It consists of metallic mercury dropping at a steady rate from a capillary tube . 它由金屬汞從毛細(xì)管中以穩(wěn)定速度滴下而成。
Mercury drop amplitude 汞滴振幅
When the days are short and the mercury drops , it ' s a challenge to exercise comfortably and safely 當(dāng)日常變短,溫度下降的時(shí)候,對(duì)于訓(xùn)練的舒適度和安全是一個(gè)挑戰(zhàn)。
Using mercury drop as reagent , according to different color changing time needed for different element sulfur content , the element sulphur content could be quickly determined 利用汞滴在不同含量的元素硫中變色時(shí)間不同這一性質(zhì),快速確定銹粉中元素硫的含量范圍。
