数字

That is according to official figures – unofficially, they may be double.

这是根据官方数字得来的结果——若以非官方数字衡量，也许还要翻倍。

A great deal of experimental results are presented, proving that the digital watermark generated by the algorithm is unperceivable and shows great robustness to the common image processing like low-pass filtering, median filtering, Wiener filtering, nosing, cropping, rotation and JPEG loss compression, etc.

大量的实验结果表明，用本算法产生的数字水印能保证数字图像的不可见性，并且对常见图像处理均具有很好的鲁棒性，主要表现在低通滤波、中值滤波、维纳滤波、图像加噪，图像裁剪、图像旋转和有损JPEG压缩处理。

Also, in the days following the switchover, the digital signals being broadcast are unlikely to be up to snuff.

同样，数字电视转换后的一段时期，播出的数字信号也未必理想。

Bondage, we must take into account the characteristics of the computer theory of the development of digital photogrammetry, which is digital photogrammetry for the development of the theory and practice put forward a new opportunity, for example: Vanishing Point Theory and Applications, broad and multi-point theory and application of baseline three-dimensional theory and application.

的束缚，必须从计算机的特点考虑数字摄影测量的理论发展，这正是数字摄影测量为其理论与实践的发展提出了崭新的契机，例如：灭点理论与应用、广义点理论与应用和多基线立体理论与应用。

A numeral 1 in the ith component of the vector denotes the inclusion of the ith element of that particular subset;a 0 denotes its exclusion.

向量中的第I个分量为数字1表示集合的第i个元素在某一特定的子集中，用数字0表示不在某一特定的子集中。

A numeral l in the i-th component of the vector denotes the inclusion of the i-th element of that particular subset; a 0 denotes its exclusion.

向量中的第 i 个分量为数字 1 表示集合 T 的第 i 个元素在某一特定子集中，用数字 0 表示不在某一特定子集中。

A CW carrier signal, generated by Agilent Signal Generator, is transmitted to the subject, which reflects the modulated waves to the receiver antenna. The Agilent Spectrum Analyzer, with an under-conversion module inside, demodulates the received signal to 70MHz IF signal, which is then sampled by a ADC module in Agilent Vector Signal Analyzer. Digital quadrature demodulation is used to convert IF signal to baseband. We could finally get the respiration and heartbeat signal by further analyzing the baseband signal.

该系统由信号发射器产生载波，通过天线发射到被测物体；频谱分析仪内置的下变频模块将由物体反射回来的信号下变频到70MHz中频；中频信号经矢量信号分析仪采样，然后经过数字正交解调变频到基带信号；对基带信号进行滤波、FFT等进一步的数字信号处理后即可获得探测的心跳和呼吸信号。

That is to say, by using the special digital converter or running relevant arithmetic, it converts the radio signal to intermediate frequency signal and completes the base-band signal process that isn"t the veriest SR and is named "software defined radio. This paper introduces the rapid system prototype into the design of software radio system, which has great advantage because rapid system prototype technology can be used to describe the future application.

由于受到硬件性能如A／D、D／A及DSP芯片处理速度的限制，目前的软件无线电系统多采用折中的实现方案，增加专用的数字变频器或者运行数字变频算法，将射频信号变频到中频，然后再进行基带信号处理，这样的软件无线电系统又被称之为"软件定义无线电"，它并不是真正意义上的软件无线电。

Through carries on the Hough transformation after the license plate outline, with one kind of new K average value algorithm fits the edge straight line, obtains the straight line angle of tilt then to carry on the adjustment to the image; Uses one kind of fast pattern plate match union vertical and the horizontal axis projection carries on the division to name board various characters, raised the character division speed and the precision; Finally separately carries on the recognition to the alphanumeric character and the Chinese character character, the alphanumeric character uses the BP neural network algorithm, but the Chinese character character uses based on the most close neighbor sorter template matching algorithm.

通过对牌照轮廓进行Hough变换后，用一种新的K均值算法拟合边缘直线，得到直线倾斜角度进而对图像进行校正；采用一种快速的模版匹配结合垂直与水平投影法对船名牌上的各字符进行分割，提高了字符分割的速度和精度；最后分别对数字字符和汉字字符进行识别，数字字符采用BP神经网络算法，而汉字字符采用基于最近邻分类器模板匹配算法。

Vice-principal B introduced the digital media technology and technical innovation in our university.

区副区长于大力在会上介绍了我国关于数字媒体技术研发情况以及我市与南岸区的相关情况，B副校长在会上介绍了我校关于数字媒体技术及科技创新工作的情况介绍，丘成桐教授一行就几何信息科研公司研发的三维动态实时核心技术、科研成果、媒体曝光、实例应用、三维智能设想及系列产品开发进行了说明与演示，并回答了与会领导和专家提出的疑惑。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
