用法例句

To improve the permeability of larch wood,high intensive microwave irradiation was applied to wood.

采用高强度微波辐射落叶松木材,将微波处理的木材试件与未处理试件在相同的条件下进行加压注水试验,测定吸水增重率(WAR),用于评价木材的渗透性。

The objective of research is to set up a new technology for the deresination of larch wood which is modified by the method of microwave-cell-explosion.

微波细胞爆破法改性落叶松木材的脱脂技术以探索建立落叶松木材脱脂新技术为目标,其基本原理是:高含水率(30-60%)的落叶松生材,在高强度微波场中,木材中水分子被极化并迅速旋转、相互摩擦、生热汽化,细胞内的蒸汽压力迅速增高,破坏木材细胞壁上的纹孔膜等细胞薄弱组织,形成新的流体通道,从而使落叶松木材的渗透性得到较大地改善。

Larch wood resource is abundant in China.

但是由于其渗透性差、内应力大，导致难于干燥、容易开裂和变形，此外还有树脂含量高的缺点，给其干燥、保护处理等加工带来了很大的困难，因此目前落叶松木材主要以原木的形式用于建筑、矿业等行业以及用于造纸，利用价值很低。
