一、可靠性的定义可靠性是指机具或零部件在给定时间内,按一定条件完成规定功能的能力,它表示机具或零部件功能在时间上的稳定程度。可靠性用有效度(或称有用度)量度,它是时间的函数。由于研究的对象是长时间使用的农机具或其零部件的有效度问题,因此通常采用时间有效度来量度其可靠性。 First, the reliability of the definition of Reliability refers to the machine or parts in a given time, according to certain conditions to complete the specified function, which means that the function of machine or parts in time stability. Reliability is measured as the degree of validity (or usefulness) as a function of time.
