【判断题】液体吸收法脱水Dehydration by liquid absorption采用吸湿性较强的液体与天然气接触,气中含水被吸收,吸收了水分的液体经处理再生后重复使用。The liquid with strong hygroscopicity is used to contact with natural gas, and the water in the gas is absorbed.天然气工业...
【简答题】一个容器内装有水,使水(K=2000MPa)的体积减小1%,压强需要增大多少? The volume of water in a container is reduced by 1%, so how much does the pressure need to increase?(K=2000MPa)
【判断题】干涉法interferometry原理:利用光纤受到所检测物理场感应,如,温度、压力或振动等,使导光相位产生延迟,经由相位的改变,造成输出光的强度改变,进而得知待测物理场的变化。Principle: the optical fiber is induced by the detected physical field, such as temperature, pressure or vibrat...
【判断题】气体在流道中经过突然缩小的断面(如管道上的针形阀、孔板等),产生强烈的涡流,使压力下降,这种现象称为节流。如果在节流过程中气体与外界没有热交换,就称为绝热节流。Gas in the flow channel through the sudden reduction of section (such as the needle valve on the pipe, orifice plate, et...
