style="text-indent:25px">我們知道水的導(dǎo)電性能，與水的電阻值大小有關(guān)，電阻值大，導(dǎo)電性能差，電阻值小，導(dǎo)電性能就良好。根據(jù)歐姆定律，在水溫一定的情況下，水的電阻值R大小與電極的垂直截面積F成反比，與電極之間的距離L成正比： R=ρ＆#183;L/F 式中ρ為電阻率，或稱比電阻。電阻的單位為歐姆（歐，代號Ω），或用微歐（μΩ），1Ω等于106μΩ電阻率的國際制（SI）單位為歐米（Ω＆#183;M）。如果電極的截面積F做成1CM2，那么電阻值就等于電阻率。水的電阻率的大小，與水中含鹽量的多少，水中離子濃度、離子的電荷數(shù)以及離子的運(yùn)動速度有關(guān)。因此，超純水電率很大，超純水電阻率就更大,也就說水越純，電阻率越大。超純水水質(zhì)當(dāng)中含銅在8ppb以上，就會引起發(fā)光變色的現(xiàn)象。舟山超純水哪家好</p><p
