选择步进电机时，首先要保证步进电机的输出功率大于负载所需的功率。而在选用功率步进电机时，首先要计算机械系统的负载转矩，电机的矩频特性能满足机械负载并有一定的余量保证其运行可靠。在实际工作过程中，各种频率下的负载力矩必须在矩频特性曲线的范围内。一般地说最大静力矩Mjmax大的电机，负载力矩大[1 ]。
选择步进电机时，应使步距角和机械系统匹配，这样可以得到机床所需的脉冲当量。在机械传动过程中为了使得有更小的脉冲当量，一是可以改变丝杆的导程，二是可以通过步进电机的细分驱动来完成。但细分只能改变其分辨率，不改变其精度。精度是由电机的固有特性所决定。
选择功率步进电机时，应当估算机械负载的负载惯量和机床要求的启动频率，使之与步进电机的惯性频率特性相匹配还有一定的余量，使之最高速连续工作频率能满足机床快速移动的需要。

Business logistics
Logistics as a business concept evolved in the 1950s e to the increasing complexity of supplying businesses with materials and shipping out procts in an increasingly globalized supply chain, leading to a call for experts called supply chain logisticians. Business logistics can be defined as "having the right item in the right quantity at the right time at the right place for the right price in the right condition to the right customer", and is the science of process and incorporates all instry sectors. The goal of logistics work is to manage the fruition of project life cycles, supply chains and resultant efficiencies.
In business, logistics may have either internal focus (inbound logistics), or external focus (outbound logistics) covering the flow and storage of materials from point of origin to point of consumption (see supply chain management). The main functions of a qualified logistician include inventory management, purchasing, transportation, warehousing, consultation and the organizing and planning of these activities. Logisticians combine a professional knowledge of each of these functions to coordinate resources in an organization. There are two fundamentally different forms of logistics: one optimizes a steady flow of material through a network of transport links and storage nodes; the other coordinates a sequence of resources to carry out some project.
[edit]Proction logistics
The term proction logistics is used to describe logistic processes within an instry. The purpose of proction logistics is to ensure that each machine and workstation is being fed with the right proct in the right quantity and quality at the right time. The concern is not the transportation itself, but to streamline and control the flow through value-adding processes and eliminate non–value-adding ones. Proction logistics can be applied to existing as well as new plants. Manufacturing in an existing plant is a constantly changing process. Machines are exchanged and new ones added, which gives the opportunity to improve the proction logistics system accordingly. Proction logistics provides the means to achieve customer response and capital efficiency.
Proction logistics is becoming more important with decreasing batch sizes. In many instries (e.g. mobile phones), a batch size of one is the short-term aim, allowing even a single customer's demand to be fulfilled efficiently. Track and tracing, which is an essential part of proction logistics—e to proct safety and proct reliability issues—is also gaining importance, especially in the automotive and medical instries.

6. 求2篇关于区域物流系统的英文文献，并有中文翻译
20世纪 80年代以来，在区域经济一体化趋势下，区域经济合作成为一种普遍的经济现象，区域问物流、商流、信息流、资金流等不断涌现，物流活动日趋频繁。如何减少物流距离、缩短物流时问、降低物流费 用，成为区域经济协调发展亟需解 决的问题。在这个背景下，区域物流 成为现代物流发展中的一个重要领 域，受到全世界的广泛关注 ，各国都 十分重视区域物流的研究。进入21 世纪，我国各级政府、产业界和理论 界高度重视并切实推进区域物流发 展，促进商品及各种要素的高效流 动和配置优化。 为实现区域经济社会的可持续 发展，要对区域物流进行统筹协调、 合理规划、整体控制，实现区域物流 各要素的系统最优 目标。区域物流 涉及物资在区域内的实体流动、区 域间的货物集敞过程 ，重点解决一 个区域内的物流系统优化 问题 ，保 障整个区域的物流活动满足生产活 动、消费生活的需要，提高区域经济 运行质量，促进区域经济协调发展。 区域物流中的“区域”是具有特 定经济意义的地区范围，电可称之 为经济区域。区域物流作为区域经 济活动的重要组成部分，是区域功 能得以发挥的有力支柱，体现区域资源的合理配置和有效利用，满足区域经济社会可持续发展的战略需要此，区域物流的价值取向是区域经济社会的协调及可持续发展。
区域物流作为区域经济社会的 个子系统，涉及区域物资的运输配 送、仓储保管、现代包装、装卸搬运、流通加工、信息处理等领域，其产生 和发展是随着社会分工协作和地区 经济专业化的发展而发展的。第一 次社会大分工后，自给自足的自然经 济仍占统治地位，商品生产和交换的 比重很小，地区间的联系很弱，一般 只在农业部落和游牧部落之问存在 零星的、分散的物资流动。第二次社 会大分工后，手工业、矿业、小规模原 材料工业、简单制造业等应运而生， 商品生产和交换不断发展，但是受交 通条件、运输条件等经济基础的制 约，物资流通范围较小。第三次社会 大分工后，出现了专门从事商品交换 的商人，商品交换向纵深发展，物资 流通日趋频繁，一个或少数几个条件 优越的地区与其他地区开始分化，产 生了一个或几个区域性的、以条件优 越地区为中心、周围地区为外围的二元结构。随着商品经济的发展，中心区经济迅速发展，对资源的需求大幅度扩张，与其他地区之间的物流联系不断加强；外围地区也逐渐得到开发 ，成为区域的次级中心，形成主中心、次中心相互衔接的多核结构区域经济。 在经济社会发展过程中，不删中心区之间的外围地区逐渐被纳入中心区的物资流通循环中，区域经济在空间上实现一体化。区域物流被融入一个统一而又相互依赖的体系之中，区域物流发展呈现网络系统化态势，深刻影响着区域工农业生产、居民生活和经济社会的正常运行。
区域经济理论强调区域经济增
长需要区域 内和区域之间的物流、商 流 、信息流、资金流。没有高效的物 资流动，就不会有增长的极化和扩散 效应，梯度推移也就不会实现；没有 物资的合理流动，就不能促进区域经 济社会的可持续发展。另一方面，区 域经济理论可以应用于物流产业的 定位分析，指导区域物流发展。例如，
将增长极理论应用到区域物流规划， 可集中在以下几个方面：物流基础设 施建设，应注 资源增长极”、“产业 增长极”和“城市增长极”有机结合， 避免重复建设；物流园区的建设，应注重增长极的诱发效应、极化效应、 渗透效应和扩散效应；重点物流园区的建设，应注重“增长极核效应”。
