A sufficient condition for the stability of the two-station and three-processing-step re-entrant line with infinite supply is established in Weiss [13] by the Foster criterion.

A fast and accurate arithmetic method by using the judgement standard of minimum area method to evaluate the roundness error is introduced.

Boundary constraint criterion for onset of mechanical ice-cover breakup

An new criterion for convergence or divergence of alternating series

At present, there is not any criterion for distinguishing polarized magnetic system.

Implementation of discrimination criterion on active control force for cables vibration

In order to ensure the dependability of the settlement monitoring of the high graded road,it introduces the discrimination criterion of the abnormal data in the settlement of the high graded road systematically,analyzes the origins generating abnormal monitoring data in the settlement of the high graded road in detail,and brings forward the corresponding treating method.

Application of some statistical criteria in safety monitoring data processing

In this paper,the boundedness of the second-order non-linear differential equations with variable delay is studied by Lyapunov function,and some new criteria of the boundedness of the differential equations are given.

Extension of a discriminant criterion of non-autonomous system for dynamical instability;

The key point in phase correction is to get the phase correction angle based on a cer- tain discriminant criterion.
