常見例句雙語例句What is the unit of potential difference? Volt.勢能差的單位是什麼，伏特。They work because certain materials, such as bismuth telluride, generate an electrical potential difference within themselves if one part is hotter than another.它們之所以能起作用是因爲 一般的 材料，比如碲化鉍，如果其中一部分比另一部分熱，內部就會産生電位差。Metallic tin is not electropositive enough compared with the electronegativity of its oxide to deliver a useful potential difference.比起鉛來，金屬錫的電正性沒有二氧化錫的電負性強，所以無法産生可用的電位差。ecocn.org原聲例句What people did is they said let's define a unit of energy that represents a unit charge accelerated across a unit potential difference, and let's call that the electron volt.前人們所做的就是他們說讓我們確定,一個能量單位用來代表一單位電荷,加速穿過形成的一單位電勢差，我們叫它電子伏特。麻省理工公開課 - 固態(tài)化學導論課程節(jié)選That potential difference is generated by the movement of ions, principally sodium and potassium across the membrane.電勢差是由離子運動造成的,特別是鈉和鉀的跨膜運動耶魯公開課 - 生物毉學工程探索課程節(jié)選What is the unit of potential difference?
