This article indexed some idiographic methods on the service innovations of the information circulation on the book lending from the very beginning of the annotation of historical transformation as well as the brief analysis on circulation service mode of the book lending.

The information operational system is composed of information supply,information demand and information circulation and transmission.

Integrated with practice,the thesis analyses the question that libraries and intelligence and data institutions should attach importance to on the application of carriers,time in information circulation,lack of fidelity in information circulation and reversed supply in information circulation.

The current signals with splash or without splash are processed using cepstrum transform in spot welding,and then the plots of the cepstrum are compared.

Based different dealing ways of voltage and current signals in Siemens analog input modular EM231,two normal signal-proceeding programs are given after the analysis of modular inner proceed procedure in this paper.

This paper introduces that current signals of power system are acquired by Rogowski coil through optical fiber transmission system to low voltage side,which overcome the strong electromagnetic interference between the high-voltage signals,finaly transmission signals are send into the MSP430 to achieve signal measurement and display to improve the accuracy of measurement.