Since the 1980s, the trend of regional economic integration, regional economic cooperation has become a common phenomenon in the economy, asked the regional logistics, business flow, information flow, capital flow, and other emerging services, logistics activities have become more frequent. How to rece the distance between the logistics, logistics shorten the time to rece logistics costs, as a regional economic coordinated development of the urgent need to resolve. Against this background, to become the regional logistics of modern logistics development in an important field by the world wide attention, both countries attach great importance to regional logistics. In the 21st century, our country at all levels of government, instry and the community attached great importance to theoretical and practical logistics to promote regional development and promotion of commodities and various elements of the high-performance mobile and optimize the configuration. To achieve regional sustainable economic and social development, it is necessary to carry out the logistics of the regional co-ordination, planning and reasonable, overall control, regional logistics elements of the system optimal goal. Regional logistics supplies in the region involving physical movement of goods between the regional-open process, a focus on the region's logistics optimization system to protect the region as a whole to meet the logistics activities of the proction, consumption needs to increase regional economic operation quality And promoting the coordinated development of regional economy. Regional logistics of "regional" is a particular economic significance of the area, electricity can be regarded as the regional economy. Regional economic activity as a regional logistics an important part of the region is able to function effectively play the pillars of the region reflect the rational distribution of resources and effective use to meet the region's economic and social sustainable development strategy needs this, the value of regional logistics in the region Economic and social co-ordination and sustainable development.
As a regional logistics sub-regional economic and social systems, involving regional distribution of goods transportation, warehousing custody, modern packaging, handling transportation, circulation processing, information processing and other fields, the emergence and development of the social division of labor with regional economic collaboration and professional And the development of development. The first division of social, economic self-sufficiency of natural still dominant, commodity proction and exchange of the proportion of small, weak linkages between the region, generally in the agricultural tribes of nomadic tribes and asked the existence of sporadic, scattered supplies流动. The second major social division of labor, handicrafts, mining, small-scale instrial raw materials, simply came into being, such as manufacturing, proction of goods and the continuous development of the exchange, but subject to traffic conditions, transportation and other economic conditions on the basis of constraints, the smaller the flow of goods and materials . Third social division of labor, there have been dedicated to the exchange of commodities traders, commodities exchange in-depth development, the flow of goods is becoming more frequent, or a small number of excellent conditions for the region and other parts of the division began to proce one or more regional To excellent conditions for the region as the center for the area around the periphery of the al structure. With the development of commodity economy, the central area of rapid economic development, the demand for resources to expand substantially, and other parts of the link between the continued strengthening of the logistics; outlying areas have graally been developed as a regional sub-centers, to form the main center Center at the interface between the multi-regional economic structure. In the economic and social development, do not delete the central area between the outlying areas have been graally integrated into the central area of the flow of goods and materials circulation, the regional economic integration in space. Regional logistics and be integrated into a unified interdependent system, a network of regional logistics development trend of systematic and profound impact on regional instrial and agricultural proction, living and the economic and social functioning.
Regional economic theory emphasizes the importance of regional economic growth
Chang needed in the region and between the regional logistics, business flow, information flow, the flow of funds. No efficient movement of goods, there will be no growth and spread of polarization effect, evolution will not be realized; no rational flow of goods, will not be able to promote regional economic and social sustainable development. On the other hand, the regional economic theory can be applied to the location of the logistics instry analysis, to guide the development of regional logistics. For example,
Growth pole theory will be applied to the regional logistics planning, can be concentrated in the following areas: logistics infrastructure construction, resources should note growth "," growth instry "and" urban growth "organic integration in order to avoid plication; Logistics Park The building, should pay attention to the growth inced by the effect of the polarization effects, effects of infiltration and proliferation effect; focus on the logistics park, should focus on "core growth effect."
