为了阐明热带森林中树种的生长胁迫机制，采用应变片技术研究了印度尼西亚西爪哇种植的39年生柚木（Tectona grandis）树的外周和内部纵向释放应变。结果表明，树木生长速度对周边和内部纵向应变的释放没有影响。然而，释放的应变分布在树干内部，从髓到外围，生长速度的影响显着，缓慢生长的树木产生陡峭的释放应变梯度。
Summary In order to clarify the growth stress mechanism of tree species in tropical forest, peripheral and internal longitudinal released strains in 39 year-old teak (Tectona grandis) trees planted in West Java, Indonesia were investigated using the strain-gauge technique. Results showed that both of the peripheral and internal longitudinal released strains were not affected by the rate of growth of the trees. However, released strains distribution inside tree stem, from pith to periphery, were significantly affected by growth rate; slow growing trees generate steeper released strain gradients.
