table of distances
解釋
距離表-
The nearest neighbors of each individual and the distances between each individual - neighbor pair in elaeagnus mollis communities were obtained by using the nearest neighbor ' s analysis. based on the primary results above, the spatial pattern and interspecific segregation in the communities were studied by x2 test with a subtable method of a n n nearest - neighbor contingency table
應用最近鄰體法判定每個個體的最近鄰體植株，得到每個基株-最近鄰體種對的距離，進而採用n n最近鄰體列聯表的截表法，研究了翅果油數群落的種間分離。 -
Second, combining with the construction principle of geometry - goppa codes, we present a kind of new algebraic - geometry code by using the properties of algebraic curves on finite fields. we determine the value of the code - length n and d imension k, and the lower bound of the minimal distances of the new algebraic - geometry code. the new algebraic - geometry code have the following characteristics : ( l ) the new code is the generalization of geometry - goppa codes and the algebraic - geometry code constructed by chaoping xing and san ling in 2000 ( 2 ) compared with brouwer ' table of the best known codes, we find more new codes, there are at least 60 new codes under two - dimension cases
其次，結合幾何goppa碼的構造原理，利用有限域上代數曲線的特點來構造代數幾何碼，確定了新的代數幾何碼的碼長n和維數k的取值，給出了最小距離d的下限，這類碼的特點是： （ 1 ）新的代數幾何碼是幾何goppa碼和新加坡國立大學chaopingxing和sanling在2000年所構造的代數幾何碼的推廣； （ 2 ）這類碼中有許多種碼的參數優于brouwer碼表，僅二維情形時，就有60多種碼優于brouwer碼表。 -
