1、絕干狀態：當木材中的自由水和結合水被清除后，木材的狀態就稱為絕干狀態；
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、纖維飽和狀態：纖維飽和點指的是一個臨界狀態，一般來說，自由水的多少對于木材的物理性質影響并不大，而結合水的含量卻對防腐木的各項物理力學性能影響很大。
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、生材狀態：剛砍伐下來的木材處于生材狀態，細胞腔和細胞壁中都含有水，自由水的量會隨季節發生變化，而結合水則處于飽和狀態。
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、氣干狀態：將生材放置于大氣環境中自然干燥，當生材中的水分達到平衡狀態時，此時的狀態就是氣干狀態。一般來說，南方地區氣干狀態的含水率較高，大約為15%~16%，而北方地區則在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%.
防腐木變形與開裂的原因：
Reasons for deformation and cracking of anti-corrosion wood:
木材做為一種天然的材料，開裂是因為含水率及木質年輪不同導致的，屬于正?，F象。防腐劑做為一種防腐材料，其目的在于防腐，確保木材置在惡劣環境中也可以抵擋白蟻侵蝕、孢子真菌的生長與腐朽、水生生物的寄宿以及其他昆蟲的繁殖，有效的延長木材的使用時間。
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.
