Based on the analysis of the problems which the Inventory Management of foreign and abroad faced, and considered the theory of Supply Chain, we can analysis the threatens and the reasons bringing by the information requiring of mutating and expanding phenomena -"Bull-whip Effect" in the Inventory Management of chain environment, and can further bring about the policy to solve it. We studied the three new policies for Supply Chain Inventory Management, and VMI realizes the cooperative management between the superior and subordinate knot of supply chain in the enterprise; Multi-grade Management realizes the optimization of the supply chain inventory management from full view; but JMI is the inventory management form of risk sharing, its stress the jointed within the supply and demand at the same time and constitute the inventory plan, to promote every managers (vender, manufacturers, distributors) of the SCM are thinking the harmonious with them, to keeping the accordant anticipate for the inventory manager"s inquest between two conjoint enterprises.In view of VMI stratagem"s fine pragmatism and operation, on the base of understanding VMI, combine the conceivable four assorted relationship in the real supply chain between the conjoint enterprises.

论文在分析国内、国外库存管理所面临的问题的基础上，结合供应链一体化理论，对供应链环境下库存管理中出现的需求信息变异放大现象--即&长鞭效应&的危害及其产生原因进行了分析，在此基础上进一步提出了解决&长鞭效应&的措施；重点研究了实现供应链库存管理的三种新策略，其中，供应商管理库存实现了供应链上级与下级节点企业之间的协作管理；多级库存管理是从全局的角度实现了供应链库存管理的优化；联合库存管理是一种风险分担的库存管理模式，它强调供需双方的同时参与，共同制定库存计划，使供应链中的每个库存管理者(供应商、制造商、分销商)都从相互之间的协调性考虑，使得供应链相邻两节点企业之间的库存管理者对需求的预期保持一致基于VMI策略的良好的实用性和可操作性，在理解VMI概念的基础上，结合实际供应链中节点企业间可能出现的四种组合关系，相应地提出四种概念性架构，用以表达：VMI系统的内部结构；VMI系统与节点企业内部管理系统的接口关系及两类系统的关系；VMI系统与节点企业间的信息共享与转换，如库存信息在供需之间的传递、加工等具体过程。

The development of animation as the progress of mankind in the new century painting of the logo, the inheritance of human culture and biological organism also update it regularly, the human imagination as an extension of time and space changes, the modern design gradually from 2D to 3D and 4D (that is, We often hear the two-dimensional space, three-dimensional space, four-dimensional space) space extension of the art of color design and science and technology as we show a wealth of space symbol, is also given to the human meaning of a new life.

动画片的发展作为新世纪人类绘画进步的标志，人类文化的继承也和生物机体的不断更新有关，人的想象随着时空的变化而延伸，现代设计也逐步从2D到3D和4D（也就是我们常听到的二维空间、三维空间、四维空间）空间延伸，色彩设计中的艺术化和科技化为我们展现了丰富的空间符号，也赋予人类新的生活内涵。

In the paper chapter one introduces the background and significance about designing the GPIB controller based on Ethernet. Chapter two describes the whole design idea of the controller, at the same time, introduces ENET protocol, TCP/IP protocol and other associating protocols. Chapter three discusses the hardware and firmware design of ENET-GPIB controller. Chapter four describes how to realize the dynamic link library functions and VISA functions of the controller. Chapter five collogues the trend of ATS. Chapter six summaries the design and give some experience and advice about scientific research.

First, analysized from objective angle, the causes of study holdbacks are related to the following three factors .The first factor is about textbook. The teaching aims and demands, teaching contents don't correspond with teaching time .Otherwise, the textbook itself is too difficult for the students. The second factor is about teachers. Teachers' ideas of education are not regular. Knowledge structure is not so reasonable . Teachers' teaching abilities should be improved. The third factor is that school is short of experimental resources. Second, analysized from students' subjective angle, the cause of study holdbacks have four types .

首先从客观角度分析，学生化学学习障碍的产生与如下三个因素有关：一是教材的原因，它包括培养目标要求、教学内容与教学时数不相匹配，教材本身过难；二是教师的原因，这一点主要体现在教师的教育思想不够端正，知识结构不尽合理，施教能力有待提高等三个方面；三是学校的原因，主要是指实验资源过于匮乏。
