Can be used as monitor,LF vented radiation,it have crossover network and

监听箱使用，低频倒相辐射，内置优化设计分频网络和高音保护器。

Its balanced armature drivers and three-way crossover network deliver powerful lows, lush midrange, and crystal-clear highs that add incredible realism and punch to your listening experiences.

它所具有的平衡电枢单元和三路导管网络，将为您带来强劲的低频、lush的中频和水晶般通透的高频，以及难以置信的真实感觉，冲击你的听音经历。

Since the glint noise is a low-frequency noise and its bandwidth is usually lower than that of flight control system, therefore low pass noise filtering is not practical for guidance command and noise are not distinguishable.

闪烁杂讯属低频杂讯，通常比飞控制系统频宽还要低，无法与导引命区分，所以能只用低通波器将其除。

Some of the examples in her book include the Tang Shan earthquake in China, which occurred on 28 July 1976, and left 650,000 people dead. The catastrophic event was preceded by an airglow, said to have been caused by Soviet ELF wave experiments to heat the ionosphere.

在其书中举出了一些例子，其中包括1976年7月28号发生的中国唐山大地震，剥夺了六十五万人的生命，但在这灾难发生之前有大气辉光现象，据说是苏联极低频电磁波试验加热电离层导致了这一惨烈的灾难发生。

Based on the low frequency approximation of TIWL response in a homogeneous, transversely isotropic conductive medium, Zhdanov et al. derived the analytic formula to extract the conductivity of the anisotropic formation, the borehole dip angle and tool azimuth from the response of TIWL. These can be used as the foundation of TIWL data interpretation.

利用在横向各向同性均匀介质中测井响应的低频渐近式给出了由张量感应测井响应提取地层各向异性电导率和井孔倾角与方位角信息的解析公式，为张量感应测井资料解释奠定了基础。

Partial discharge measurement at 0.1Hz VLF voltage is inefficient because the magnitude and polarity of VLF voltage change slowly.

研究还表明，由于超低频电压的幅值和极性变化缓慢，不利于准确检测介质缺陷的局部放电。

The thesis studies several key issues on sampling computation and digital waveform synthesis in electrical measurements thoroughly, and applies some of the results into the precision measurement of VLF voltage.

本文对精密电测中的采样计算及数字波形合成的几个关键问题进行了深入细致的理论研究，并将有关的结果应用于超低频电压的精密测量中。

A 0.1Hz VLF high voltage system is developed through the coorperation of Harbin University of Science and Technology and Harbin Power Administration.

介绍了哈尔滨理工大学和哈尔滨电业局合作研制的0.1Hz超低频高压试验系统。

Out in the no-mans land of the international waters are the only means of communication with the submarines, to use radio in the VLF or ELF range.

在茫茫大洋深处，唯一可用的通信手段就是甚低频或者极低频无线电。

Against the models established, the equivalence of DC voltage, OWV and VLF voltage to AC voltage has been widely investigated. It is found that the equivalence factor of OWV is between 1.2 and 1.8, that means OWV has a good equivalence to AC voltage.

针对建立的试验模型，讨论了直流电压、振荡波电压、超低频(0.1Hz)电压与交流电压的等效性，发现振荡波电压的等效系数在1.2-1.8之间，与交流电压等效性较好。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
