It does not limit the accuracy of single measurements, of nonsimultaneous measurements, or of simultaneous measurements of pairs of quantities other than those specifically restricted by the principle. Even so, its restrictions are sufficient to prevent scientists from being able to make absolute predictions about future states of the system being studied. The uncertainty principle has been elevated by some thinkers to the status of a philosophical principle, called the principle of indeterminacy, which has been taken by some to limit causality in general.
不限制單一測量的準(zhǔn)確度,也不限制非同時測量的準(zhǔn)確度,非不確定原理要求的成對的量,同時測量也不限制準(zhǔn)確度。即使如此,科學(xué)做出所研究的系統(tǒng)的關(guān)于未來狀態(tài)的絕對預(yù)言,它的限制是充足的。不確定性原理被一些思想家引申去研究哲學(xué),稱為模糊原理,被用于限制通常的因果關(guān)系。
很顯然,不確定性原理不限制單一測量的準(zhǔn)確度,但并未肯定單一測量沒有門限,而且作出了“關(guān)于未來狀態(tài)的絕對預(yù)言,它的限制是充足的”,因此說“單個量的測量,沒有測量準(zhǔn)確度的門限,即測得值可以無限制地接近真值,因而真值是可知的”是沒有科學(xué)依據(jù)的,任何測量都會有門限,只是目前測量不確定度遠遠沒有到這個門限
