The invention relates to a configuration method for area pattern in computer drawing, belonging to the technical field of computer drawing, which comprises the following steps: step one, importing the geography data into the computer and then judging the pattern type waiting for noting in the geography data; step two, deciding the noting mode type of the noting pattern according to the pattern type; step three, configuring the pattern waiting for noting according to the configuration rule of the noting mode type. The invention divides the noting configuration of the area pattern into five basic modes according to the substantive characteristics and the configuration rules of the patterns of the water system and settlement place, provides the automatic configuration arithmetic of noting of different modes according to the geometrical characteristics of the modes, and resolves the problems of collision or shelter of the different noting modes in topographic maps with full elements. The invention has the advantages of improved efficiency of automatically noting the area pattern and enhanced noting quality of the map.

The invention provides a method for manufacturing a terahertz waveguide preform of an acute angle structure by means of a 3D printing technology. The method comprises the steps that firstly, computer cartographic software is adopted for drawing a stereo structure of the terahertz waveguide preform, then, and printing is performed by means of a 3D printer piece by piece to form the terahertz waveguide preform. The method is applicable to a majority of terahertz waveguide materials including metal or polymer and composite metamaterials thereof. Terahertz waveguide (shown in the figure) of various special-shaped cross-section structures of the acute-angle structure such as a triangle and a pentagram, the structural design freedom degree is increased, embedding of high-melting metal wires is facilitated, and the longitudinal structure of the waveguide can also be changed. The method is simple, convenient to implement and low in cost, the cross-section structures of the manufactured waveguide are abundant, the performance is excellent, and the method is applicable to large-scale industrial production and laboratory investigation, exploration and application.

The present invention relates to a critical incident safety and security notification system for a building wherein upon the occurrence of a critical incident, the activation system signals a plurality of other safety and security systems to initiate, including the engagement of door barricades and informational and instructional notifications in the form of lighting, audio, text, and / or email being sent to the occupants of a building. Simultaneously, this notification system sends messages to law enforcement and first responders on a connected, web based platform and includes an integrated computer mapping system for critical incident location reporting. In one embodiment, a particular area of lighting in the building can be caused to strobe in order to disorient a shooter or other unwanted intruder, or to indicate the critical incident location.

The invention discloses a computer mapping technology and socialization method-based learning effect strengthening method, which comprises teacher side operation and student side operation, wherein the teacher side operation comprises the steps of creating a circle, releasing and dismissing activities and publishing and deleting topics; and the student side operation comprises the steps of joining the circle, participating in and exiting activities, publishing, participating in and deleting the topics, and exiting the circle. Through mapping of the circle and the topics, a group is generated, and a post is created on the basis of the circle, and is divided into two types of the topics and the activities. The learning interactivity and positivity of students are strengthened through socialization methods of the circle and the post, and the data sharing accessibility and timeliness are strengthened.

A process of UV image printing on a surface layer of a respiratory type mouth mask is provided. The process comprises following three steps: a step of computer mapping, a step of mold fixing and a step of UV printing. The UV printing process includes processing the image by using a computer mapping software, printing on the surface layer of the respiratory type mouth mask through a UV printer, and curing ink to a solid state by UV lights. During printing, the mouth mask is made of nonwoven fabric, and the position of the mouth mask is fixed through a matched mold, thus controlling the position of the image and effectively performing quantity production. Results of a color fastness test and a volatile organic compound test of the mouth mask show that the mouth mask is good in air permeability and waterproofness, harmless to health of customers, and capable of meeting economical, healthy and beautiful requirements of customers.

The invention belongs to the field of three-dimensional (3D) modeling for computer graphics, in particular relates to polynomial surface graphics, and relates to a method for non-circular curve trend extrapolation similarity intelligent extension. For connection and transition modeling with low precision requirements, non-circular curves with arbitrary shapes are frequently extended to a designated target object. According to the property that characteristic points are selected from a non-circular curve to be extended, the non-circular curve which has a shape being the most similar to the non-circular curve to be extended is selected from four typical non-circular curves to be subjected to trend extrapolation intelligent extension, high-precision extension can be carried out within a neighborhood area adjacent to an extension starting point, and the practical requirements of most graphics and modeling with low precision requirements can be satisfied. The method comprises the following steps that: points M which equals to 3m are selected from the non-circular curve to be extended and form an arithmetic progression; a similar intelligent extension model is selected; the undetermined parameters of the similar intelligent extension model are determined; a non-circular curve extension model is determined; the intersection points of the extension model and the target object are calculated; and the non-circular curve extension model is utilized to extend.

The invention provides an underground curved roadway tunneling construction method. The method comprises the steps of utilizing computer mapping software to draw a curved roadway vertical view, measuring the center chord length and the circle center angle corresponding to the center chord, mapping out the number of construction tunneling steps, calculating and obtaining the tunneling step length,the tunneling step angle and the tunneling width, and excavating and obtaining a curved roadway according to the geometric parameters of the construction tunneling steps.
