The first is a pair of planets , each about the mass of Jupiter , that whirl around their home star15light years from Earth in perfect lockstep .

第一项是一对行星，每个大小和木星相仿，它们一前一后绕着距离地球15光年的一颗行星运行。

The results show that under pure gas flow condition , when the cross-section gas velocity of calciner ranges 6.0 ~ 8.0m / s , the pressure drop of horizontal cyclone separator varies in 80 ~ 200Pa , and the pressure drop of whirl separator is around 600 ~ 1180Pa .

研究结果表明：空载下分解炉截面风速为6.0～8.0m/s时，卧式旋风筒的压力损失约为80～200Pa，旋流分离器的压力损失约为600～1180Pa；
