提取信息

In the CAD system for progressive dies, the method is introduced to automatically generate geometric models of stampings through inputting the product drawings by AutoCAD and picking-up the entity information from DXF files and programming with ObjectARX and C＋＋ language, at the same time, generating algorithm of close contour lines and unidirectional chain-table structure are used to express the models of stampings, the class and direct judgment of contour lines are realized and the entity existing side is judged by analytical geometry, which efficiently solves the problem of automatic input of drawings of stamping and providing information of process planning and mold design.

在级进模CAD系统中，将产品的图形信息以AutoCAD直接绘图形式输入到计算机中，从AutoCAD的图形交换文件中提取信息，采用面向对象的二次开发工具ObjectARX和C＋＋语言编写接口程序，并通过封闭轮廓的生成算法自动生成冲裁零件的几何模型，且用单向链表的形式加以表达，同时对冲裁零件图形的轮廓进行分类与走向判定，采用简单的解析几何方法对实体存在侧进行判定，有效地实现了零件图形的自动输入，为级进模CAD系统的工艺计算和模具工作部分的设计等提供了必要的信息。

It explores the research on basic representation, analysis and synthesis methods of signals, and the basic approaches and implementation algorithms of extracting information from signals.

它探索信号的基本表示、分析和合成方法，研究从信号中提取信息的基本途径及实用算法，提高信号在传输存储中有效性和可靠性。

So it can effectively extract information from the signal and carry outmultiscaled detailed analysis through dilation and shift operations.

Using a tool like Ethereal, you can listen to the HTTP channel and extract the messages.

像Ethereal使用的工具，您可以收听到HTTP通道和提取信息。

If it isn't, it's called a cache miss and the computer has to fetch the information by accessing the main memory or hard disk, which is slower.

如果 CPU 没有提取信息，那么称为高速缓存未命中，计算机必须访问主存储器或硬盘才能提取信息，这样速度将会慢一些。

Storage and retrieval of information is immensely important.

储存和提取信息是极为重要的。

Methods of drawing out information have to be carefully monitored.

提取信息的方法必须小心慎用。

This arithmetic records the statistical characteristic of the part of picture writing secret information.

该算法记录下载体已经进行密写部分的统计特性，如果被嵌入的秘密比特与原始像素值的最低位相同，就不作改动否则就根据该统计特性进行增1或减1的调整在接收方，提取信息时只需要将载体图像的最低比特位提取、解密即可恢复秘密信息。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
