Since the other forces work by exchanging carrier particles, we assume that gravity does too and call the carrier the graviton.
采用了离心力加快沉降速度,粒子的沉降速度大,均匀低速的假设条件不再满足,理论计算模型和实际情况偏差大。
Thirdly, because of the centrifugal force, particles in the magnetorheological fluid sediment at a speed faster than the assumed low and uniform speed in the theoretical sedimentation model.

结果表明,复合乳胶粒子的形成过程与假设的演化模型基本吻合。
The result showed that the development of composite latex was mostly in agreement with the assumed evolution pattern.
有证据表明宇宙中锂元素的含量比预计要少,所以假设的超级弱相互作用重粒子可以作为一种方法解释这种差异。
There is some evidence that the universe has less lithium than expected, and the super-WIMP hypothesis is one way to explain the discrepancy.
