IE has experienced nearly a hundred years of occurrence and development of applications and promotion, IE has now become an independent discipline. First of all we must understand the nature of IE and the basic content, step by step, and gradually. We know that human beings make and process natural resources (such as wood, ore, water, stones, etc.) and raw materials (such as steel, building materials, chemical raw materials, etc.) to meet the needs of humankind’s survival.
