61 The test method of the eddy current sensor in the multi - frequency and multi - parameter is studied.

62 Such differences result in uneven eddy current density on electrode surface, which will affect the electrode remelting rate.

63 Eddy current impedance diagram analysis method has high ability in classifying flaw Signals. Sig-nals are charactered by autocorrelation matrix eigenvalue and eigenvector of the signals measured.

64 The images of DTI are easily distorted by the effect of eddy current and the difference of magnetic susceptivity.

65 The factors affecting the true penetrating depth (TPD) of eddy current probe were studied by directly measuring the distribution of the magnetic field inside a solid conductor.

66 All of high-speed vehicles have associated braking system, mainly applies air brake, cooperated with power brake, eddy current brake, electric magnet wheel brake, etc.

67 When contacts the wall surface or the encumbrance, the eddy current air current then diffusion circulation to the entire indoor space, forms the air cycle effect again and again.

68 Through experiment the best eddy current exciting frequency for the detection of the high voltage transmission line is determined.

69 And the auxiliary brake uses an Eddy current brake or EATON brake.

70 Calculations and experiments are carried out on both magnetic flux density and eddy current loss of the non-magnetic steel plate and of the coil in this model.

71 The rule of magnetic induction density(sentencedict.com), induced eddy current and electromagnetic force varied with high frequency sine exciting current was investigated.

72 Practical inspection showed that eddy current testing was fast, sensitive and accurate.

73 The far field eddy current testing system for trial was developed.

74 Lift - off effect is a common unnecessary factor in eddy current test.

75 A data measurement system of the eddy current sensor based on the CAN is presented. A parallel interface technology, which enlarges CAN, in EPP mode is mainly discussed.

76 The basic theory of edge element method and its application in 3-D nonlinear eddy current field are researched in this paper.

77 In order to realize getting useful signals[Sentencedict.com], the orthogonal vector LIA (Lock-in Amplifier) was applied in dual-frequency eddy current NDT (non destructive testing).

78 For improving the detection sensitivity, it is important to choose the appropriate parameters for the pulsed eddy current PEC system.

79 An advanced technique , pulsed eddy current detection, was introduced for corrosion detection.

80 Based on an eddy current array instrument and a sensor, the formation procedures of eddy current array C scan image are simply introduced.

81 Engine brake, exhaust brake and electrical eddy current rail brake have been used independently as continuous brake device for long times.

82 Major and minor loop areas are computed from simulated B / H characteristics and thereby the hysteresis and eddy current components of the measured no-load loss are calcu1ated.
