中文拼音 [xiébiànchātú]
協變差圖
英文
covariogram-
Two indexes was calculated to estimate the best bands union for color combination, one is optimum index factor ( oif, the sum of standard deviation divided by the sum of correlation coefficient. ), the other is the determinant of the co - variance matrix. it can be seen from the result that for color combination the original optimal bands were tm 4, 3, 7 and tm 4, 3, 5, the best mixed images were mnf1, br and ndvi
以協方差矩陣行列式值和最佳指數值（組合波段標準差之和除以相關系數之和）為評價標準，得出對于tm原始波段而言，最佳的彩色合成組合是tm4 、 3 、 7和tm4 、 3 、 5 ；綜合幾種變換圖像的彩色合成的最佳組合是mnf1 、 br 、 ndvi 。Author ' s contribution to this work can be summarized as : a. provisioning of a comprehensive study on ipv4 / ipv6 and dhcpv4 / dhcpv6 b. derivation of the state transition tables / diagrams and time sequence diagrams for dhcpv6 from informal description in english c. development of an dhcpv6 server and client software package in the linux environment d. presentation of test suite planning work and definition a basic test group based on the remote test method defined by iso 9646, which is in turn used in testing the dhcpv6 software developed by the author. through comparison of the test results from sc - nctkl and a third - party company, the basic conformity between the implementation and relevant standards has been proved to some extent. finally the author gives a brief conclusion about the futher work and the prospect of developing dhcpv6
作者的獨立的工作包括：較深入地分析了ipv4 ipv6和dhcpv4 dhcpv6的差異；利用工作原理圖、狀態變遷圖表和時序圖，較完整地描述了dhcpv6客戶機服務器的狀態變遷和信息交換過程，對dhcpv6的協議實現提供了有價值的借鑒；在linux環境下實現了dhcpv6定義的服務器和客戶機軟體；研究了有關dhcpv6測試的相關技術，並以remotetest方法為背西南交通大學碩士研究生學位論文第日頁景編寫了測試控制數據，並在在實驗室環境下進行了相關的測試;為了提高測試結果的客觀性，對筆者開發的軟體委託了第三方進行測試，兩個測試結果表明，該軟體基本符合dhcpv6的正tf的相關標準。
