n.密閉；緊密；不滲透性

The ability to move air through plant canopies is related directly to the tightness of the green house. 空氣通過植物冠層移動(dòng)的能力直接與溫室的密閉程度有關(guān)。

Stop at the point where it starts to lose tightness and definition. 在它開始失去緊密和定義的點(diǎn)時(shí)停止。

Experimental and simulative results are given to verify the facts that the resolution and the pattern fidelity are sensitive to the contact tightness between layers. 實(shí)驗(yàn)與理論研究結(jié)果均表明采用銀膜超級(jí)透鏡的光刻技術(shù)的分辨率和成形保真度與層間的緊密連接度密切相關(guān)。

n.不透氣；氣密；密封
