Abstract: This application discloses a power distribution cabinet which includes a cabinet body, a first air duct assembly, and a second air duct assembly. The first air duct assembly is disposed outside the cabinet body, and the first air duct assembly is disposed on the first side wall of the cabinet body. A projection of the first air duct assembly on the first side wall covers the first air vent and the second air vent. A first circulation space is formed between the first air duct assembly and the first side wall. The first circulation space communicates with an internal space of the cabinet body through the first air vent and the second air vent. The second air duct assembly is disposed inside the cabinet body, and the second air duct assembly forms a second circulation space. The second circulation space communicates with the first air vent.

Abstract: A transportable folding door includes a folding door body and a door handle bar arranged on a side of the folding door body. A handle is arranged on the door handle bar. The folding door body is made of a flexible polyester material. The door handle bar is formed by splicing a plurality of supporting bars, and a connecting assembly is arranged between two adjacent supporting bars. Connecting holes are separately formed at a connection of the two adjacent connected supporting bars, and the connecting assembly is fixedly connected to the connecting holes of the two adjacent connected supporting bars. The connecting assembly includes a clamping bar with a U-shaped cross section, connecting columns, and a connecting piece. Both ends of the clamping bar are separately provided with receiving holes corresponding to the connecting holes on the two adjacent connected supporting bars.

Abstract: The present application provides a method and a device for synchronizing a high-speed quantum key generation system, wherein the method comprises: a sender aligns first light pulse of signal light with that of synchronization light, and controls the signal light not to emit light during N consecutive periods within each period Tt of the synchronization light; a receiver performs time measurement on received signal light pulse, the signal light emits light at the remaining corresponding positions except the N consecutive non-emitting positions in each period Tt, the emitting positions can join the statistical process of T1i and T2i, the statistical time is reduced by several orders of magnitude relative to the existing method of only sending single signal light pulse, and the statistical process can be completed in a few hundred milliseconds or even shorter.
