摘要
误差传播定律是基于显函数的,而在实际工程中,不少变量不能由另一些变量以显函数形式表示,只能是以隐函数的形式表示。为此,基于隐函数,给出了误差传播定律的一般形式,并应用于线路工程,结果表明该方法是可行和有效的。
The error spread law is based on the obvious function. However, in practice, many variables can not be expressed by the obvious function from other variables, only can be expressed by the latent function. Here, the common form of error spread law based on latent function is presented and applied to the line engineering. It is shown that this method is feasible and resuhful.
