常見例句A hypothetical particle postulated to be the quantum of gravitational interaction and presumed to have an indefinitely long lifetime, zero electric charge, and zero rest mass. 引力微子一種假想粒子，被假定為引力相互作用的量子，并被推測(cè)為具有無(wú)限長(zhǎng)壽命、零電荷和零靜止質(zhì)量Evidently one of the main distinguishing characteristics of photon is just its zest rest mass. 顯然光子的一個(gè)主要區(qū)別于其它粒子的特征就在于它的靜止質(zhì)量為零。Fundamental particles have an intrinsic mass known as their rest mass (those with zero rest mass are called massless). 基本粒子有個(gè)稱為靜止質(zhì)量的內(nèi)在質(zhì)量（靜止質(zhì)量為零的粒子稱為無(wú)質(zhì)量粒子）。Potential energy, as opposed to rest mass or kinetic energy, leads to gravitational repulsion. 和靜止質(zhì)量與動(dòng)能相反，位能會(huì)使重力變成斥力。A hypothetical particle postulated to be the quantum of gravitational interaction and presumed to have an indefinitely long lifetime,zero electric charge,and zero rest mass. 引力微子一種假想粒子，被假定為引力相互作用的量子，并被推測(cè)為具有無(wú)限長(zhǎng)壽命、零電荷和零靜止質(zhì)量。Our group started the experimental test of the photon rest mass in 2000, and presented a scheme of the modulation method with the precise torsion balance. 我們實(shí)驗(yàn)室于2000年開始進(jìn)行光子靜止質(zhì)量的實(shí)驗(yàn)檢驗(yàn),并提出了扭秤調(diào)制法檢驗(yàn)光子靜止質(zhì)量的實(shí)驗(yàn)方案。 返回 rest-mass
