The study focuses on "value diversity", and explores it step by step with a route of "Review -Rethink and Criticism -Construction and Transcendence -Application"From a historical perspective, the study reviews and summarizes western educational evaluation theories and technology development, describes evaluation methods of so-called first three generations evaluation methods, and analyzes historical critique of them, including their failure to accommodate value-pluralism, a tendency towards managerialism, and the overcommitment to the scientific paradigm of inquiry; and then further points out that the fourth generation evaluation methods can be introduced for their effective response to problems of value-pluralism. The study focuses on the characteristics and ideology of the fourth generation evaluation theory; based on which, the research work investigates the social and cultural foundations of education evaluation theory and technology formation development from the dimension of the evolution of values foundation, the impact of social ideology and methodology conversion.

This paper first analyses and summarizes the ststus quo and evolution trend of encryption, some common used cryptograph are introduced, including the algorithms used in symmetric cryptosystem and asymmetirc cryptosystem. We describe the theory of each algorithms and compare the elliptic curve cryptosystem with the other two asymmetric cryptosystems to show the advantages of this algorithm. Second, the principle of ECC is discussed, including the math foundation of ECC, basic conception of elliptic curves, constructiong idea of ECC, operation on the elliptic curve and so on. Third, the current attacks of ECC were analyzed deeply, and an algorithm based on limited prime number field was constructed. We analyzed its realizability in theory, and implement it by using certain function of MIRACL software package. Latter half in this paper, the implementation model of a simple elliptic curve encryption system which based on GF has been introduced. The paper also put a deep analysis on the algorithm of point addition and point multiplication.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
