当涉及大量商业逻辑项目的时候,我们需要考虑什么?如何分离用户界面和后台操作？如何避免将商业逻辑混淆于一般的流程控制中？作为企业信息系统， 就需要考虑很多类似的问题。
源源不断的客户新需求, 要进行功能修改和扩充, 但是因为程序的高耦合，改动将变得非常困难，导致项目成本何风险增加。 而且，往往维护人员与开发人员不是同一个人， 即使有详尽的文档，也很难理清程序里纵横交错的联系。 所以贯彻Model-View-Controller（MVC）模式的设计， 在设计阶段首先杜绝此类问题, 是一个非常好的方法。
When it comes to a lot of business logic project, we need to consider what is? How to separate the user interface and background operation? How to avoid confusion in the business logic of the general process control? As an enterprise information system, we need to consider many similar problems. A steady stream of new customer needs, to conduct functional modification and expansion, but because of the program' s high coupling, modifications will become very difficult, resulting in an increased risk of any project costs. Moreover, maintenance personnel and developers are often not the same person, even if there are well-documented, it is difficult to sort out the program criss-cross linked. So implement Model-View-Controller (MVC) design pattern, first at the design stage to prevent such problems is a very good way. (2013-08-10, Java, 603KB, 下载2次)

DHCP（Dynamic Host Configuration Protocol，动态主机配置协议）是IETF为实现IP的自动配置而设计的协议，它可以为客户机自动分配IP地址、子网掩码以及缺省网关、DNS服务器的IP地址等TCP/IP参数。了解DHCP工作过程可以帮助我们排除有关DHCP服务遇到的问题。DHCP 协议是基于UDP层之上的应用，本文结合抓报所得数据分析DHCP协议实现原理
DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is the IETF protocol designed for automatic configuration of IP for the client, it can automatically assign the IP address, subnet mask, and default gateway, DNS server IP addressand other TCP/IP parameters. Understanding of the DHCP the work process can help us to rule out problems encountered about DHCP service. The DHCP protocol is based on the the UDP layer on top of the application, combined with a grasp reported income data analysis DHCP protocol implementation principle (2012-12-07, Unix_Linux, 312KB, 下载4次)

对广大供电企业来说，用户功率因数的高低，直接关系到电力网中的功率损耗和电能损耗，关系到供电线路的电压损失和电压波动，而且关系到节约电能和整个供电区域的供电质量，这是众所周知的道理。提高电力系统的功率因数，已成为电力工业中一个重要课题。文中简要集中探讨了影响电网功率因数的主要因素以及低压无功补偿的几种实用方法，和确定无功补偿容量从而提高电力系统功率因数的一般方法。
For the majority of power supply enterprises, the level of user power factor, is directly related to the power loss and power loss in the power grid, related to the voltage of the power supply line losses and voltage fluctuations, but also to save energy and supply area for electric quality, this is a well-known truth. Improve the power factor of the power system, the power industry has become an important topic. Briefly several practical approach focuses on the main factors affecting the grid power factor and low voltage reactive compensation, and determine the reactive power compensation capacity of the general method to improve the power factor of power system.
