By utilizing electromagnetic valve, we can control opening and closing timings of intake and exhaust valves according to the operating situation of the engine. Therefore, the engine performance can be improved suitably in exhaut emission during starting, idle stability, fuel comsumption and engine power, etc. When an engine rotates in the low speed, gas flow is bad and the throttle which adjusts air mass is apt to cause the pumping lose of the engine.

中文摘要传统机械式可变汽门正时系统为分段固定式机构，无法根据引擎转速以及负载变化来提供适当的汽门正时；利用电磁式气阀可根据引擎当时状况控制进排气门的开启与关闭正时以及汽门持续开启正时，因此引擎在冷启动废气排放、怠速稳定性、燃油消耗率以及引擎性能等方面均相当之改善。

It becomes more difficult to manage, integrate and share the control system real-time data when we set up the industrial real-time database because of complicated affair between every department and isomeric character of the system. A three-level-structure model and the method to establish database is provided based on CORBA criterion with its character of being regardless of programming languages, hardware platform and network protocol . A universal real-time database faces multi-system is also set up by learning the distributed criterion, it can realize the request broker , and the application software can visit the database pellucidly ; Thus the power station simulation model can be linked with the control system such as infi90 , ovation and be made use of the control object , a closed simulation and control experiment system is set up. Further more we can build an integrate automatic experiment platform from the simulation object of power plant to the process control and the to SIS.

在创建工控领域实时数据库时，企业各部门间的复杂事务及内部异构性给实时数据的管理、集成和共享带来了一定的困难，根据CORBA规范具有语言无关性、平台无关性和网络协议无关性的特点提出基于分布式计算规范CORBA的三层体系结构模型及建立与维护实时数据库的方法和途径；通过CORBA规范建立面向多个分散控制系统的通用实时数据库，实现数据访问代理，使应用软件可以透明地对实时数据库进行访问、存取、管理；将Infi90、Ovation分散控制系统与火电厂仿真机模型进行有效的互连，以全物理过程仿真数学模型为对象，构建了闭环控制仿真实验研究系统，实现数据的高效连通及管理；进而通过基于CORBA的实时数据库构建一个从火电厂仿真机对象到过程控制设备再到SIS系统的综合自动化试验平台。

Database is the new database that Baidu builds to enact a new rank law, in this database in establishing a procedure, should a lot of people discover how his website didn't appear in Baidu for some time afore not the Description part of capture website, and the website of others appears in afore-mentioned phenomena, from this we can conclude it is OK that Baidu is building new B database get test and verify, the website appeared in Baidu today's phenomenon, we should OK know Baidu has been in for next rank regulation prepares, and it is important that the next will not rank influence of regard as of label of Keywords, Description will not rank influence of regard as of label of Keywords, Description regular Baidu element, even it is met throw the helve after the hatchet, turn and should do new Description to affecting the rank of website keyword with the content of own capture, corresponding do later those who optimize is difficult will increase, and Baidu will let good website appear as far as possible searching an user at the moment, so we are the following heavy name a person for a particular job meets be website oneself content to rise!

数据库算是百度为了制定一套新的排名规律而建立的新数据库，在这个数据库的建立过程中，应该有很多人在前一段时间发现怎么自己的网站没有出现在百度不抓取网站的description部分，而别人的网站出现在上述现象，从这一点上我们可以推断百度在建立新的B数据库应该可以得到验证，网站在百度中出现了今天的现象，我们就应该可以知道百度已经在为下一个排名规则做准备，而下一个排名规则百度将不会把keywords、description标签看做影响排名重要因素，甚至它会完全放弃，转而用自己抓取的内容当做新的description影响着网站关键词的排名，相应的以后做优化的难将会加大，而百度将会尽可能让好网站呈现在搜索用户眼前，那么我们以后的重点将会是网站自身内容的提高！
