To find the point of failure of dark line will tend to make electricians helpless, so the design of handheld lighting circuits detector is necessary. This article discribes the main idea of probes inducing the alternating electric field around electricity cables[1]. The collected signal in system is processed through the amplification, filtering, comparison circuit and STC12C5A08AD. Finally, real-time display grid numbers and testing time on 12864. The system’s functions include position detection, discrimination, position records and others. The system can well distinguish different cable. After testing and certification, system is reliable, stable and with practical value.

ABSTRACTA new method for the build-up of non-centrosymmetric multilayer thin films has been developed for the first time using an electric field-assisted electrostatic self-assembled monolayer (EF-ESAM) technique. An increase by 116% of the second-harmonic intensity of the films has been observed in comparison with that of ESAM film.

Alternating Electric Field

A rapid method of estimating the moisture in a sample of wheat is described. This method depends on the effect produced in a specially arranged radio circuit in which an alternating current of high frequency is generated. When a container holding some of the wheat under examination is introduced into the rapidly alternating electric field, a change occurs in the strength of the current which may be measured by an ammeter in the circuit and which may be immediately interpreted as a measure of the moisture content of the wheat.

A new experimental method for determining the dependence of the electron mobility on the longitudinal-electric field has been developed. The development, validation and explanation of this new method has been carefully carried out. We have applied this procedure to standard submicron MOSFETs and after having obtained the mobility dependence on both the transverse- and longitudinal-electric fields we reproduced the experimental output curves. The saturation velocity has also been calculated using the mobility curves obtained by this new method.

As If

The surface of an air bubble is a particularly simple one at which to examine the electrical conditions which attend all small particles when immersed in a liquid. An air bubble may be considered as a type of coarse suspensoid, which, on being immersed in water, acquires a charge and moves in an electric field as if negatively electrified. The present work is a continuation of that already published ('Roy. Soc. Proc.,' A, vol. 106, p. 315 (1924)) and deals chiefly with the charge on the bubble immediately after it enters the liquid; this is examined experimentally and also theoretically. In addition, a new method of calculating the potential difference between the bubble surface and the interior of the liquid is suggested.
