1) Sylvester resultant
Sylvester结式
1.
The remainder sequence of two polynomials is first obtained using the column elementary transformation of the matrix,and then the relation between the Sylvester resultant and the one of the neighbor terms in the remainder sequence is established.
最后根据这个关系导出一种计算Sylvester结式的方法。
2) Sylvester resultant elimination
Sylvester结式消元法
3) Sylvester inequality
Sylvester不等式
1.
By using matrix-blocking,this paper gives the necessary and sufficient condition for the equatity sign in the Sylvester inequality,and the sufficient condition for the equatity sign in the Frobenius inequality,and the corresponding algorithm and example are also given.
利用矩阵分块,给出了Sylvester不等式等号成立的充要条件和Frobenius不等式等号成立的充分条件,并给出了判别等号成立的算法算例。
2.
In particular, extremely concise proofs for famous results such as Frobenius inequality and Sylvester inequality are obtained, and some related problems and facts in linear algebra, including properties of matrices with full column rank, and discussed.
特别是,给出了Frobenius不等式,Sylvester不等式等著名结果的极其简洁的证明,据此探讨了线性代数中有关问题和实例,包括列满秩矩阵的特点等。
4) sylvester formula
Sylvester公式
5) Sylvester-Blumenthal determinant
Sylvester-Blumenthal行列式
6) Sylvester's law

补充资料:长藤结瓜式灌溉系统
在输水、配水渠系上连接有水库、池塘等调蓄水量设施的灌溉系统。系统中的渠道象瓜藤,水库、池塘象藤上的瓜,故称长藤结瓜式灌溉系统(见图)。中国南方丘陵山区建有许多这种形式的灌溉系统。它与单纯的引水灌溉系统相比,优点是:可以把非灌溉季节的河水和灌水低峰期多余的渠水,以及沿渠的坡面径流等,引入水库、池塘存蓄起来,供灌水高峰期使用,弥补引入水量的不足,从而提高河水坡水的利用率,并可较充分地利用渠道的引水能力,达到扩大灌溉面积和提高抗旱能力的目的。缺点是:修建这种灌溉系统的蓄水设施,常占用一些土地,耗费一定的建设和管理养护费用,蓄起来的水也会有一部分蒸发渗漏损失。
