The invention discloses a configuration method for userspace I / O (UIO) equipment. The method comprises the steps that a message path between a kernel mode and a user mode is created, wherein a user mode configuration proxy and a kernel mode configuration proxy can both access an inner memory of the message path; corresponding kernel mode pseudo equipment is created for the userspace I / O (UIO) equipment; the kernel mode configuration proxy receives a configuration request of an equipment configuration tool for the kernel mode pseudo equipment; the kernel mode configuration proxy sends the configuration request to the user mode configuration proxy through the message path; the user mode configuration proxy receives the configuration request from the message path and invokes a corresponding UIO equipment drive to execute a corresponding configuration command. The invention further discloses a device corresponding to the method. By means of the configuration method and device for the userspace I / O (UIO) equipment, on the promise of not modifying the user mode configuration tool, the UIO equipment is directly configured, and the development cost is greatly reduced.

The invention relates to a street lamp with a high-power light-emitting diode (LED) single polycrystalline chip die set, which comprises a shell body formed by a back shell and a surface shell, a light field photomask, a high-power LED single polycrystalline chip die set, light scattering lenses, and a heat radiating device provided with an arc-shaped heat radiator and a superconductive heat pipe, wherein the surface shell is provided with a first window; the light field photomask is arranged in the first window of the shell body; the light scattering lenses are solid core lenses taking the flat bottom surface as the light incidence surface and are arranged in the bottom mouth in the light field photomask; the flat bottom surfaces of the light scattering lenses tightly contacts with the silica gel on the surface of the high-power LED single polycrystalline chip die set without gap so as to form a batwing rectangular light field distribution curve flux by utilizing a primary light source; and the heating radiating device is arranged on the hogged part of the back shell. The high-power LED single polycrystalline chip die set is taken as a light source and is matched with the light field photomask and the single light scattering lens to reach the requirement of the batwing rectangular light field distribution curve flux street lamp by using the primary light source; the brightness uniformity is enhanced, and the lighting effect is good; the shell body is prepared by adopting ultraviolet-resistance aging-resistance reinforced and toughened plastics; the weight is greatly reduced; and the street lamp is conveniently installed and safely used.

The invention relates to a maximum extension distance quantified prediction method of a near-shore underwater fan flood sedimentation unit body. Based on a near-shore underwater fan sedimentation formation mechanism and a water tank sedimentation simulation experiment, plane and profile distribution characteristics of a near-shore underwater fan glutenite sedimentation unit body are determined, the longitudinal change rule of the thickness of the flood sedimentation unit body is researched, and a theoretical formula model of the thickness change of a central longitudinal profile of the flood sedimentation unit body is established; with the guidance of the distribution characteristics, determined by the simulation experiment, of the near-shore underwater fan glutenite sedimentation unit body, a practical geological body is divided into sedimentation unit bodies by means of well-seismic combination; and based on sedimentation unit body division, the boundary thicknesses of the flood sedimentation unit bodies are determined, and according to the practical well location condition on each sedimentation unit body, the maximum extension distances of the flood sedimentation unit bodies are predicted. According to the invention, the maximum extension distance of the near-shore underwater fan flood sedimentation unit body can be accurately and effectively determined, the sedimentation of a well network and the making of an exploration development scheme are effectively guided, and the well spacing efficiency in the exploration development process is improved.
