Abstract: A method for stabilizing a neutralization slag of uranium associated zirconium and zirconia, and a stabilization agent used therein are disclosed. The stabilization agent includes the following components in parts by weight: a pretreatment agent of 2-8 parts, anhydrous calcium chloride of 2-6 parts, an adsorbent of 3-5 parts and a stabilizer of 4-9 parts. The stabilization agent is used to stabilize the uranium that is existed in the neutralization slag in a waste slag. The method includes the following steps: the pretreatment agent is used to alkalize and disperse the neutralization slag; soluble calcium salt is added to cement the neutralization slag; and the adsorbent and the stabilizer are used as a composite material to passivate the neutralization slag. The method has low cost, fast effectiveness, simple process, easy operation, and long-term stable remediation efficiency, which can be applied to the treatment and disposal of associated radioactive waste residues.

Abstract: A DC/DC converter includes a soft start overshoot prevention mechanism. The DC/DC converter includes a DC/DC conversion circuit, an overshoot detection apparatus, a pulse width modulation generator, an error amplifier, and an integration circuit connected to an output port of the error amplifier. The integration circuit is configured to perform integration processing on a difference between a reference voltage and an output voltage of the DC/DC conversion circuit, and control an amplitude of an amplified voltage that is input by the error amplifier to the pulse width modulation generator. The overshoot detection apparatus obtains an operating status parameter of the DC/DC converter, and controls, when the operating status parameter of the DC/DC converter meets an operating status parameter requirement, the integration circuit to discharge.
