模块

But if the module does not exist in sys.modules then it is to be added to that dict before initialization begins.

如果 sys.modules 内不存在该模块，它就会在初始化新模块之前把它加入到其中。

本发明公开了一种水轮机筒阀电液同步控制系统，系统由控制阀组、分流马达和配油模块三部分组成，控制阀组油路的输出分别接于六个同步分流马达及相应的六个配油模块。

A change of the specification may be considered small if it affects only a small number of specification modules; to ensure continuity, there must be a direct correspondence between specification, design and implementation modules.

如果一个规格的变化只影响小部分的规格模块，那么这可能会被认为无关紧要；为了确保连续性，在规格，设计和实现模块之间必须有直接对应。

Instantiating the architecture of open CNC system to data communication components Currently, there are four types of describing and expressing software architecture:(1) figure expression drawing with rectangles and directed line segments;(2) path language in module that links traditional programming language module;(3) special software architecture description language combining object-oriented technology with the development experience of traditional program design language;(4) system description language based on components.

instantiating结构的开放式数控系统的数据通信元件目前，共有四种不同类型的描述和表示软件体系：(1)数字表达绘画rectangles定向线段；(2)路径语言模块连接传统的编程语言模块；特殊软件构架描述语言结合面向对象技术与发展经验的传统程序设计语言；(4)系统描述语言的组件。

This paper describes the structure of the seven sections of digital tube that principle, the principle of dynamic scanning, decoding principle, and on this basis, using hardware description language VHDL programming cathode seven sections of digital tube a total of four digital display of the cycle 1 - F, and Quartus Ⅱ platform in the realization of the modules on the timing and top-level simulation of timing simulation module, downloaded to the final realization of the development board of the digital characters and the show rolling.

本文还介绍了七段数码管的结构，显示原理，动态扫描原理，译码原理，以及在此基础上用硬件描述语言VHDL编程实现4位共阴极七段数码管循环显示1-F，并在QuartusⅡ平台上实现了各个模块的时序仿真和顶层模块的时序仿真，最后下载到开发板上实现了数字和字符的滚动显示。

On this basis a design scheme of the database for SCADA based on the component object model is presented, in which the content and background of IEC 61970 standard is introduced first, then some different component model are assayed , then a design scheme of the database for SCADA based on the component object model is presented, the foreground application of SCADA is connected with the database by components.The new model have some advantages: system have disrelation with develop language ,the peculiarity of COM make the system fit in with different apply program developed with different language;(2) the system can be modified and upgraded easily by means of upgrading the component modules;(3) the system can be enlarged easily by means of adding the new component modules without quiet amendment in old system.

为此，本文介绍了一种基于组件对象模型的SCADA数据库系统设计方案，文中首先介绍了IEC61970标准的内容及产生背景，分析了几种不同的组件模型，在此基础上，提出了一种基于COM组件技术的SCADA数据库设计及访问模式，在此模式下根据SCADA数据库不同的功用划分了不同的组件模块，利用组件连接数据库与SCADA前台应用，基于组件技术的SCADA数据库设计有以下一些特点：(1)与语言无关性，COM的特性决定了此系统上可以应用不同语言开发的应用程序；(2)系统易修改及维护，用户可以通过更新组件模块的方式修改及维护系统；(3)系统易扩展新的功能，用户可以通过开发新的组件方式将新的应用与原系统结合，而不用对原系统做很大的修改。

The circuit designing that device happened in the function signal being that a kind of controls owing to ICL8038 , module , AT89C52 monolithic machine under the control of module happened in wave form , lock appearance ring frequency division implement , keyboard , numerical code display , DAC0832 enlarge from precise function of ICL8038 composes capital.

本设计是一种基于ICL8038控制的函数信号发生装置，由ICL8038精密函数波形发生模块、AT89C52单片机控制模块、锁相环分频器、键盘、数码管显示器、DAC0832放大电路构成。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
