A method and a device for processing geological information is disclosed. The method for processing the geological information includes acquiring multiple geological image graphs, determining the relation between the image coordinate and the ground coordinate of each of the multiple geological image graphs by an imaging mode of geological images, and joining the multiple geological image graphs together according to the relation between the image coordinate and the ground coordinate of each of the multiple geological image graphs. Accordingly, large-scale ground images can be acquired by processing the geological images.

The present invention provides a process for preparing ball-type desulfurizer with high sulfur capacity, comprising the following steps: placing initial balls in a rolling equipment; wetting the surface of the initial balls with an aqueous solution of an organic binder; then alternately adding non-crystalline iron oxide hydroxide and the aqueous solution of the organic binder to gradually form small balls of non-crystalline iron oxide hydroxide with high sulfur capacity and different diameters; and adjusting the shape of the small balls and then roasting or naturally drying the small balls. In the desulfurizer prepared by this method, the initial balls constitutes 0.98 wt %-9.03 wt % of the desulfurizer, the non-crystalline iron oxide hydroxide constitutes 90.29 wt %-98.62 wt % of the desulfurizer, and the organic binder constitutes 0.58 wt %-0.89 wt % of the desulfurizer. The present invention solves the problems that the desulfurizer with high sulfur capacity in the prior art has a high binder content and poor water resistance and diffusion performance, and provides a process for preparing a desulfurizer with high sulfur capacity, wherein a desulfurizer with high sulfur capacity and low binder content, good water resistance, good diffusion performance can be prepared.

An algorithm for efficiently compressing floating-point data in 3D meshes is disclosed. 3D meshes are represented by topology data, geometry data and property data. Geometry data specify vertex locations and are usually represented by floating-point coordinates. While geometry data are usually compressed by quantization, prediction and entropy coding, the present invention uses no prediction. A floating-point number consists of mantissa and exponent, and normally the exponent, sign and mantissa are compressed separately. A method for encoding floating-point formatted data comprises determining if a current floating-point value was previously stored in a memory, storing the current value in the memory if it was not previously stored in the memory, and encoding it. Otherwise, if the current floating-point value was previously stored in a memory, the storage position of the value within the memory is determined and a reference pointing to the storage position is encoded.
