您要查找的是不是：
- 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. 引力微子一种假想粒子，被假定为引力相互作用的量子，并被推测为具有无限长寿命、零电荷和零静止质量
- Fundamental particles have an intrinsic mass known as their rest mass (those with zero rest mass are called massless). 基本粒子有个称为静止质量的内在质量（静止质量为零的粒子称为无质量粒子）。
- 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. 引力微子一种假想粒子，被假定为引力相互作用的量子，并被推测为具有无限长寿命、零电荷和零静止质量。
- have an indefinitely long lifetime, zero electric charge, and zero rest mass 引力微子一种假想粒子，被假定为引力相互作用的量子，并被推测为具有无限长寿命、零电荷和零静止质量
- zero rest mass 静止质量
- Evidently one of the main distinguishing characteristics of photon is just its zest rest mass. 显然光子的一个主要区别于其它粒子的特征就在于它的静止质量为零。
- Potential energy, as opposed to rest mass or kinetic energy, leads to gravitational repulsion. 和静止质量与动能相反，位能会使重力变成斥力。
- 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. 我们实验室于2000年开始进行光子静止质量的实验检验,并提出了扭秤调制法检验光子静止质量的实验方案。
- For a compound particle, the constituents' rest mass and also their kinetic energy of motion and potential energy of interactions contribute to the particle's total mass. 对于复合粒子来说，每个组成粒子的静止质量、动能以及交互作用的位能，都会贡献到粒子的总质量。
- The Standard Model lets us calculate that nearly all the mass of protons and neutrons is from the kinetic energy of their constituent quarks and gluons (the remainder is from the quarks' rest mass). 从标准模型可以得知，质子与中子的质量几乎皆来自夸克与胶子的动能（其馀的质量则来自夸克的静止质量）。
- A cloud is a mass of vapor in the sky. 云是天空中的水汽团。
- The mercury dived to ten below zero. 温度突然下降到零下10度。
- The rest mass and the structure of a photon 光子静质量和光子结构
- The soldier rigged up a shanty for a night's rest. 士兵们临时胡乱搭起了一间小屋过夜。
- The slide cut off the valley from the rest of the world. 山崩切断了这个山谷与外界的联系。
- Now, men, zero in your guns at that ship. 喂，伙计们，把炮口对准那艘船。
- The rest mass of photon and neutrino was discussed using different view points and methods.The masses of black hole, nucleon, photon, particle of dark matter and Planck particle were estimated. 摘要讨论了光子、中微子（或暗物质粒子）的静质量，从不同的观点和方法对黑洞质量、核子质量、光子质量、暗物质粒子质量和普朗克粒子质量作了估算。
- It was five below zero last night. 昨夜温度是零下五度。
- He had to lie down for a while to rest his legs. 他得躺下一会儿让腿休息一下。
- I'm a little bit tired. Let's take a short rest. 我有点累了。让我们休息一会儿。
