文摘内容 Computer simulation was carried out on fiber length and width for plantation-grown Chinese white poplar (Populus tomentosa Cart. clone) and plantation-grown poplar 1-72 (P. x eurumericana (Dode) Guiner cv.). Skewness and kurtosis of measured results exhibited that distributions of the fiber length and width departured from normal distribution. Three-parameter Weibull density function was used in this investigation and the corresponding program was written with Turbo C. The results showed that profiles of simulated length and width histograms were similar to ones of measured histograms, and that there was a pretty good agreement between simulated and measured means of fiber length and width. There was a little influence on the simulated means from seed used in random number generator and number of simulated variables. That indicated that the simulation was steady when the seed and the number were altered. Different histograms can be obtained with different values of the location, the shape, and the scale parameter corresponding to different values of the minimum, the mean, and the standard deviation for fiber length and width. The simulation presented here can be used as a tool for the studies on the variations in fiber morphology。
