对象格式

The outflow fields of a simplified fastback car were studied with numerical methods of different turbulence models and diflerent discretization scheme s with the CFD code STARCD.

以简化的直背式轿车模型为研究对象，以商用计算流体力学软件STAR-CD为工具，应用不同的湍流模型和离散格式对轿车外流场进行了数值模拟，通过与试验结果的对比，研究了湍流模型和离散格式对直背式轿车外流场数值计算精度的影响，同时对SIMPLE算法及其两种修正方法PISO和SIMPISO算法的计算精度进行了比较。

With the guidance of object-oriented idea and the theory of flexible software, report is described as a three-layer model that consists of the origin-data layer, the data-processing layer and the format layer. The format of report is separated from its data, which makes the data variable, the format fictile and the processing of data modularized. The problem of fixed report template and data is solved. Users can adjust reports format and content easily at any moment. The data of report are dynamic and can be refreshed when needed.

它以面向对象的思想和柔性软件系统理论为指导将报表描述为包含原始数据层、数据处理层和格式层的三层结构模型，将报表数据与格式分离，使报表数据变量化、报表格式可塑化、数据处理模板化，从而解决了报表模板和数据固化的问题，使用户可以随时根据情况需要简捷方便的调整报表的格式和内容，并可以实现报表数据的动态赋值和自动刷新。

See the section called "Object storage format" for the details of the object formatting and SHA1 calculation.

This technique realizes fast reading of XTF format file with mass data and also provides the technical reference for format transformation and data processing of other well logging data formats.

在对ECLIPS 5700数控测井系统XTF文件格式分析的基础上，基於內存映射文件技术，採用面向对象的方法创建了XTF文件数据读取类，实现了大数据量XTF文件数据的快速读取，也可为其它格式测井数据的格式转换和数据处理提供技术参考。

To prevent an object from being printed on a sheet, select the object, click Object on the Format menu, click the Properties tab, and then clear the Print Object check box.

如果不想将某个对象打印到报告上，选定该对象后，再选择"格式"菜单中的"对象"命令，在"属性"选项卡内清除"打印对象"复选框。

Practically all Python objects have a string presentation either evaluatable from repr( or '', or printable from str. The print statement automatically invokes the str function for an object. This gets even better. When you are defining your own objects, there are hooks for you to create string representations of your object such that repr and str (and '' and print) return an appropriate string as output. And if worse comes to worst and neither repr or str is able to display an object, the Pythonic default is at least to give you something of the format

事实上，所有的Python对象都有一个字符串表示形式（通过repr函数，''或者str函数来展现）。print语句自动为每个对象调用该对象的str方法，这种机制的一个额外的好处就是在你定义你自己的对象时，你可以利用这种机制定义repr(，str或者''或者print来为你的对象创建一种字符串表达形式，它可以在被调用时返回适当的字符串描述信息，这样即使在坏的不能再坏的情况下，repr或者str起码可以给你返回一个对象的信息，Pythonic方式的默认做法是起码给你返回想如下格式的信息

The combinatorial coding number of 64 codons to encode 20 amino acids and the terminate code is very huge.

用N个密码子对m个编码对象进行编码的编码格式是m元N维空间中的一个顶点。64个密码子对20种氨基酸和终止密码子进行编码格式的组合编码数是一个十分巨大的数字。

For each name string in the format, which is enclosed in parentheses after the % character that denotes the start of a format item in the format string, Python calls the get-item method of the righthand-side mapping (e.g., the special method _ _getitem_ _, when the righthand side is an instance object).

因为对格式中的每个名字字符串格式，它被放在刮弧中，在格式串中跟在指示格式项开始的'%'字符的后边，Python将调用右边映射的get-item方法。(举例来说，当右边是一个实例对象的时候，是特殊方法 _ _ getitem _ _ )。

The groundwork of this text is as follows:In understanding the graphic presentation characteristic of the construction drawing of the building, foundation of content. At building the semantemes of construction drawing, building construction drawings understanding tactics and content gone on detailed analysis understanding. Have laid a good foundation for the following understanding of the construction drawing; According to the expression characteristic of the construction drawing, utilize the technology of OOP, Adopt C ++ language and draw the level models of fire control feature; It carries on deep analysis to DXF file format give and a method of read DXF file. On the basis of reading DXF file and familiar with understanding to the form of DXF file, study to the pattern recognition methods of fire control facility.
