Firstly,the development length is the summation of transmitting length and flexural bond length.
首先分析了高强钢绞线在先张预应力构件中的粘结锚固性能,将预应力传递长度与弯曲粘结长度之和定义为延伸长度,给出了延伸长度的计算公式。
A model for ferroelectric nanowire calculation was established based on the Landau-Ginsburg-Devonshire(LGD)theory and a new method to obtain the extrapolation length was developed.
在Landau-Ginsburg-Devonshire(LGD)理论的基础上,建立了铁电纳米线的理论模型,并通过与第一原理计算结果的对比,建立了一种获取外延长度的新方法。
