Abstract: A device for simulating high-frequency current propagation of partial discharge of a GIL/GIS is disclosed. The device comprises a casing, a busbar cavity, an adjustable impedor, a first metal support, a second metal support, a third metal support, and a high-frequency current sensor. The first metal support and the second metal support are separated by an insulating support, the third metal support has an end connected to the second metal support, as well as an end connected to a grounding grid, and the adjustable impedor is formed by an adjustable resistor and an adjustable inductor which are connected in series, and is connected in series between the first metal support and the second metal support through a wire.

Abstract: A method for the enzymatically catalyzed synthesis of a diol from an amino acid includes enzymatically hydroxylating the amino acid, enzymatically deaminating the amino acid, the deamination resulting in the formation of an oxo group at the position of the amino group, enzymatically decarboxylating the amino acid, and enzymatically hydrogenating the oxo group resulting from the deamination reaction.

Abstract: Automatic remove equipment for disaster blooming marine organisms of sea water intake channel belongs to the field of marine environmental engineering and equipment. The equipment comprises a cod-end of collecting net, a saw blade at the end of net, a fixation and support system, a submersible spiral pump, a transport pipe system, a separating system on coast and floats. The equipment collects the disaster blooming marine organisms in the sea water channel into the bottom of a cod-end of collecting net, and cuts and decomposes the collected disaster blooming marine organisms by using a saw blade at the end of net under the combined action of the water flow power and the suction pressure of a submersible spiral pump. Fragments after cutting are sucked by the submersible spiral pump and delivered to a coast, and are subjected to solid-liquid separation by a separating system on coast and then are centrally disposed.

Abstract: The present invention is a portable pedestal pan—a specially designed structure that is used in places without interior bathrooms or where going to the bathroom is inconvenient (such as outdoors, in hospital wards, and in the vehicle) and that is easily portable. The present invention comprises a top board, a vertically retractable supporting mechanism that is set under the top board, wherein the supporting mechanism is equipped with a caging device for locking upon retraction. The supporting mechanism optionally has a bottom board 14 that is set underneath the supporting mechanism and is connected to it. The top board is optionally a ring with a hole in the middle. When the invention is used, the supporting mechanism under the top board is vertically unfolded, and is locked by the caging device, and a scrap bag is sleeved onto the top board. After use, the scrap bag is taken off. The supporting mechanism is folded. The present invention is easy to carry and reuse.
