| 1. | Sapwood contains xylem vessels, but not as strong as heartwood . 边材含有木质导管,但不如中心木质那样坚硬。 |
| 2. | If timber poles are used, the bark can be peeled off the tops to expose the light colored sapwood . 如用圆木杆,可削去顶端树皮,露出木质部的明亮色泽。 |
| 3. | In older stems, only the most recent rings of xylem participate in the transport of materials. these make up the sapwood . 在老茎中,仅最新的木质部环参与物质的运输。这些木质部环组成边材。 |
| 4. | Reviews of research work on sap flow process in tree species sapwood 树木边材液流传输研究述评 |
| 5. | Effect of pretreatment with freezhing on carbonization of sugi cryptomeria japonica sapwood 冷冻处理对日本柳杉边材炭化的影响 |
| 6. | Test method for penetration of preservatives in wood and for differentiating between heartwood and sapwood 木材防腐剂渗透性和木材心材和边材之间分化的试验方法 |
| 7. | Standard test methods for penetration of preservatives in wood and for differentiating between heartwood and sapwood 木材中防腐剂渗入度及心材和边材间差异的标准试验方法 |
| 8. | The wood varies in colour from a flesh shade to a light reddish - brown with little distinction between heartwood and sapwood 木材颜色从肉色到淡红褐色不等,边材和心材区别很小。 |
| 9. | The results show that the water consumption of transpiration can be reckoned through standard specific conductivity of standard tree and the relative model between breast height diameter of tree and sapwood area 结果表明,通过标准木的标准比导率和树木胸径和边材面积的相关模型,可以比较准确地推算出林分的蒸腾耗水量。 |
