关于“试验信息熵”

Study on "Test Information Entropy"

从工程试验结果的随机性和不确定性出发,提出了"试验信息熵"的概念,并从目的、要求、信息传递模型和运用的数学工具等方面比较了试验信息熵和通信信息熵的异同,给出了试验信息熵和通信信息熵的数学表达式。特别提出了高可靠性成败型产品试验结果为"零失败"时试验信息熵的特殊形式。举例说明了试验信息熵在燃爆产品可靠性评估中的应用,并通过大样本试验结果验证了基于试验信息熵可靠性评估方法的实用性。

To describe the randomicity and uncertainty of engineering tests＇ result, Test Information Entropy was presented. The similarities and differences between Test Information Entropy and usual information entropy were discussed on the aspects of purpose, requirement, basic model and mathematical tool, etc. Furthermore, the Test Information Entropy of high reliability product with zero-failure was given. Two application examples of Test Information Entropy show that it is feasible for application of Test Information Entropy.
