In view of different defect types,the methods and developments in domestic and foreign of the remaining strength assessment about defect pipelines were introduced,technical thoughts of remaining strength was introduced.

To the bad noise interference problem occurred in the signal of pipeline defect magnetic flux leakage inspection,the empirical mode decomposition(EMD) method developed recently was used to the noise suppressing and the effective signal extraction for the signals of magnetic flux leakage inspection.

In ultrasonic nondestructive testing of pipeline defect, the echo signal of pulse reflection, which is used as a basic testing data, is disturbed by electronic noise (including thermal noise and digitalization noise), and structure noise.

This article disussed the common moral defects of cosmetic medical organization,cosmetic patients and their relatives,society,news media and so on in the cosmetic dispute respectively,and the difficult ethical problems left by the disposals of current sociol system and law to cosmetic medical dispute.
