Although these languages can issue operating system commands and use generic interfaces with some effort , a scripting language such as rexx is designed specifically to do just that 虽然这些语言通过一定的努力也可以发出操作系统命令以及使用一般的接口,但rexx之类的脚本语言是专门为此而设计的。
Rexx glues together existing codewhether this code comes in the form of operating system commands , interface apis , services , widgets , objects , functions , interfaces , or toolsand leverages it for greater productivity Rexx将现有的代码粘合在一起不管代码的形式是操作系统命令、界面api 、服务、小配件、对象、函数、接口还是工具并利用这一点获得更大的生产率。
The following example uses a sqlcmd statement to create an output file called testoutput . txt , executes two transact - sql select statements along with one operating system command to print out the current directory 以下示例使用sqlcmd语句创建名为testoutput . txt的输出文件,并将两个transact - sql select语句与一个操作系统命令一起执行(以打印当前目录) 。结果文件包含
Under the circumstances , and assuming that the high credibility that hong kong s exchange rate system commands is sustained , there is no reason why the fixed exchange rate of the hong kong dollar should be unduly affected by the movements , if any , of the renminbi exchange rate 在此情形下,并且假设本港汇率制度一贯的高度公信力继续得以维持,即使人民币汇率有任何变动,港元固定汇率也不应受到不必的影响。
Electromotor joins with high efficiency selected water pump , scm ( single chip micyoco ) control system commands water pump according to cooling water temperature which substitutes traditional strap - driving mechanism pump and forms tael - level intellectualized control cooling system combining with electromotion control of cooling fan . consequently it realizes that water pump and fan autoregulate with engine working status and assures t hat cooling water temperature keeps in the best range all the time and advances the reliability of engine working and realizes exact control of cooling water temperature in deed 选用高效率水泵与电机联接,改由单片机控制系统根据冷却水温控制水泵的工作,代替传统的皮带带动的机械水泵,结合冷却风扇的电动控制形成两级智能化控制的冷却系统,从而,实现了水泵和风扇转速随发动机工况变化的自动调节,真正实现了冷却水温的精确控制,保证了冷却水温始终保持在最佳范围内,大量减少传热损失降低油耗,并提高了发动机工作的可靠性。
This text describes the project basic principle and system structure and capabilities of production equipment for mechanism and electric , according as require of blast furnace automation , analyzes the chemical reactions in blast furnace by principle , according as mass and energy balance principle build on process models and technology calculate , according as process optimization principle build on process system optimization models , and technology calculate , as one time , expert system command any model . the expert system contains a knowledge base , which already represents the concentrated know - how of blast furnace operation , gathered from many installations world - wide 本文在介绍了项目的基本原理和系统构成以及相关的生产工艺的基础上,根据高炉过程优化的要求,从机理上分析了高炉冶炼过程的化学反应,并依据质量能量平衡原理建立了工艺模型和技术计算,按照优化原理建立了过程系统优化模型,并在专家系统的调度下协调工作。系统还包括知识库,它总结了普通高炉操作的理论知识和控制理念,同时,结合钒钛磁铁矿的冶炼知识,形成具有攀钢冶炼特点的知识库。
