The world modern pharmaceutical industry started in the period of international economic revival after the Second World War. The huge social and economic benefits of drugs stimulated the pharmaceutical industry to flourish at a high speed from 1950s to 1970s, and new drugs in various therapeutic fields were coming out continuously. After entering the 1990s, 1991-1995 was the low tide of world economic development. The economic recession has spread to almost all industrialized countries in the world, and the economies of the old industrialized countries, the United States and Britain, have even experienced negative growth. Although the pharmaceutical economy is also affected by the recession and the growth rate has slowed down, it still maintains a good level. The world pharmaceutical economy increased by 13.8% annually in the 1970s and 13.5% annually in the 1980s. Although the average annual growth rate decreased to 9.5% in the 1990s, the global pharmaceutical output value increased by 11.6% in 1995. It is expected that it will continue to develop steadily at an average annual growth rate of 7% in the coming period. The total sales of the world drug market was US $301 billion in 1998 and is expected to reach US $680 billion in 2010. Facing the promising pharmaceutical market, developed countries have increased investment in pharmaceutical R & D and formulated corresponding countermeasures to meet the increasingly fierce competition in the international pharmaceutical market. At present, the world pharmaceutical market is divided into the United States, the European Union and Japan. Similarly, in the competition of scientific and technological competitiveness of the pharmaceutical industry, it is also a tripartite pattern of the United States, the European Union and Japan. However, the rapid development of the pharmaceutical industry can not cover up its exposed problems. For example, the enterprise centered technological innovation system has not been formed, the pharmaceutical circulation system is not perfect and other factors are hindering the sustainable development of the pharmaceutical industry. On this basis, research on traditional Chinese medicine and natural medicine; The emergence of industrial trends such as biopharmaceutical technology points out the direction for the development of the industry. As we all know, traditional Chinese medicine research and biopharmaceutical have high requirements for the environment. The working environment of extreme temperature and pressure tests the comprehensive performance of the burner.
