Pulsed Doppler echocardiograph was used to test separately blood flow velocity wave of ascending aorta arcus, aorta and abdominal aorta in of 17 patients with aortic insufficiency with nonliner factor and results compared with those of 15 normal subjects of the same ages. The purpose was to disclose the regulation of blood flow waveform distortion in arterial system and the existance of shock wave.

应用超声多普勒对存在非线性因素的17名主动脉瓣关闭不全患者的升主动脉、主动脉弓以及腹主动脉进行分段逐点测试血流速度波，并和年龄相匹配的15名健康受试者为对照进行前瞻性探究，以探索人体动脉系统中血流波形畸变的规律及激波的存在。

A number of GPIB data acquisition products appeared throughout the 1970s and early 1980s, including voltmeters, digitizers, multiplexers, switches, digital I/O, D/A converters, and simple arbitrary waveform generators.

一定数量的GPIB 数据采集产品出现在70 年代和80 年代初期过程中，包括电压表，数字化器，多重通道，开关，数字式I/O， D/A 交换器，并且简单的任意信号波形发电器。

Use cvi prepared by the DSO virtual instrument interface, and through multi-machine Serial Communication waveform display.

利用cvi编写的DSO虚拟仪器界面，并通过串口多机通信实现波形显示。

A real-time DSO that could capture a single cycle of the same 12 GHz waveform would be prohibitively expensive.

可以在一个周期里捕获12GHz 波形的实时示波器会非常昂贵。

In practical communication systems, it is necessary to apply data equalizers to recover the original waveform from the distorted one.

在实际的通讯系统中需要以资料等化器来回复一个失真信号的原始波形，近来许多以类神经网路为基础的等化器设计被应用在严重失真的信号回复。

Moreover, second-winding current waveform of a current transformer is calculated under the transient current of the typical short-circuit fault by numerical method. The analysis shows that the relevant protection equipment may refuse to trip when the fault current is extra high. It will result in the maloperation of protective relays for loss of their selectivity, and cause other protective relays to operate beyond range, and extend the scope of shutdown of power supply.

在这些回路出口处发生相间直接短路等严重故障时，流过相应TA一次侧的故障电流可能达到TA额定工作电流的100倍以上，大大超过了保护用TA的10%误差容许倍数，将使TA严重饱和，从而影响相关的保护设备的动作性能，因此有必要对在这种特大电流作用下的TA的传变特性做一些探讨，以分析其对继电保护装置动作特性的影响及应采取的措施。

A very large value, often 1,000 micro farads or many times more, is needed to "smooth" the rectified waveform to "flat" DC.

这种电容通常是容量很大的，比如1000微法甚至再大很多倍。通过它才能得到平滑的直流电压。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
