TL;DR: In this paper, a direct-current combined field intensity and ion current density synchronization measurement system based on wireless communication is presented, which consists of at least 10 directcurrent combined fields intensity probes, 10 ion current densities, one upper computer and one PC terminal.

TL;DR: In this paper, a radio interference computing method for computing radio interference to an alternating-current high-voltage multi-loop electric transmission line was proposed, which includes dividing a super-highvoltage and an extra-high-volatile multilayer EHV line into a first line group and a second line group.

TL;DR: In this paper, a method for getting rid of radio jamming field measurement abnormal values is proposed, which comprises a step (1) of obtaining a histogram of radio data and a distribution pattern of the histogram; a step(2) of preliminarily determining whether the radio data belongs to normal distribution according to the distribution pattern, and step (3) of adopting a single sample K-S inspection method to determine whether radio data belong to the normal distribution; step (4) of using robust-Z inspection to get rid of abnormal data.

TL;DR: In this article, the utility model relates to a multichannel power frequency magnetic field intensity synchronous measurement system, the system includes: the next machine, its and upper computer connection for carryout communication and data transmission with the host computer, the host computers, it links to each other with the next machines for send to the next Machine according to sampling interval and read data command, and the measured data who sends the nextmachine gathers, demonstration, storage, assay and warning, a plurality of power frequency magnetometer measuring unit, it is used for measuring the powerfrequency magnetic field

TL;DR: In this paper, the authors proposed a sound reduction measurement method for a paralleling-reactor sound shield, where the sound reduction is calculated through measurement of the sound intensity levels, sound intensity which is a vector and has directionality.
