低真空阶段近似常抽速抽气，如不考虑管道影响，考虑漏放气时，抽气时间的计算公式为：t=()。式中：V是容器的容积(m³);Sp是真空泵的抽速(m³/s);PO是抽气开始时容器内的压强(Pa);P是抽气终了时容器内的压强(Pa);Pu是真空系统所能达到的极限真空度(Pa);Se是真空泵对容器的有效抽速(m³/s);t...
Assuming you have the clock via the PLL running at 48MHz then for 57600 baud it gives DLL=52, DLM=0 and a real baud rate of 57692 baud. Because the UART resynchronises every start bit, anything that's less than half a bit out in 10 bits will work!10 bits at 57600 baud = 173.6...
