在人类社会中，知识的积累、传播和借鉴，是人类文明的重要表现，也是人类基于知识的继承和发展向更高级形态进步的重要条件。在人类认识世界、改造自己的伟大进程中，包含了一种知识产生和吸收的过程。有人把表现这一过程中的思维活动及其结果的物化因素称作“情报流”。专业 In human society, the accumulation, dissemination and reference of knowledge are the important manifestations of human civilization. They are also an important condition for the progress of human inheritance and development based on knowledge to a higher form.

The physical and chemical factors that characterize the thinking activities and their outcomes in this process are called “intelligence flows.” profession
