內容簡介

With the publication of Volumes III and IV we have completed our presentation of the material which we originally planned as "Volume II" at the time of publication of Volume I. We originally promised the publisher that the entire series would be completed nine months after we submitted Volume I. Well! We have listed the contents of future volumes below. We are not foolhardy enough to make any predictions.

首先將電子商務劃分為廣義和狹義的電子商務。廣義的電子商務定義為，使用各種電子工具從事商務活動；狹義電子商務定義為，主要利用Internet從事商務或活動。無論是廣義的還是狹義的電子商務的概念，電子商務都涵蓋瞭兩個方麵：一是離不開互聯網這個平颱，沒有瞭網絡，就稱不上為電子商務；二是通過互聯網完成的是一種商務活動。

數學物理以研究物理問題為目標的數學理論和數學方法。它探討物理現象的數學模型，即尋求物理現象的數學描述，並對模型已確立的物理問題研究其數學解法，然後根據解答來詮釋和預見物理現象，或者根據物理事實來修正原有模型。“數學物理”，是數學和物理學的交叉領域，指應用特定的數學方法來研究物理學的某些部分。對應的數學方法也叫數學物理方法。包括微分方程、作用量理論等多方麵。
