Disclosed is a cover of a combined type heat collecting tile. The cover and a grooved seat (1) are matched with each other to form the combined type heat collecting tile. The cover (2) specifically comprises an upper cover (201) and a lower cover (202); cavities are respectively arranged in the middle of the upper cover (201) and the middle of the lower cover (202), and the upper cover (201) and the lower cover (202) form a double-layer structure; and the upper cover (201) and the lower cover (202) are light-transmittance structural members specifically. The cover of the combined type heat collecting tile has the advantages that a combination form of the cover and a building roof heat collecting system is different from a combination form in the prior art, and an overlapping ratio among covers is low; high construction quality can be achieved and a good technical effect can be realized by a simple construction scheme during construction, requirements on construction personnel are obviously reduced, the labor cost is greatly reduced, and the construction efficiency is improved; and accordingly the cover has expectable huge economical value and social value.

The invention discloses a network registration method and system based on a dynamic graphic password. The method includes: a server receives a registration request sent by a client, selects a positioning factor in a positioning factor library according to the structure of a dynamic factor table of all elements, and generates a positioning factor. factor string, and send the generated positioning factor string to the client, and the client generates a full-factor dynamic factor table according to the structure of the full-factor dynamic factor table and the positioning factor string, and the user inputs two parameters through the full-factor dynamic factor table. Set a dynamic graphic password, and send the registration information including the user name and the positioning rule corresponding to the dynamic graphic password to the server; if the registration information is correct, use the positioning rule in the registration information as the user's password . In this method, the input dynamic graphic password is used as the password stored by the user, which is safer, easier to remember and difficult to crack than the traditional password composed of fixed numbers or characters.

The invention relates to laser processing and in particular relates to a prismatic irregular hole underwater laser shock peening method and a device for realizing the same. The method comprises the following steps: precisely matching a matching pin of which the surface hardness value is higher than that of a workpiece with a prismatic irregular hole, putting the workpiece in an underwater opposite hole side area and performing laser shock peening; introducing incident laser beams into the prismatic irregular hole for peening the inner wall of the prismatic irregular hole by utilizing a total reflector arranged in the prismatic irregular hole, adopting large-size square light spot laser beams in a non-prismatic area, adopting small-size square light spot laser beams in gradual transition in a prismatic area, and linearly changing the sizes of the light spots perpendicular to the edge direction in the prismatic area, wherein the sizes of the light spots are smaller at positions closer to the edge. Meanwhile, a jump mode and a thickened absorption layer are matched, the laser shock peening quality is guaranteed. According to the method, hole edge collapse and a plasma shielding effect can be effectively avoided, and the method is suitable for peening the inner wall of the prismatic irregular hole with the edge angle of less than 90 degrees and a hole edge area.

The invention provides a user verification method and a user verification system, which is applied to a network system composed of a client and a server. The user verification method comprises the steps of displaying a verification code image when the user verification is required, wherein the verification code image comprises at least one Chinese character in the horizontal direction and at least one Chinese character in the vertical direction; receiving the Chinese character in the horizontal direction from a first input field, and receiving the Chinese character in the vertical direction from a second input field; and conducting the user verification according to the received Chinese character in the horizontal direction and the received Chinese character in the vertical direction. During the user verification process, when the received Chinese character in the horizontal direction and the received Chinese character in the vertical direction are completely the same with the Chinese character of the verification code image in the horizontal direction and the Chinese character of the verification code image in the vertical direction, the user verification is approved successfully. Due to the adoption of the technical solution of the present invention, whether the verification object is a person or a computer can be judged more accurately.

The invention discloses a one-time dynamic location authentication method, system and password change method. The method includes: an authentication server receives an authentication request from a client, generates a location factor string, and includes the location factor string and all element dynamic The generation information of the factor table structure is sent to the client, and the client receives the generation information, generates a full-factor dynamic factor table, and maps the positioning factor string to the full-factor dynamic factor table, and obtains the user according to the first location. The dynamic graphic password entered by the rule, and sent to the authentication server, the authentication server receives the dynamic graphic password from the client, if the first positioning rule corresponding to the dynamic graphic password analyzed is consistent with the preset positioning rule, Then the authentication is successful. Combining the image and easy-to-remember features of graphic passwords with the variability of one-time dynamic passwords improves the overall convenience and security of the authentication system.
