As a foundation pit excavating support technology which is easy and celerity to implement , safe and less cost , soil nailing is getting more and more application to deep excavation construction . however , soil nailing cannot be used in very soft soil or for cases which deformation of the soil nailing has to be strictly limited . to cope with these more difficult situations , compound soil nailing , i . e . a combination of soil nailing with soil - cement mixing piles or mini pile , is recently developed 土钉支护作为一种经济可靠、快速简便的挡土技术,已在深基坑开挖施工中得到越来越多的应用,但单纯的土钉支护技术不能用于淤泥质土,砂土等不良土层及对变形控制严格的情况,所以近年来又发展了土钉与搅拌桩、微型桩等支护相结合的复合型土钉墙支护形式。
Container transportation is a kind of traffic mode , which include the characteristics " celerity , safety , high quality and cheapness " . it has been taken into effect in ocean shipping for about 50 years . from 1970s , container transportation had been used in several area , and it was 1976 that our country began to test this kind of traffic mode in the changjiang river 集装箱运输作为一种“快速、安全、优质、价廉”的运输方式，在海运中发挥作用已经有近50年的历史了，上世纪70年代开始，集装箱货运方式在一部分地区的内河也得到了采用，而我国在1976年也开始了在长江水系试验集装箱运输方式。
Nowadays , with the development of economic globalization and informative globalization , electronic commerce is popular with these advantages of low price , high efficiency , celerity and convenience , which has gone beyond the limitation of zone and time . therefore , more and more enterprises and users choose to use it 在经济全球化和全球信息化迅速发展的今天,电子商务以不受地域时间限制、成本低、效率高、快速、方便,受到越来越多企业和用户的欢迎,在世界范围内保持着快速、持续发展的态势。
In this paper the research object is new model alternating current servo system . according to the request that was the static state - dynamic state precision and the celerity of response brought forward by task book , aimed at the bad circs of large inertia variety load and the sway of launch flat , we made deep research 本文以新型交流伺服系统作为研究对象，依据设计任务书所提出的静态、动态精度和响应快的要求，针对大惯量、变负载和力矩干扰等恶劣情况之下的伺服控制问题进行了深入研究。
Nowadays with the great development of the internet , email has been becoming more and more important in human ’ s life for its celerity and convenience . web surfers are accustomed to communicate through emails , and have to deal with bulks of emails everyday . therefore , it is urgent to classify emails into folders automatically 目前,随着网络的发展,电子邮件已成为人们生活快速、便捷的重要通信手段之一,人们通过电子邮件的往来日益频繁,每天都要处理大量的邮件,所以迫切需要对邮件进行分类处理。
The transport must be first developed , so can the economic progress . chongqing ' s southeast district , which lies in the hinterland of wuling mountain area , is contiguous to hubei province , hu ' nan province and guizhou province . lt is the most convenient over - land passage that chongqing lead to southeast coastland . chongqing serve as the economic center of the changjiang river ' s upriver and transport junction , the area which is transport inconvenience is in east of chongqing . the big alleyway which chongqing to east is being celerity form along with the building and item radicating of yuhuan railway , wanyi railway , hurong highway , yuchang highway 渝东南地区地处武陵山区腹地，与湖北、湖南、贵州三省接壤，是重庆市通往东南沿海最便捷的通道，作为长江上游经济中心和交通枢纽的重庆市，其交通最为困难的部分在东部，随着渝怀铁路、万宜铁路、沪蓉高速公路、渝长高速公路的建设和立项，重庆市向东的大通道正在快速形成之中，这对重庆市向东部(长江三角洲和珠江三角洲)全方位开发，促进经济发展具有重要的战略意义。
Paper aims at the theory problem of exact celerity machining design which is realized urgently in special shaped products , solves mathematics model of similar forming plastic stream , recurring to modern conformal mapping fruit , builds die mathematics model and optimized function equation of arc square product in precision extruding / drawing , establishes theory model for precision celerity shaped die of cad / cam integrative constitution 摘要本文针对亟待实现的挤压（拔制）异型材模具精密快速加工设计理论课题，借助于近代共形映射理论研究成果，求解了异型材挤压（拔制）模具相似成形塑性流动的数学模型，建立了圆角方型材精密挤压（拔制）模具模腔数学模型及其优化函数方程，建立了为实现模腔精密快速的cad / cam一体化的理论模型。
The new ways in moral education must be on the way . this study reveal : the speedy effective , celerity , convenience and unique intercourse of the network coincide with the demand of the young students who look after illusion and independence . under the network surrounding , the moral mainstream of our country students is healthy and upword 调查表明：网络高效、快速、方便、独特的交流方式与当代青少年学生偏于好奇、乐于幻想、追求独立的要求相吻合；网络环境下我国青少年学生的思想品德主流是积极、健康、向上的，德育工作的成绩是主要的，经验不可否认。
