压力抑制系统 pressure suppression system

末段终点流量增大时，末段起、终点压力都要减小。相反，终点流量减小时，末段起、终点压力都要增大。When the terminal flow increases, the terminal pressure should be reduced. On the contrary, when the terminal flow decreases, the terminal pressure increases.

5、本实验是把气压的压力变化通过扩散硅压力传感器转化为电压的变化，微弱的电压信号经差动放大器放大后，用毫伏表观察电压的变化，并进行数据分析处理和人体血压的测量。 In this experiment, the pressure change of air pressure is transformed into the change of voltage through the diffusion silicon pressure sensor. After the weak voltage signal is amplified by the differential amplifier, the change of voltage is observed with a millivoltmeter, which will be used for data processing and blood pressure measurement.

气体的粘度随压力增高而增高。在低压时，气体粘度随温度升高而增加，随着压力的增加，温度升高对粘度增大的影响越来越小，当压力很高时（100×105Pa以上），气体粘度随温度升高而降低，明显表现出类似于液体的性质。Table 1-13 shows the dynamic viscosity of methane at different pressures and temperatures. It can be seen from the table that the viscosity of gas increases with the increase of pressure. At low pressure, the gas viscosity increases with the increase of temperature. With the increase of pressure, the influence of temperature increase on the inc
