The canopy structure and leaf morphological characters of 4 sugarcane genotypes at different leaf layers on seedling were studied by using CI-100 plant canopy instrument and CI-203 area meter instrument. The results showed the leaf morphological parameters, canopy structure and radiation transmission at different leaf layers were notably different among different genotypes. The variation of Ila, Amfi, Dl at different leaf layers were mainly caused by the leaf width at relevant position. The variation of K at different leaf layers was related to Amfi and Dl. The variation of Td（transm. coef. for diffuse penetration）had significant correlations with Ila, Amfi and Dl. The variation of Tr（transm. coef. for radiation penetration）had significant correlations with Dl, leaf width and the ratio of leaf length to width. The variation of Par had significant correlations with Ila, leaf area, leaf width and the ratio of leaf length to width.

摘要利用CI-100数字植物冠层分析仪和CI-203叶面积分析仪测定了4个甘蔗品种不同叶位层的冠层参数和相应叶位叶片的形态特征，结果表明：不同基因型不同叶位层间叶片形态、冠层空间结构和冠层辐射特征存在显著差异，不同叶位层叶面积指数、叶簇倾角和叶分布的变化主要由冠层内不同叶位叶片叶宽的变化引起，而不同叶位层消光系数的变化主要与叶簇倾角和叶分布有关；散射光透过系数的变化主要与叶面积指数、叶簇倾角和叶分布有关，直射光透过系数的变化主要与叶分布、叶宽、长宽比有关，光合有效辐射的变化与叶面积指数、叶面积、叶宽、长宽比有关。

The ceremonies of purification from legal contamination, ie for the people, various expiations, for the priests, the washing of hands and feet, the shaving of the head, etc. St. Augustine says the sacraments of the Old Law were abolished because they had been fulfilled (cf. Matthew 5:17), and others have been instituted which are more efficacious, more useful, easier to administer and to receive, fewer in number "virtute majora, utilitate meliora, actu faciliora, numero pauciora", Cont.

In digital signal transmission systems, parallel transmission is the most efficient transmission technique at present for non-ideal channel. In which, orthogonally multiplexed QAM system and discrete multitone system are two typical systems.

在数字信号传输系统中，并行传输是目前最有效的一种抗信道失真传输技术，而正交复用QAM和离散多载波是两种并行传输系统典型的实现方式。
