Many countries are positively impelling the research and application of the Next Generation Internet (NGI). China launched a large scale IPv6 backbone network project: China Next Generation Internet (CNGI).

The present manufacturing situation of China’s thermal power generation equipment By the year 1995. development of China’s electric power industry has experienced a course of a hundred years. Over a period of the initial 50 years. China’s development of electric power was slow. At the time of 1949, the total installed capacity in China was 1,850 MW and the electricity generated was only 4.3 billion kWh. During the past 46 years after 1949, her展开更多

According to the available documents, it can be found out that, among the first generation of new China leaders, MAO Ze-dong, ZHOU En-lai, LIU Shao-qi, ZHU De and DENG Xiao-ping made more statements on the integration of CM and WM due to different division of labor and other historical reasons. This paper will focus on the issue to study the emergence, formation and development of their thoughts on the integration of CM and WM and analyze its process and significance, so as to enlighten the current integration of CM and WM, and even the world＇s integrative medicine.展开更多
