The Depedence of Stockwood Density an Natural Drying Period for European Ash and Common Oak pdf HR EN | 157 | |
Summary: In this article the modifies of stockwood density are presented for European ash and common oak of various lengths (1, 2 i 4 m) and depending on period of natural drying. The original weighing in winter, spring and summer time, 174 days in natural drying has a significant influence on the stockwood density. The investigation results are presented with mathematical functions (parabola), tables and graphs. The equalization functions depending on density and natural drying period of stockwood for European ash are as follows: Ge.a. 1m = 877,560 – 1,397 t + 0,003 t2 …….. European ash, 1 m, Ge.a. 2m = 883,355 – 1,228 t + 0,002 t2 …….. European ash, 2 m, Ge.a. 4m = 876,444 – 1,062 t + 0,001 t2 …….. European ash, 4 m, Ge.a. forked branch = 1029,966 – 1,842 t + 0,005 t2 …….. european ash, “forked branch”, Ge.a. tree-stump = 1029,966 – 3,002 t + 0,010 t2 …………european ash, “tree-stump”, and for common oak are as follows: Gc.o. 1m = 1005,987 – 2,607 t + 0,005 t2 …….. common oak, 1 m, Gc..o. 2m = 1010,950 – 2,134 t + 0,002 t2 …….. common oak, 2 m, Gc. o. 4m = 1006,376 – 1,710 t + 0,0001 t2 …… common oak, 4 m, The parameters estimate of studied variables (density, drying period), variance analysis, F – test, t – test are presented in Table 4. Key words: density trend decrease; density; drying period; equalization functions.; natural stockwood drying; sortiment length | ||
