So the computed result can not reflect the influence of the different rock mass to the movement characteristics and is quite different from the actual movement of falling rock.

实现签名认证的方法大体上可以分为两类，第一类是从签名样本中提取一些全局参数作为特征，第二类则把签名样本的整个信号序列，如坐标序列ux，uy、压力序列up、速度序列uv等看作是时间的函数，把这些函数作为签名的特征[4~6]。

The third chapter deduces the universal rules in the process of derivation. The substitution rule shows the nature of representations in two levels, the structure and the semantic levels with the features of combinatory and paradigmatic relations. The major parameter variations are interpreted with a weight on dislocation of word and the multi-functions of Wh-word in the frame work of the syntactical asymmetry. The fourth chapter further discusses the innate reasons of the English Wh-move and Korean Wh-in-situ in the syntactical system after summarizing the main findings of the comparison.

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。
