进了反应桩土界面荷载传递性状的双曲线模型。
Using his data from 1830 - 1995 with statistics , the hyperbola and its asymptotes , he estimated 47 new ( species ) of sea monsters are still undiscovered 帕克斯顿利用统计学、双曲线以及它的渐近线，分析他收集的1830年与1995年之间的数据，估计还有47种新海洋怪兽有待我们去发现。
Analyzing their parameter , the paper establish calculating mould for unsaturated stacked loess soil . this mathematic mould simultaneously include force , settlement and time 对双曲线和s lnt的参数进行分析，首次建立了非饱和黄土填土的同时考虑力、变形和时间的计算模型。
By the test of saturated soil and unsaturated soil , this paper enquiry that the stress - strain relationships of compacted soil under one dimensional consolidation is perfect hyperbole 本文通过重塑土(饱和和非饱和)室内试验，探讨了一维情况下压实土的应力应变关系呈现很好的双曲线形式。
