The main contributions of the second part of this dissertation are focused on the cryptographic properties of logical functions over finite field, with the help of the properties of trace functions, and that of p-polynomials, as well as the permutation theory over finite field: The new definition of Chrestenson linear spectrum is given and the relation between the new Chrestenson linear spectrum and the Chrestenson cyclic spectrum is presented, followed by the inverse formula of logical function over finite field; The distribution for linear structures of the logical functions over finite field is discussed and the complete construction of logical functions taking on all vectors as linear structures is suggested, which leads to the conception of the extended affine functions over finite field, whose cryptographic properties is similar to that of the affine functions over field GF (2) and prime field F〓; The relationship between the degeneration of logical functions and the linear structures, the degeneration of logical functions and the support of Chrestenson spectrum, as well as the relation between the nonlinearity and the linear structures are discussed; Using the relation of the logical functions over finite field and the vector logical functions over its prime field, we reveal the relationship between the perfect nonlinear functions over finite field and the vector generalized Bent functions over its prime field; The existence or not of the perfect nonlinear functions with any variables over any finite fields is offered, and some methods are proposed to construct the perfect nonlinear functions by using the balanced p-polynomials over finite field.

重新定义了有限域上逻辑函数的Chrestenson线性谱，考察了新定义的Chrestenson线性谱和原来的Chrestenson循环谱的关系，并利用一组对偶基给出了有限域上逻辑函数的反演公式；给出了有限域上随机变量联合分布的分解式，并利用随机变量联合分布的分解式对有限域上逻辑函数的密码性质进行了研究；给出了有限域上逻辑函数与相应素域上向量逻辑函数的关系，探讨了它们之间密码性质的联系，如平衡性，相关免疫性，扩散性，线性结构以及非线性度等；讨论了有限域上逻辑函数各类线性结构之间的关系，并给出了任意点都是线性结构的逻辑函数的全部构造，由此引出了有限域上的"泛仿射函数"的概念；考察了有限域上逻辑函数的退化性与线性结构的关系、退化性与Chrestenson谱支集的关系；给出了有限域逻辑函数非线性度的定义，利用有限域上逻辑函数的非线性度与相应素域上向量逻辑函数非线性度的关系，考察了有限域上逻辑函数的非线性度与线性结构的关系；利用有限域上逻辑函数与相应素域上向量逻辑函数的关系，揭示了有限域上的广义Bent函数与相应素域上的广义Bent函数的关系，以及有限域上的完全非线性函数与相应素域上向量广义Bent函数之间的关系；给出了任意有限域上任意n元完全非线性函数存在性与否的完整证明，并利用有限域上平衡的p-多项式的性质给出了有限域上完全非线性函数的一些基本构造方法。

The faintest color of the bud color is yellow green. In addition, the variation-coefficient of some morphological traits is very low such as the cotyledon length, the cotyledon width, the cotyledon color, the silique length and so on. The Cluster analysis was based on the morphological data. When the genetic distance was 7.61, 21 accessions were clustered into 4 groups. The accessions of the group 1 had white petal, mezzo flower stalk and the earlier pick period, which is divided into two subgroup when the genetic distance was 5. 98. And the model was Ba39 and Ba35. The accessions in the group 2 had the very slender flower stalk and the middle pick period, that model was Ba27. The accessions of the group 3 had yellow petal, the thin flower stalk and the later pick period, that model was Ba43. The main characters of the group 4 were that it had the latest pick period and many leaves.

基于形态性状的聚类分析，在遗传距离7.61处，把21份芥蓝种质划分为4类，其中类群G1包括14份材料，其植株的生长势中等，株型较为一致，花瓣颜色均为白色，花薹粗细较为适中，平口时期较早，在遗传距离5.98处自然形成2个亚类，分别以Ba39和Ba35为代表；类群G2包括2份材料，即Ba27、Ba33，其植株的生长势较弱，花薹很细，平口时期相对居中，代表材料为Ba27；类群G3包括4份材料，即Ba05、Ba09、Ba38、Ba43，其植株的生长势较弱，子叶颜色、叶柄颜色、花茎颜色、花蕾颜色均为黄绿色，花瓣颜色为黄色，花薹较细，平口时期较晚，代表材料为Ba43；类群G4包括1份材料，即Ba41，其植株的生长势较强，平口时期很晚，并且叶片数很多。

Although the researches of homemade tamping pick have already obtained the certain fruit, it still mostly adopt the tradition production craft. Namely it adopt the whole semi-finished product forging or castings to model and then hardfacing wearable alloy in the pick metacarpus easy abrasion part similar importing tamping pick.

国产化研究虽然已取得一定成果，但仍基本上采用传统制造工艺，即同进口捣镐一样采用整体毛坯锻造或铸造成型，然后在镐掌易磨损部位堆焊耐磨合金。
