MELINETS系统自动短信发送催还通知的实现

针对当前许多主流的图书馆数据管理系统在催还上普遍存在自动化程度不高、不能预先告知、催还不及时等不足,文中提出引进时下流行的GSM-Modem短信平台.通过自主开发与图书馆数据管理系统的接口程序,实理自动提前从图书馆管理数据库中提取将要超期的读者信息,然后提交给GSM-Modem短信平台自动发送.这样一方面减轻了工作人员的工作量,一方面使得催还变得更加人性化.同时,通过自主开发,可以用较少的费用实现图书馆数据管理系统的功能升级.     

油田注水站控制系统设计

采用西门子S7-200可编程控制器和MM430变频器,通过PID控制实现了油田恒压注水,把电力电子高新技术用于油田注水生产,实现了注水系统自动化,优化了油田注水工艺,降低了注水系统的能耗,具有重要的节能意义。     

当代国内领先水平的油田及其培训

1996年8月16日,石油天然气总公司教育指导委员会主任黄凯等一行4人,考察了塔里木盆地北部边缘库车县境内的东河塘油田,认为这个油田已经出色地实现了总公司提出的“一少四高”的要求(油井少、单井产量高、管理水平高、自动化程度高、经济效益高),是我国目前一个具有90年代国际水平的样板油田。这表现为:1.全部工艺和技术设备不拘一国地采用当代国际先进水平。哪个国家在哪方面属世界一流就采用哪个国家的。如自动化控制系统选用世界一流的 MIPS 计算机工作站,注水系统引进了世界最大的40MPa 高压注水泵等。2.自动化控制系统先进。整个油田只有一个

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
