The present application discloses a method and apparatus for processing a notification trigger message, which method and apparatus relate to the technical field of computers. One specific implementation of the method comprises: receiving a notification trigger message formed by triggering a notification, wherein the notification trigger message includes an identifier of a current push message corresponding to the notification; determining whether the identifier of the current push message exists in a message cache, and if the identifier of the current push message exists in a message cache, ignoring the notification trigger message, wherein the message cache is used for storing an identifier of a push message corresponding to a notification that has been responded to. The implementation can avoid multiple responses of a client to an identical notification.

This disclosure relates to a preparation method of a low-pH controlled-release intelligent corrosion inhibitor. The low-pH controlled-release intelligent corrosion inhibitor comprises a hydrogel with low pH responsiveness and a corrosion inhibiting substance having the capacity of corrosion inhibition. That is, a corrosion inhibiting substance is wrapped in a low-pH sensitive hydrogel. The swelling degree of the pH sensitive hydrogel may be changed according to the amounts of monomers and crosslinking agents so as to control the releasing speed of the corrosion inhibiting substance. By the soaking experiment and the measurements of electrochemical polarization curves and alternating impedance spectra, the sensitive and long-lasting features of the low-pH controlled-release intelligent corrosion inhibitor are indicated. Therefore, the advantageous effects of this disclosure lies in that: 1) the system enables the releasing speed of the corrosion inhibiting substance to be controlled by pH; 2) the system enables long-lasting effect and high corrosion inhibition efficiency of the corrosion inhibiting substance; and 3) the system has broad applicability.
