1. The compression of the wood is easily achieved. 木材压缩容易实现。
2. Now, I'd like to touch briefly on extension and compression. 现在，我来简单地提及一下拉张与挤压。
3. Shannon showed how to calculate this limit, opening the way to the design of compression methods that cram maximum information into the minimum space. 香农展示了如何计算这个限度，这为设计压缩方法将最多的信息填入最小的空间开辟了道路。
4. It works in compression to divert the weight above it out to the sides, where the weight is borne by the vertical elements on either side of the arch. 在受到压力时，拱形结构能够起到将其上面的压力转移到侧面，在侧面的重量则由拱形结构两侧的垂直部分来承受。
5. No air bubbles were present in the green ice, suggesting that the ice was not formed from the compression of snow but instead from the freezing of seawater. 绿色冰层中不含气泡，这表明了这种冰层是由冻结的海水形成的，而不是凝结压紧的积雪。
