    摘要： Systems and methods for controlling humidity. Methods can include providing a chamber configured to receive objects to be sterilized; injecting a first quantity of water into the chamber; determining a pressure rise and a pressure drop in the chamber resulting from the first injection; calculating an absorption ratio (
    AR ) as the ratio of the pressure drop to the pressure rise; sensing the humidity of the chamber after the first injection to determine a first humidity value (
    RH
    chamber ); comparing the first humidity value to a pre-selected humidity value (
    RH
    setpoint ) to determine a humidity error (
    RH
    error ), wherein
    RH
    error =
    RH
    setpoint -
    RH
    chamber ; and injecting a second quantity of water into the chamber, wherein the second quantity of water is calculated based on the absorption ratio (
    AR ) and the humidity error (
    RH
    error ). Systems can perform the method; and the systems and methods can be employed in a sterilizer.
