Under the condition of eating completely freely,the piglets appetite, number of times for eating,eating intervals and interest in different types of fodder are observed and recorded.

The relationship between the sampling interval and the performance of control charts was analyzed using the average run time as a comparison standard.

Based on the opposite error separation measuring method,several main parameters conceming the measuring accuracey,such as sampling interval,reference ball parameter and installation eccentric,probe installation position and radius,and probe trigger force,have been analyzed qualtitatively for measuring the radial rotating error of precision shaftings.

Results The incidence of the plateau decreased with prolonging the sampling interval.

Furthermore,another model for sampling intervals decision b.

Aim\ To research the effect of projection numbers and sampling intervals on CT reconstruction capability in order to offer a basis to the system parameter for selecting.

This paper presents the first order attenuated growth model with non-uniform sampling intervals by Bayesian method, and gives out its updating recurrence algorithm of prior distributions, forecasting distributions and posteriori distributions with regard to the observational error variance known.
