Generally speaking , adsl is a promising broadband access technology . however , while providing adsl services , telcos should take account of all factors deciding the transmission performance of adsl , including subscribers lead - in wire and office wire Adsl是一种很有希望的宽带接入技术，但是在提供adsl业务时，应注意包括用户引入线和局内线等在内的各种影响adsl传输性能的因素。
Linear - complex singularity of stewart manipulator is defined on the basis of the conception of linear complex . according to the pitch of instantaneous screw motion in singular configuration , all singularities of stewart mechanism are classified into three different kinds 引入线几何中线性丛的概念，定义了stewart机构的线性丛奇异，并以奇异时瞬时螺旋运动的节距将奇异分为三类。
Abstract : in this paper , the writers take the pile - plank wall applied in the railway from maga to putaoqin , a feeder railway to neijiang - kunmin railway line , as an example to introduce the structrue , the construction technology , the method of construction and the writers ? experience in construction . this research provides reference for the projects of the same kind 文摘:以六盘水枢纽内昆铁路引入线马嘎至葡萄菁段桩板墙工程为例，介绍了桩板墙的结构特点、施工工艺、施工方法以及施工中的一些体会，可为同类工程借鉴
Four types of constitutive models are provided by the code : linear elastic model , duncan - chung model , nonlinear elastic model taking stress path into account and modified three - element model . contact element is used to simulate possible sliding between soil and structure . with this code , analysis is made concerning the pore pressure dissipation , lateral deformation of the support , ground settlement , bottom heave , and variation in earth pressure and support forces ; both effects of consolidation and coupled effects of consolidation and creep are considered ; furthermore , different combinations of cohesion , permeability and excavation width are elaborated 该程序采用了更合理的开挖荷载的计算方法，可以引入线弹性、邓肯张非线弹性、考虑应力路径的非线性弹性和修正三元件模型等四种本构模型，并在挡墙和土之间设置薄层接触面单元以模拟土体和墙体在开挖过程中可能产生的滑移。
