  1. The investment of commercial real estate development has real option characteristics, because the real option method can properly deal with uncertainty, irreversibility and flexibility. in this part, the author construct a framework for analyzing the real options of commercial real estate investment decision, and analyzes the real options of commercial real estate investment decision from confirming the problem solved, analyzing the uncertain source, distinguishing the key uncertain factor, discerning the type of real options, constructing the real options option model, calculating the value of the commercial real estate, checking the result of calculation and redesigning, finds that the commercial real estate development has postpone option, expansion option, shrink option, change option, give up option. it proves that the commercial real estate has management flexibility in the development item, and the flexibility give

    由於實物期權方法可以很好地解決不確定性、不可逆性和靈活性，因而商業地產投資決策具有實物期權特性，同時從確定要解決的問題、分析不確定性的來源、鑒別關鍵的不確定性因素、識別實物期權類型、構建期權定價模型、計算項目價值、檢查計算結果和重新設計八個方面，構建了商業地產投資決策的實物期權分析框架，得出商業地產開發項目中通常存在推遲期權、擴張期權、收縮期權、轉換期權、放棄期權等期權類型，說明商業地產開發項目中具有管理和經營柔性，而這種柔性賦予了商業地產開發項目實物期權的特性。
  2. Using the theories of probability, algebra and number theory comprehensively, we investigate a class of boolean functions with three - valued walsh spectrum in the first part of this dissertation : the properties of the extended semi - bent functions, which are constructed from any two bent functions, are studied, followed by the structure characteristics of the boolean functions satisfying propagation criterion with respect to all but two vectors ; the definition and cryptographic properties of k - order quasi - bent functions are proposed whose walsh spectrum takes on only three values. some sufficient and necessary conditions are offered to decide whether a boolean function is a k - order quasi - bent function ; a special method is presented to construct the k - order quasi - bent functions, whose cryptographic properties are explored by the matrix method, which is different from the method of walsh spectrum and that of autocorrelation of boolean functions ; the application of this kind of boolean functions in the fields of stream cipher, communications and block ciphers is discussed, which shows the great importance of the fc - order quasi - bent functions ; some methodology are proposed to construct the k - order quasi - bent functions, including the complete construction by using the characteristic matrices of boolean functions, and the recursive method by two known k - order quasi - bent functions we further extend our investigation to the ring zp, where p is a prime, and the similar results are presented as far as the p - valued quasi - generalized - bent functions are considered

    本文首先綜合運用概率論、代數學、數論等基礎學科的理論知識，並以頻譜理論作為主要研究工具，對一類譜值分佈相對均勻的函數? ?廣半bent函數、 k階擬bent函數和p值k階擬廣義bent函數進行了系統、深入的研究，給出了廣半bent函數定義，並探討了廣半bent函數的密碼學性質；給出了k階擬bent函數和p值k階擬廣義bent函數的定義及等價判別條件；討論了k階擬bent函數和p值k階擬廣義bent函數與部分bent函數和p值廣義部分bent函數的關系，探討了它們的密碼學性質；給出了k階擬bent函數和p值k階擬廣義bent函數的典型構造方法，並將對k階擬bent函數的密碼性質的研究轉化到對一類特殊的矩陣的研究上；利用布爾函數的特徵矩陣原則上給出了k階擬bent函數的一種完全構造方法，還給出了從已有的p值k階擬廣義bent函數出發，遞歸構造變元個數更多的p值k階擬廣義bent函數的方法；初步探討了k階擬bent函數在序列密碼、分組密碼以及通信中的應用；給出了一類布爾函數walsh譜的分解式，並利用這類布爾函數的walsh譜分解式給出了一類近似穩定的布爾函數的構造，特殊情形下為k階擬bent函數；利用代數數論的知識考察了p值k階擬廣義bent函數的譜特徵，並給出了k階擬廣義bent函數與所有仿射函數的符合率特徵等等。
