双语例句
- Finally, we draw a conclusion that the defects were chained cestode stomas.
最终,综合判定该缺陷为链状条虫形气孔。 - Whereas, the stomas of the upper epidermis of the thin-leave type settle strongly, there are no dividing between palisade tissue and spongy tissue in the diachyma, the vascular bundle sheath consists of lignification and suberin cells.
细叶型的叶上表皮气孔强烈下陷,叶肉无栅栏组织和海绵组织的区别,由木质化或栓质化细胞形成维管束鞘。 - The ornamental abilities that absorbing formaldehyde is direct ratio with the area of the leafs, and is import with the the number of the stomas.
植物吸收甲醛与叶面积成正比,与气孔数量有关系。 - The resistance of strawberry to aphids was positively related to the density of pubescences and the content of lignose, and negatively to the content density of stomas.
草莓品种对蚜虫抗性与叶片背面的茸毛密度成正相关,与气孔密度呈显著负相关;与叶片的木质素含量成正比; - The response of stomas of woody plants on areas of different polluted types
木本植物气孔对不同污染类型的反应 - The ordinary methods to observe the stomas as water slice, blotting, transparent tape, nail polish and so on.
常规观察叶片气孔的方法主要有水装片法、印迹法、透明胶带法和指甲油法等。 - The epidermis of leaves was also studied by optical microscope, the frame type of stomas and arrangement of epidermic cells was found helpful in taxonomy of the genus.
此外对叶表皮还采用光学显微镜进行了研究,发现叶表皮细胞形态、排列方式对分类学研究也有辅助作用。 - Results All the 11 anastomotic stomas healed by first intention with 2 incisions infected.
结果11例手术吻合口全部一期愈合,2例切口感染。 - Germ-tube always branched into several tubes and infected two stomas, or several tubes infected one stoma at the same time.
芽管常形成树杈状或根状分枝,一个芽管分别侵入两个气孔或几个芽管同时侵入一个气孔。 - In gas exchange. The stomas closes, and all of the gas exchange rate, photosynthetic rate and transpiration rate decrease. The ratio of photosynthesis and water utility is increased under drought stress, since transpiration was inhibited more strongly than photosynthesis.
在气体交换方面,气孔关闭,气体交换速率减缓,光合速率和蒸腾速率都下降,但是,与光合速率相比,由于蒸腾速率受到更强烈的抑制,水分利用率提高。
