    摘要:

    介绍了一种实现气溶胶采样过程中维持采样流量恒定的方法,从流量监控原理、系统组成、电路设计等多个方面进行了详细论述。流量测试结果表明:在采样膜阻力增加3倍的情况下,该方法可以较好地控制采样过程中的流量,在一定范围内保持恒定,采样流量误差可以控制在3.7%以内。

    Abstract:

    A method of maintaining the rate of flow constantly in aerosol sampling process is introduced, and the principle of the rate of flow control, system components and the circuit design etc. has been discussed in detail. The flow rate test result indicated that under the condition of 3 times of filter film resistance, the method could control the rate of flow fairly good, the flow rate could be maintained in some range, and the measuring error could be controlled under 3.7%.
