Aiming at the special demand of aviation domain to fault missed detection risk, the undesirable false alarms and undesirable lemissed detections risk problem of the chi-square test was searched, and material example and simulation analyzing indicate that snapshot algorithm is incapable of satisfying the aviation requirements for detection risks.

Study on the leaking risk of rocket kerosene stored on launching site based on fuzzy theory

There are multiple sources of risk in segmental tunnelling, so analysis is made of the source of leakage risk from the tunnel tail sealing.

This paper lays the emphasis on the anlaysis of maleriality and detection risks influence on substantive tests,through the scientifically designing time,nature and scope of it,so as to lower the entire auditing risk into acceptable level.

Discussed the normal regulations inspection and the risk inspection at inspection the procedure,inspection strategy,the equipments rating and inspection the period different and similar of etc.
