It can diagnose the tractors flameout failure while the noise signal had been analyzed with wavelet.

基于MATLAB6.5，采用Daubechies小波对近场法测得的发动机缸盖上方的噪声信号进行分解，提取了包含燃爆噪声信号的高频细节分量，该方法可诊断拖拉机失火故障。

This kind of choice imbeds the method of the watermark data position, making use of the picture well the characteristics of the high information of frequency and the sense of vision characteristic of the person, be advantageous to watermark"s can"t see the sex and flimsiness.

这种选择嵌入水印数据位置的方法，充分利用了图像中高频信息本身的特点和人的视觉特性，有利于水印的不可见性和脆弱性。

It is used for cleaning the material in flourmill, rice plantfeed works, food plant, oil plant, chemical plant and so on.

ABSTRACT Yb-doped calcium fluorapatite single crystals were successfully grown by the Czochralski method.

摘 要 用高频感应提拉法生长了掺Yb3+氟磷酸钙晶体，获得了理想的生长工艺参数。

Owing to its small volume, light weight, high efficiency, succinct circuitry, high reliability and great capability of self-equalizing output loads in different circuitries, the Fly-back Converter becomes the optimally topological form of designing auxiliary power supply of high frequency switching power and driving power supply of power switching.

由于反激式变换器不但具有体积小、重量轻、效率高、线路简洁、可靠性高等优点，而且还具有较强的自动均衡各路输出负载的能力，目前反激式变换器的电路拓扑形式已成为人们设计高频开关电源的辅助电源以及设计各种功率开关驱动电源的首选。

With the high frequency and strong destruction of enterprise crisis, managers pay more and more attention to the forecasting technology to forewarn and control crisis as early as possible.

企业危机的高频发生和破坏性使得战略决策者日益关注运用预测技术对危机进行早期预警以及时控制，建立危机预警系统已成为企业危机管理中的重要组成部分。

The experimental result indicates this method be able to express shock-wave signal more exactly and embody in the experiment the particularity and fortuitousness.

这种方式较好地表现了信号的整体性质，而从信号分析的角度看，却没有涉及实际信号中所包含的高频成分的特点和规律，即信号的细节特征被完全忽略了。

HIGH FREQUENCY, The frequency band between 3 and 30 MHz.

高频， 频率带在3至30兆赫之间。

The first, look like each detail picture of direction of picture and each layers to carry on DCT towards get of again, then will imbed to look like the son diagram DCT transformation through two value watermark pictures of the false random row preface behind of the part of the high part of frequency and the detail son diagram energy concentration.

本论文中提出的第一种算法是一种基于离散余弦变换和离散小波变换相结合的脆弱水印方法，即：先对图像进行离散小波变换，再对得到的近似图像和各层各方向的细节图像进行离散余弦变换，然后将经过伪随机排序的二值水印图像嵌入到近似子图DCT变换后的高频部分和细节子图能量集中的部分。

High frequency modulation and phasic demodulation technologies are also used to improve the resolution in dynamic measurement.

采用对光强进行高频调制和相位解调的方式提高了系统的动态测量精度和稳定性。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
