A method of establishing a communication path from a first legal entity in a data communication network comprises the steps of providing at least one private reference point comprised in the data communication network and establishing a communication path from the first legal entity to the private reference point. The method further comprises verifying the authentication of the first legal entity relative to the private reference point from the first legal entity and still further a method of establishing communication from the private reference point to a second legal entity through the data communication network without disclosing the identity of the first legal entity without disclosing the identity of the first legal entity.

The invention provides a horizontal high-temperature vacuum coating production line, which comprises frames, vacuum buffer tank bodies, vacuum coating tank bodies, substrate frame delivery mechanisms and automatic loading and unloading piece mechanisms. The vacuum coating tank bodies are arranged in the middles of the upper parts of the frames; two groups of vacuum buffer tank bodies are arrangedon the frames at the two ends of the vacuum coating tank body respectively; pneumatic rotary plate valves are arranged between the vacuum buffer tank bodies and between the vacuum buffer tank body and the vacuum coating tank body; the two ends of the frames are provided with the automatic loading and unloading piece mechanisms; the lower parts of the frames, the bottoms of the vacuum buffer tank bodies and the bottoms of the vacuum coating tank bodies are provided with the substrate frame delivery mechanisms which are connected with the automatic loading and unloading piece mechanisms; and target guns and heaters are also arranged in the vacuum coating tank bodies. The production line has the advantages of reasonable structure, stable glass delivery, high temperature resistance, suitability for performing high-temperature vacuum coating on the surface of large-size glass, industrial production, and capability of replacing the conventional vertical vacuum coating production line and realizing large-size glass high-temperature vacuum coating.

The invention discloses a method for improving microspore embryogenic rate of wuta-tsai. The method comprises the following steps: carrying out mixed culture to buds easy in embryogenesis and buds difficult or weak in embryogenesis, extracting by virtue of a B5 extracting solution, and inducing embryogenesis in a 1 / 2NLN-13 culture medium. Compared with the single culture of the prior art, the method disclosed by the invention can be used for effectively inducing the embryogenic rate of the variety difficult in embryogenesis and for improving the embryogenesis rate and the plant regeneration rate of the variety weak in embryogenesis, and the technical problem that the variety weak in embryogenesis is low in embryogenesis rate and embryogenesis genotypic ratio can be solved; meanwhile, the technical obstacle of generating plants from the variety difficult in embryogenesis by virtue of microspore culture is solved; and the method disclosed by the invention is significant in the microspore culture of the wuta-tsai.

The invention provides a hole-pitch-adjustable drilling device. The device comprises a supporting frame, a first drilling mechanism, a second drilling mechanism, an oil cylinder and a linkage mechanism, wherein the first drilling mechanism and the second drilling mechanism are arranged on the supporting frame in a sliding way; and the oil cylinder is arranged on the supporting frame, is positioned between the first drilling mechanism and the second drilling mechanism and is used for driving the first drilling mechanism and the second drilling mechanism to slide close to each other or far away from each other on the supporting frame by using the linkage mechanism. In the hole-pitch-adjustable drilling device provided by the invention, the two drilling mechanisms are integrated on the supporting frame, hole pitch can be adjusted through the linkage mechanism, and the operation of two holes can be finished at a time, so that the working efficiency of punching is improved; and the operation can be finished by operating the device only by one operator, so that the device is conveniently and reliably operated, and the problems of mutual interference and avoidance of the two drilling mechanisms are solved.

The invention discloses an automatic grinding and mixing device for an ultrahard material. The automatic grinding and mixing device comprises a base and a supporting barrel, wherein a cover plate is arranged at the top of the supporting barrel; a hard alloy mortar is arranged at the bottom of an inner cavity of the supporting barrel; a nut is arranged in the center of the cover plate; a screw rod is screwed in the nut; the bottom end of the screw rod extends into the supporting barrel and is connected with a rotary supporting plate; the rotary supporting plate is downwardly and fixedly connected with an upper hinge; the upper hinge is downwardly hinged with a lower hinge; the lower hinge is connected with a hard alloy grinding head; the top end of the screw rod extends out of the nut and is connected with a positive and negative rotation motor; the bottom of the positive and negative rotation motor is fixedly connected with a motor supporting plate; one side of the motor supporting plate is connected with a guide sleeve; an anti-rotation guide rod glidingly penetrates through a through hole of the guide sleeve; the bottom end of the anti-rotation guide rod is fixedly connected to the top of the cover plate. In short, the labor intensity of an worker can be reduced, an actual state of a manual grinding and mixing process can be automatically simulated, the defect of high material uniformity difference caused by the manual grinding and mixing process can be avoided, and the technical obstacle in producing high-quality diamond and cubic boron nitride polycrystalline composite sheets can be overcome.

The invention discloses a method for removing ammonia nitrogen from ionic mixed rare earth feed liquid. The method is characterized by comprising the following steps: decomposing ionic mixed rare earth to obtain mixed rare earth feed liquid; adding complex oxidants into the mixed rare earth feed liquid in batches according to the mass ratio of N oxidizing agent to N<NH4+> being equal to (2-30):1, and performing tail gas treatment on produced gas; filtering the feed liquid subjected to ammonia nitrogen removal, so as to obtain the clear rare earth feed liquid. The method has the advantage that the content of ammonia nitrogen is reduced from the source, so that a subsequent sewage ammonia nitrogen treatment process is avoided, the sewage treatment cost is reduced, and treatment up-to-standard release is achieved.
