Those more-refined analyses have not seen the hypothetical new particle, so for some reason it must not decay into bottom quarks.

那些更精细的分析并没有发现这种假设的粒子，所以，也许它因为某些原因并不会衰变成底夸克。

The result shows that the bottom of each potential well is not where the particle stays. The peak values of probability locate near the bottoms on side walls.

结果表明不对称势场中阱底并不是粒子基态稳定存在区域，最高概率密度分布位于平缓阱壁。

Starting from the force balance on a solid particle, equations with dimensionless groups were also developed to calaulate the critical settling velocity of particles at the reactor bottom.
