摘要:
Some of the responses to the comment by C. Lu on the tensile strength distribution of multiwalled carbon nanotubes are discussed. Lu made a number of claims that includes no size effect in chemical vapor deposition multiwalled carbon nanotubes (CVD MFNT) and a two parameter Weibull-distribution should be put on an equal footing with the lognormal or the normal distribution. The classic Weibull probability distribution function (pdf) is not to be put on equal footing with other pdf. It is the appropriate physical model for so-called extreme value phenomena which include fracture problems of various kinds. The Weibull model has a deeper link to physics than any other statistical model. The Akaike information criterion proposed by Lu seems to be an exercise in probability function fitting.
