Size curves of cocoon filaments can be regarded as non-stationary time series with finite length varying at random.
size of cocoon filament
The length of the size curves of cocoon filaments within one lot varies at random.
The purpose of the study is to found new mathematical model of size curves of cocoon filaments and to solve the problems about the methods, theories and demonstration in founding mathematical model.
Finally, pattern characteristic expression of size curves of cocoon filaments is put forward.
Discuss the problem that the discrete cocoon filament size produced by stair autoregressive model sesolve into continuous changeable cocoon filament size curve.
Abstract: Discuss the problem that the discrete cocoon filament size produced by stair autoregressive model sesolve into continuous changeable cocoon filament size curve.
Abstract: In accordance with the hypotheses that the length of cocoon filament is normally distributed random variable and the ratio of dropping end has optionally distributed form on cocoon filament, we derived the distribution of non-broken filament length of cocoon.
In order to simulate the size curves of cocoon filaments with finite length using AR( auto-regression) model, two methods of transforming the series lengths of the size curves of cocoon filaments are discussed, transforming experiments are carried out, transform error is analyzed.
Special methods and theories should be studied, in order to forecast size curves of cocoon filaments on the basis of investigated data of the size curves.
