The relative curves between natural frequencies and spring coefficients were given, and the characters of modes were described.

Study on circular corrugation on turned face and its causing reasons;

According to food fluidization for freezing process existing problems,a new type of food quick freezer with wave-vibration and semi-fluidization was development,it is based the working characteristic of fluidized-quick-freezer, with the lower wind speed and the higher vibrant intensity,which realizes individually quick frozen.

Based on the instances of turning or grinding spindly shaft and the theory on tiny vibration ofelastomer, this paper educes the natural mode of vibration in the process of typically machining, analyzes its eff-ect on the formation of surface corrugation, puts forward the measure against surface corrugation.

An analysis is made of an ideal vibration form in regard of a vibrating conveyer, and of its feasibility in practical engineering realization in this paper which also brings forth the method for designing the vibration system in purpose practice.

A lossless real-time compression algorithm for vibration waveform in steam turbine units;

Aiming at the vibration brought tail-wagging of principal axis and the real-time display characteristics of vibration waveform and locus of journal center in vibration monitoring system for generating units,drawing dynamic curve by feechart was introduced under the circumstance of C++Builder 6.
