What we need to do for measurement, data analysis, handling and recording is to input the corresponding operations to the computer.[7] Utilization of longitudinal and lateral comparison approach When judging whether the transformer windings have the distortion defect, we exploited multiple testing methods for general comparison, combined low-voltage impedance test and frequency response analysis together, and conducted a mutual test with routine test methods such as dielectric loss test and oil chemistry test[8]; on the other hand ,we utilized longitudinal and lateral comparison approach, i.e., laterally compare the three-phase short circuit impedance curves of the same transformer[9], or longitudinally compare the curves tested in the factory, first time test in the spot and the current.
The device we developed has a compact structure and is easy to carry.

Considering porous ceramic support requirements for pore structure and bending strength, the suitable firing temperature is between those higher than melting temperature of the binder and lower than Taimen temperature of cordierite aggregate, namely 1220-1260°C.

At present, SLT has found its wonderful application in many fields such as speech recognition, character recognition, medical designing, combinatorial chemistry and time series prediction.
The basic step to realize the SRM principle in SLT: First, design certain structure of function set which makes each subset can obtain the minimal empirical risk ( )emp lR D ; Then only need to choose the proper subset which has the confidence interval l h φ       minimal, and the one in this subset who can minimize the empirical risk is just the optimal function.
