The application discloses a system for safe clipboard synchronization between an isolated environment and a host computer, and belongs to the technical field of computer security and virtualization. The system comprises: a protocol proxy core module for intercepting clipboard protocol requests between the isolated environment and the host computer; a proxy entity module for creating a proxy entity on the host computer side to replace an application in the isolated environment holding clipboard ownership; a synchronization state manager module for maintaining internal and external time sequence identifiers for tracking the update sequence of the isolated environment and the host computer clipboard; and a loop check list. When the system initiates synchronization, the system records the synchronization operation in the loop check list; when a clipboard change is detected, the system identifies and filters loop events triggered by self-synchronization by comparing the loop check list; and when responding to a data request, the system determines the latest data source by comparing the internal and external time sequence identifiers. The application realizes safe, stable and reliable cross-environment clipboard synchronization.

The application provides a magnetic phase-shifting transformer based on vector magnetic circuit theory and an application method thereof. The magnetic phase-shifting transformer is composed of a target transformer magnetic circuit and a magnetic induction element matrix. The equivalent magnetic resistance of the magnetic phase-shifting transformer magnetic circuit and the equivalent magnetic reactance of the magnetic phase-shifting transformer magnetic circuit are adjusted, so that the magnetic flux phase angle of the magnetic phase-shifting transformer is continuously controlled.

By dynamically controlling the parameter configuration, combination mode and switching state of the magnetic induction element, the magnetic flux phase in the core is directly adjusted in a wide range, so that the phase-shifting of the voltage of the secondary winding of the transformer relative to the voltage of the original winding is realized, and the harmonic filtering and the reactive power compensation of the magnetic circuit are realized.

This application provides a method for the targeted reduction and resource recycling of platinum in waste liquid. A weak reducing agent with a standard electrode potential between 0 and 0.7 V is slowly added dropwise to the solution to be treated. The solution is stirred while maintaining the pH value between 1 and 3 at an environment of 30℃-60℃. 4+ Directional reduction to Pt 2+ A first reducing solution is formed; the first reducing solution is introduced into the adsorption device of the chelating resin, whereby the chelating resin can selectively adsorb Pt. 2+ This process forms a platinum-supported resin; the platinum-supported resin is then desorbed to obtain a Pt-rich product. 2+ The second reducing solution is adjusted to a pH between 4 and 6, and then a reducing agent is added to reduce Pt. 2+ The above method precipitates elemental platinum by selecting a weak reducing agent and under mild reducing conditions. 4+ Directional reduction to Pt 2+ Further Pt 2+ This method reduces the substance to elemental Pt, avoiding the problem of increased impurities in the solution caused by the reducing agent itself transforming into metal ions, as is common in active metal displacement methods.
