电磁干扰

A meaningful scheme is provided for the simulation of the electromagnetic environment ofradars and the designing of practical jammers.

对模拟雷达工作的电磁环境及设计实用干扰机提供了一种有意义的方案。

It is found that comparing with compact single circuit transmission mode, T-type compact transmission mode of two circuits on the same tower and conventional transmission mode of two circuits on the same tower, the transmission mode of two circuits with same phase sequence in the same tower window need narrower corridror width, and the radio interference and audible noise caused by this transmisison mode is relatively lower, especially, the corona loss is reduced evidently, thus better economic and social effects can be obtianed by applying this transmission mode in a short distance under a centain condition.

从走廊宽度、电磁环境、潜供电流和防雷特性4个方面对750 kV同塔同窗同相序紧凑型输电方式进行了分析，发现与单回紧凑型、同塔双回T型紧凑型及同塔双回常规型输电方式相比，采用同塔同窗同相序紧凑型输电方式所需的走廊较小，无线电干扰和可听噪声相对较低，尤其是电晕损失明显减小，采用这种方式在一定条件下可获得较好的经济效益与社会效益。

Electromagnetic pulse generated by electrostatic discharge spark can severely interfere in normal operation of the electronic systems and even damage them.

静电放电火花产生的电磁脉冲会对电子系统的正常工作造成严重的干扰，甚至造成系统的损伤。

According to the traditional concept, the shielded signal wire should be applied in low voltage circuit to lower the interference and its screen connected to earth at both ends to weaken the electromagnetic coupling effect.

在传统的概念中，为降低弱电回路的干扰，宜采用带屏蔽层的信号线，且屏蔽层应两端接地，以削弱电磁耦合的影响。

The time series in Magnetotelluricscontains multiple spectra and often has unneeded natural electromagnetic signals and the interference of 50 Hz and its harmonic frequency.

大地电磁测深法野外观测得到的原始资料是包含多种频谱的时间序列，这种时间序列中常包含不需要的信息和50 Hz及其谐波的干扰。

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。
