The influence of different disperse conditions on the disperse state of xonotlite secondary particles was studied intensely.

There have been some researches on the dispersion of carbon nanotubes, but the disperse conditions are not quantitatively demarcated.

The application of black matrix graphite in color tube and the production technology and dispersion condition and research progress are summarized.

This paper is devoted to providing an iterative algorithm for computing the maximum likelihood estimators of discrete distributions under an increasing convex order constraint,and the convergence of the algorithm is proved.

Converting the continuous distributions into discrete distributions will decrease a large amount of computation in Monte-Carlo simulation.

Taking advantage of nonlinear time history analysis results of a single-degree-of-freedom system with the hysteretic model of bilinear,conditional distribution type of ductility demand factors are verified by goodness-of-fit tests.

Based on multiplication theorem of probability,an effective approximation is presented to the bi-normal distribution with substituting the original conditional distribution by the standard normal distribution of the same expectation and variance.

It has also been proved that the conditional distribution of order statistic in order of second component for given a order statistic of first component is the same as the distribution of order statistic of certain one dimension sample.
