This paper brings forward a non-destructive measurement method based on bilinear mapping which aimed at problems of how to correct image and wipe off texture feature to conduct non-destructive measurement of soybean-leaf area using computer vision technology.

该项研究针对大豆叶面积无损测量中校正图像和去除叶片纹理特征等问题上，提出了基于双线性映射的无损测量法。

During the latest fifteen years a great progress has been achieved on transgenic research of the main crops including soybean, maize, rice, and wheat. Almost all the transformation techniques have been successfully used in these main crops. Especially for the Agrobacterium mediated transformation, not only successes it in soybean, a recalcitrant dicot plant to transformation, but also in rice, maize and wheat of monocot plants.

近15年来，大豆、水稻、玉米、小麦等主要农作物转基因研究取得了较大进展，几乎各种遗传转化方法在这些作物上都取得了成功，尤其是农杆菌介导法，不仅在难转化的双子叶作物大豆上取得了成功，而且在单子叶作物水稻、玉米、小麦上先后取得了突破。

The results of phylogenetic analysis showed that DFR from Hyacinthus orientalis and from Iris x hollandica clustered together firstly ,and then came those from other monocotyledon, dicotyledon came subsequently.

聚类分析表明，最先与风信子聚类合并的是鸢尾，其次与其它单子叶植物聚类，最后与双子叶植物聚类。

Vector pDLBRBNPT contained plant selective marker gene nptⅡ and vector pCDMAR-Hyg contained plant selective marker hygramycin phosphotransferase gene , they fitted to dicotyledon and monocotyledon transformation respectively.

载体pDLBRBNPT含有植物选择标记基因nptⅡ，适合双子叶植物转化；而载体pCDMAR-Hyg的植物选择标记潮霉素磷酸转移酶(Hygramycinphosphotransferase，Hyg)分离，主要用于单子叶植物转化。

The methods disclosed herein can be used with a variety of host cells, including for example, dicotyledonous and monocotyledonous plant cells.

这里所公开的方法可以与各种宿主细胞，包括例如双子叶和单子叶植物细胞一起使用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
