  1. Sixties primers were used for dna amplification and a total of 237 amplification products range from 450bp to 2500bp were generated. a similarity matrix for all pairwise comparisons was calculated using nei and li ' s formula and then transformed to distance matrix. dendrograms were constructed by applying unweighted pair - group arithmetic average ( upgma ) and neighboring - jointing cluster analyses using the phylip software

    在第二部分，應用改進的ctab法提取了石蓴屬和滸苔屬各3個種及作為對照的剛毛藻的基因組dna ， 60個引物被用於擴增，共獲得237個片段大小在450 - 2500bp之間的擴增片段，依據nei和li （ 1979 ）的公式計算出樣品成對比較的相似性距陣並換算成遺傳距離，應用phylip軟體包，按照upgma法和n - j法分別構建聚類圖。
  2. Evading risk in financial trading market cries for pricing options to a nicety. asian option, as the most flourish options in the finace market, the pricing has been focused on always. the exact pricing formula for the geometric average asian option had existed, but as to the european - style arithmetic average asian option, due to the dependence structure between the prices of the underlying asset, no analytical formula exists. on the hypothesis that the market is frictionless and without transaction costs 、 on the base of b - s ’ s and in the binomial tree model, we provide several algorithms for computing an accurate value of the european - style arithmetic average asian option. following rogers and shi and by jensen ’ s inequality, many different upper and lower bounds are provided ; meanwhile a formula have got by the comonotonicity and approximating the distribution function. all of the algorithms are easy for programming. with the development of computer, more accurater price can be computed quickly. and numerical example proved that these algorithms are very accurate

    對于幾何平均亞式期權它的定價相對簡單，已經給出了定價公式。對于算術平均亞式期權，它的未定權益具有軌道依賴特性，一直沒有得到它的定價方程的解析解形式。本文基於對市場是無摩擦且在沒有交易費用的情況下，在b - s模型下，利用二叉樹模型給出了算術平均亞式期權定價方法;並總結了利用jensen 』 s不等式給出的各種不同情況下的上下界;同時應用共單調性和近似分佈函數的方法也給出了算術平均亞式期權價格的近似公式。
  3. This recognition method integrates traits of nearest neighbor method and k - neighbor method. its basic principle is to improve recognition reliability with tow additive thresholds. in addition, ternary threshold neighbor recognition method ’ s fast arithmetic based on c - average clustering and huffman tree is put forward

    2 .本文在經典統計模式識別方法的基礎上，結合了最近鄰識別法和k近鄰識別法的特點，給出一種三閾值近鄰識別方法，其基本原則是在尋找未知樣本的近鄰時，通過附加閾值的限制，進一步提高識別的可靠性。
  4. In the research of flooding arithmetic, at first, we analyse the flooding efficient, robustness by the 3 - neighbor, 4 - neighbor and 6 - neighbor ’ s wsn. so we extend to the n - neighbor ’ s wsn. we give the formula about area of wsn ’ s deploy, count of wsn ’ s node, max distance of communications and average of neighbor ’ s count, and validate this formula by the simulate program. in the last, we analyse the flooding arithmetic ’ s lose rate, data efficient rate, energy efficient rate, network life, delay time by the simulate program

    在洪泛演算法研究中，首先針對3 -鄰點、 4 -鄰點和6 -鄰點的無線傳感器網路分析了洪泛效率、網路健壯性，然後推廣到n -鄰點的無線傳感器網路中，並給出無線傳感器網路部署面積、節點個數、最大傳輸距離、和平均鄰點數之間的經驗公式，並用模擬程序進行了驗證。
