杨柳科：双子叶植物。杨柳科植物形态多样，有乔木，灌木及蔓生种类。包括柳树（柳属）和杨树（杨属）等。 |
| 5. | The minor veins join with other minor veins , forming a conspicuous network . the reticulate pattern of minor veins is characteristic of most dicotyledonous plants
细脉和其它的细脉联合形成一个连续的网络。细脉的网状式样是双子叶植物的主要特征。 |
| 6. | Since the plasmid is capable of independent replication in host cells of many dicotyledonous plants , it has been used as a cloning vector in gnetic engineering
在许多双子叶植物中质粒在寄主细胞中是独立的复制单元，所以可以在基因工程中用作克隆载体。 |

| 10. | The correctness is over 99 % . ( 5 ) shape features studied were aspect , first invariant central moment , elongatedness , roundness , circularity and thickness . aspect and first invariant central moment are the most effective shape features for identifying monocotyledonous weed from dicotyledonous weed , and the correctness was 93 %
( 4 )利用修正的色度公式，由判别分析法确定色度阈值，对杂草图像进行阈值分割，能够有效地识别植物与非植物背景，正确识别率在99以上，但色度的计算量大于过绿特征的计算量，不利于杂草识别速度的提高。 |
