After experimented, the time transfer uncertainty of multi-channel GPS receiver is less than 4 ns ( elevation is more than 40 degree) in the condition of the comparision of common-view and common-clock on zero base line. 经测试证明多通道GPS接收机零基线共钟共视时间比对的不确定度小于4ns(仰角40°),与国外报道基本相同。
When the tail oxygen concentration was up to 7%, the speed of mass transfer of oxygen had no effect on the reaction; the varieties oxygen concentration was zero series to the oxidation speed. 当尾氧浓度大于7%时,氧的传质速率对反应没影响,且氧浓度变化对氧化反应速率的影响为零级。
