该系统采用了一套采样速率可达20MHz 的高速数据采集系统，并采用抗干扰性强、传输速率高的CAN 总线进行上下位机通信，同时该系统的上位机软件可实现在线监测数据的软件滤波处理、数据库的信息查询、数据的分析显示和监测信息的网络发布功能。

Some key technologies including high reflectivity and high temperature resistant detection needle, high precision driving unit, sampling spot and driving unit positioning, has been turned out effectively.

较好地解决了具有高反射、耐高温系列探针的研制，高精度传动装置的研制、采样点与传动装置精确定位的控制等关键的技术。

Moreover, during the radar signal generation, static and dynamic characters of backscattering coefficient are set up, and time sampling of each clutter unit is computed with voltage character and power spectrum character, and the sampling signals are added in every distance gate to output time series. In addition, noise is modeled with a function of Gaussian stochastic process.

在雷达信号模拟中，建立了杂波后向散射系数的静态和动态特性，从杂波的幅度统计特性与功率谱特性入手，计算了每个杂波单元的时域采样，按照对应的距离门叠加各个距离模糊间隔上的回波信号并形成时间序列，并采用一个高斯随机过程的样本函数来表示噪声模型。

Control circuit mainly include the exchange of sampling unit, the external expansion unit, display units, the control unit and other components, compact hardware, Programming easy, simple control.

控制电路主要由交流采样单元、外部扩展单元、显示单元、控制单元等组成，硬件紧凑，编程容易，控制简单。

You may not be aware of this sampling phenomenon, but we all do it to some degree.

你可能不知道这些采样现象，但我们不同程度都有这样的做法。

So, all you know is what the frequency of the signal is relative to the sampling rate.

那么，现在你能知道的所有情况是，信号的频率与采样率的比值

You know that the sampling rate is constant, you just don't know its frequency.

你知道采样率是恒定的，你只是不知道频率。

This paper concludes that the new method for selecting the sampling period is desirable.

本文的结论是，这种选择采样周期的新方法是可取的。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
