We will, however, demand single-valuedness for it . 然而,我們將要求它的單值性。
According to the principles of physical measurement , the measurement of ground resistance do not posses repeatability and univalue . practice show that the ground resistance is an unscientific physical quantity 摘要根據(jù)物理量測量的基本原則可以看出,接地電阻的測定不具有重復(fù)性和單值性,實踐顯示,接地電阻是一個無法測定的物理量。
