信息就是情报,哪里有社会,哪里就不可缺少信息。从人类到低级微生物,都存在着信息交换的过程。按“软科学”的语言来讲,反馈就是被控制的过程对控制机构的反作用,由控制系统把信息输出去,又把其作用、结果返回来,并对信息的再输出发生影响,影响系统的实际过程或结果,起到控制的作用,达到预定的目的。具体到科学技术的研究工作中,信息来自社会、科技人才、科研成果,反 Information is intelligence. Where there is society, information is indispensable. From human to low-level microorganisms, there is a process of information exchange. According to the language of “soft science”, feedback is the reaction of the controlled process to the control mechanism. The control system outputs the information, and returns its effect and results, and affects the re-output of information and affects the system. The actual process or result of the exercise plays the role of control to achieve the intended purpose. In specific scientific and technological research work, information comes from society, scientific and technological talents, and scientific research achievements.
