Some embodiments of the invention are directed to techniques for electrochemically fabricating multi-layer three-dimensional structures where selective patterning of at least one or more layers occurs via a mask which is formed using data representing cross-sections of the three-dimensional structure which has been modified to place it in a polygonal form which defines only regions of positive area. The regions of positive area are regions where structural material is to be located or regions where structural material is not to be located depending on whether the mask will be used, for example, in selectively depositing a structural material or a sacrificial material. The modified data may take the form of adjacent or slightly overlapped relative narrow rectangular structures where the width of the structures is related to a desired formation resolution. The spacing between centers of adjacent rectangles may be uniform or may be a variable. The data modification may also include the formation of duplicate copies of an original structure, scaled copies, mirrored copies, rotated copies, complementary copies, and the like.

The invention discloses a method for forming a magnetic thin film structure having perpendicular magnietc anisotropy (PMA), a magnetic thin film having PMA and a tunneling reluctance device having PMA, wherein the magnetic thin film structure having PMA is a multilayered fabrication of materials having differing crystal symmetries that provides smooth transition by use of a seed layer that promotes symmetry matching. An interface between layers in the deposition, such as an interface between a layer of MgO and a Fe-containing ferromagnetic layer, is a source of perpendicular magnetic anisotropy which then propagates throughout the remainder of the deposition by means of the symmetry matching seed layer.

Well core data descriptions are received as input digital data for computer lithofacies modeling. Digital templates are established for carbonate and clastic core description based on reservoir rock formation analysis. Description criteria of the template for carbonate rock can include texture, mineral composition, grain size, and pore type. For clastic rock, the criteria in the template can include grain size, sedimentary structure, lithology, and visual porosity. The data and observations regarding these criteria are entered into a computer 3D geological modeling system directly. Wireline log data are integrated to calibrate with well core description to derive lithofacies. The lithofacies are exported in digital format to be entered into the 3D geological modeling system. A geologically realistic model of the reservoir can be established.

The invention discloses a dividing method based on a quaternary system unconsolidated formation sub-layer deposition combining structural model. The method comprises the steps of determining the lithology, thickness and space combined deposition structural characteristics of each stratum under the quaternary system lower-part unconsolidated formation top interface according to boring data; drawing the combined deposition space distribution graph of the quaternary system lower-part unconsolidated formation according to the deposition characteristics of the quaternary system lower-part stratum; integrating the drawn stratum with the space distribution graph according to the dividing principle of stratum lithology; performing principle dividing of stratum thickness, sequentially dividing according to the thickness of the stratum from thin to thick, obtaining each sub-layer dividing outcome under the quaternary system lower-part unconsolidated formation, and naming each sub-layer of the quaternary system lower-part unconsolidated formation; and establishing the sub-layer deposition combined structural model under the quaternary system lower-part unconsolidated formation. The dividing method based on the quaternary system unconsolidated formation sub-layer deposition combining structural model provides a reference base for coal mining and recovers a large amount of sluggish coal mine resources, thus obviously improving the social and economic benefits of mine shafts and providing guarantee for safe production of the mine shafts.

The invention discloses a flow safety early warning method for a submarine gas transmission pipeline with hydrate deposition and shedding, which belongs to the technical field of pipeline flow safety. Its early warning method includes collecting the basic information of all pipelines in the area, calculating the subcooling degree based on the type and concentration of the inhibitor, calculating the change value of the hydraulic diameter with time through the amount of hydrate formation, calculating the flow shear force of the system and communicating with the early warning system. The preset sedimentary structure stress is compared to determine whether shedding occurs; finally, the hydraulic diameter is updated, and the flow safety of the pipeline is judged according to the pressure difference between the inlet and outlet of the pipeline, and whether an early warning is required. This method realizes the dynamic identification of the thickness of the hydrate film with the size of the hydraulic diameter, reproduces the shedding phenomenon of the sedimentary structure, further improves the accuracy of pipeline prediction, and improves the safety of seabed natural gas transportation.

The invention further provides a device capable of realizing the assembly-free manufacturing method for the micro mechanical structure.

Beam-induced deposition decomposes a precursor at precise positions on a surface. The surface is processed to provide linker groups on the surface of the deposit, and the sample is processed to attach nano-objects to the linker groups. The nano-objects are used in a variety of application. When a charged particle beam is used to decompose the precursor, the charged particle beam can be used to form an image of the surface with the nano-objects attached.
