摘要
在统计力学中 ,信息熵是概率或混乱度的度量。农业技术系统中各种技术要素的随机杂乱分布有碍生产力的提高 ,必须通过技术控制使要素分布集中到概率极小的选择上去 ,这是一个降低系统信息熵的过程 ,随之会伴随系统热力学熵的降低。在信息约定条件下 ,信息熵有评价技术系统整体性质的作用 ,并可用于系统中某些技术要素与其效果相关性的分析 ,因而有指示技术改革方向的意义。
In statistical mechanics, information entropy is defined as the measurement of the degree of order.This idea is relevant to the distributive probability of technical factors in the total technical system.It is a process that agrotechnical system passes over from large information entropy to minor states which would obtain information and correspond to the diminishing of thermodynamic entropy of the system.This is a new way for the study of the total character of technical system.
