1、绝干状态：当木材中的自由水和结合水被清除后，木材的状态就称为绝干状态；
1. Absolute dry state: when the free water and combined water in the wood are removed, the state of the wood is called absolute dry state;
2、纤维饱和状态：纤维饱和点指的是一个临界状态，一般来说，自由水的多少对于木材的物理性质影响并不大，而结合水的含量却对防腐木的各项物理力学性能影响很大。
2. Fiber saturation state: fiber saturation point refers to a critical state. Generally speaking, the amount of free water has little effect on the physical properties of wood, while the content of combined water has a great impact on the physical and mechanical properties of anti-corrosion wood.
3、生材状态：刚砍伐下来的木材处于生材状态，细胞腔和细胞壁中都含有水，自由水的量会随季节发生变化，而结合水则处于饱和状态。
3. Green wood status: The newly cut wood is in green wood status. The cell cavity and cell wall contain water. The amount of free water will change with the season, while the combined water is in saturated state.
4、气干状态：将生材放置于大气环境中自然干燥，当生材中的水分达到平衡状态时，此时的状态就是气干状态。一般来说，南方地区气干状态的含水率较高，大约为15%~16%，而北方地区则在12%~13%左右。
4. Air-dried state: Put the green wood in the atmospheric environment and dry it naturally. When the moisture in the green wood reaches the equilibrium state, the state at this time is the air-dried state. Generally speaking, the water content in the dry state is high in the south, about 15%~16%, while in the north, it is about 12%~13%.
防腐木变形与开裂的原因：
Reasons for deformation and cracking of anti-corrosion wood:
木材做为一种天然的材料，开裂是因为含水率及木质年轮不同导致的，属于正常现象。防腐剂做为一种防腐材料，其目的在于防腐，确保木材置在恶劣环境中也可以抵挡白蚁侵蚀、孢子真菌的生长与腐朽、水生生物的寄宿以及其他昆虫的繁殖，有效的延长木材的使用时间。
As a natural material, wood cracking is caused by different moisture content and wood growth rings, which is a normal phenomenon. As a kind of antiseptic material, the purpose of antiseptic is to ensure that the wood can resist termite erosion, spore fungus growth and decay, aquatic organism lodging and other insect breeding when placed in a harsh environment, and effectively prolong the service life of the wood.
