查询词典 format object

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

A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD. Research indicated that this system can be applied in reverse measurement to the dimensions of 2-D object complex edge.

对机器视觉二维反求测量系统进行了研究，以实现二维复杂平面边缘尺寸的数字化录入；采用虚拟网格技术实现大场景下的测量标定；利用双CCD分区域获取图象，通过设置规则参照物、数据拼接等数据处理提高测量精度；提出了利用8-链码的&链差&确定转折点，用&变长度虚拟直线&判断线型实现图形矢量化的方法；数据输出采用通用的DXF文件格式实现与CAD软件的接口；研究结果表明，该系统能够应用于二维复杂平面边缘的反求测量。

That example contained logic in the format of a Python object and new pages in the format of page templates.

这个例子包括Python形式的对象和一个页面模板形式的新页面。

In addition to the universal directives described in this chapter, each object file format can optionally supply extra directives in order to control particular features of that file format.

除了本章所描述的通用指令，每一种目标文件格式都可以选择性地使用附加指令来控制文件格式的一些特性。

The format string used to format the replacement sequence, or a formatter function, function object, or expression.

用于对替换序列进行格式化的格式化串，或是一个格式化器函数、函数对象或表达式。

In this article both stereo vision and line2laser scan sensor are integrated to CMM,according to this measuring system the bound2 aries or outlines of object are obtained by stereo vision and the ostensible data of object are achieved by line2laser scan sensor. Information fusion of multi2sensor can be utilized to segment 3D data、to abstract the geometry characteristic of the object、to construct the object modeling.

将立体视觉和线激光扫描传感器集成到三坐标测量机下，由立体视觉来获得物体的边界或轮廓信息、线激光扫描传感器获得物体表面的三维数据，利用多传感器的信息融合技术对三维数据进行分割，提取被测物体的几何特征，并在此基础上构建物体模型。

Under the cloner object's attribute settings change the mode to object and drag the matrix object into the object dialog box.

在cloner物体的属性设置中将模式改为object，然后拖拽matrix物体到当前面板中的物体对话框中，并将other选项卡空的是否可见勾选上。

In this thesis, we apply Coulomb's law and propose an external force to overcome the problem of traditional ACM that can not capture the cavities of an object. Assume that each node of a snake has its own electric charge, and the object boundary has opposite electric charge. Then object boundary will attract the nodes of the snake. This helps the contour easily to move to the object boundary.

本论文中，我们运用库仑定律的观念，提出了一个运用局部引力作为外力的方法，用以克服传统主动性轮廓模型在凹面处收敛不佳的缺点；假设物件边界带电，而主动性轮廓模型的结点带与物件边界相异之电荷，则物件边界会吸引著主动性轮廓模型各结点，使得模型曲线更容易靠近物件边界。

Clustering divides a set of physical or abstract object into several clusters that constitutes for the similar object, the object in the same of cluster are similar each other, but the object in the different cluster are dissimilitude each other.

聚类分析就是将一组物理或抽象对象，分组为类似对象组成的多个簇，在同一个簇中的对象彼此相似，不同簇中的对象彼此相异。

Digital image processing technology,the present reseach level about image alarm system is to separate eyewinker from monitoring image,and to judge whether the eyewinker is harmful according to the size of the area of object,this method is imprecise and suspectable.The image recgnition alarm system isan apply on image processing technology.when a foreign object enter monitoring place,we will segment、measure object,and analysis、judge through proportion characer or invariant monent.the result of the parameter will decide whether the eyewinker is harmful,if the object is harmful ,system will auto-startalarm device.

而本设计的主要特点是基于了数字图像处理技术，目前传统图像报警系统的研究水平是将异物从监控图像中分离出来，然后依据异物面积的大小来判断异物是否有害，它对异物有害的判断十分不准确，这种判断结果的有效性是很值得怀疑的；针对于这些弊端，本课题在数字图像处理技术上的应用是对监控场所进行全景监控，如有异物进入，对异物进行分割、测量，从不同的角度进行了分析和判断，进而决定异物是否有害，若满足场景所规定的有害条件，则启动报警装置，发出报警信息。

For the head-teacher of the class said that I had seriously broken the school rules,which led me to a three-day suspend class.

为什么呢？因为我的班主任说我严重的违反了校规，于是让我停课三天。

Many of them believe that the conversion of thousands of working-class folk in England spared that nation from the mass carnage and the tyranny that came with the revolution in France.

他们之中有许多人相信，在英国数以千计的劳工阶级之悔改信主使英国免於遭受如法国大革命所造成的大屠杀和专制暴政。
